Hey man, enjoy your videos... Got a question.. What advice can you give me on a split system 3 ton heat pump unit that runs continually?? Any troubleshooting advice?? Appricate if you can help out
Why didn't you have your high side hooked up? How do you determine that it's running propery just from suction pressure and not superheat or subcooling? Thanks!
@ljmike1204 More than likely, if another lizard gets under the board again, the acid from the corpse will eat away too much of the insulation under the board and cause it to short.
One of my 49 year old units wouldn't start at the beginning of the cooling season two years ago. Opened the case and there was a mummified mouse stuck in the contactor. I had left the crankcase heater energized and the warmth must have attracted him.
@wholeNwon WOW! 49 year old unit? That beats the oldest POS that I've ever worked on. The oldest unit that I have to keep running is only 45 years old. Here in North Central Florida we get a lot of squirrels getting into the control box. The wiring seems to get in their way so they chew it the wires. I can't figure out how they can chew into a line voltage wire and not even get a weird looking smile out of it.
Thanks for the note.They were 2.5 ton Carrier R-12 systems and I did most of the maintenance on them myself. Very little was ever necessary, but parts could be difficult to source. They were very well constructed and solidly built. Both had TXVs, sight glasses, real service valves, accumulators, crankcase heaters, delay timers, etc. I could have kept them going but a good local company gave me such a great price on a quality installation that I couldn't say no.
@Simeonx1 Hey, them old Trane units don't owe anything to anyone. Micro leaks can be remedied with a stop leak additive. As long as you have a dry system the additive shouldn't hurt the system.
@DrZarkloff Locomotive diesel trains . Yeah theres green die in most of them , Do you need a uv light. i can pick up most of the leaks with my eye,. How can you read the site glass after its added?
@Simeonx1 Why would we discuss Locomotive trains w/ this video? How do Micro leaks have to do with a Lizard gettin fried? LOLYour post back to DrZarkloff was not displayed when I commented back either. Seriously, and watch the language.
People please be careful trying to work on this type of equipment without training. At the very least don't forget to shut off the power first. Quality repairs aren't as expensive as you might think.
Just noticed you are a bit free and easy with your fingers into the wires with 250v around.I know the board may have been off at the time but a mention for electrical safety would be in order.
@Aussieuke You're right about the safety thing. I had pulled the disconnect to the condensing unit before I worked on it. The coil voltage that you can hear is coming from the control transformer in the air handler.
@smc3284041 I could be that the system has a refrigerant leak or that the system has a variable speed condensing fan motor for running in cool mode during cool outside temps. Just a guess.
were u able to revive the lizard? ?? now that wouldve been impressive
So what would you charge the normal customer for that service call i understand it was ur neighbor and probably gave a break but i often find similar quick fixes and i feel i undercharge for it
This is the kind of video I have been looking for. Service calls in the real world! I would really like to see more of these. I enjoy taking my limited knowledge and troubleshooting along then reaching past what I could do. I'ts a fun way to learn and you make it interesting. Thanks
Wow, your not going to believe this Dr. Z but .....sometimes I watch your videos before I go to work to PUMP ME UP!!! well after watching this video the exact same lizard scenario occurred on my call!! There is just enough ventilation space for the defrost circuit boards that reptiles are attracted to the heat source.You can see the burn markings on the back of the board where the short happened!
@yesak789 Thanks for watching. Believe it or not, I've already pulled two lizards on separate occasions out from under the defrost board on this air conditioner.
but but before the signal gets to the contactor it has to make it through two series sensors. A High pressure cutout and a low pressure cutout. The high side sensor is normally Closed, the low side is open and thus the contactor will not turn on. I cannot diconnect that sensor. It does not screw on. It appears that i I remove it I will start loosing gas so I am having someone come out to replace it for me and check the gas level. But your videos allowed to find the problem. Thanks again.
Yes I am sure I am looking at the secondary. once I figured out how these AC units work using control lines to trigger a relay it became easy. my transformer has 5 terminals on the secondary as I can measture the output. two of them are 24 volts. one set is going to the fan and one set is going to the AC outside unit. When the thermostat is acitve I do indeed have 24 volts out to the outside unit
Hi Dr. Z. Thanks for replying back so fast! The roof top units we have are made by Engineered Air and there are a few different ones as well. I will work on a video to show you what we have and to zero in on the specific problem. And just a note to say, that thanks to you, I am now the proud owner of a brand new H636. I called the guys at Fieldpiece. I mentioned your name and they said your a great guy! They set me up with a distributor in Calgary. Thanks and talk to you soon!
your Video is helping me trouble shoot my problem. your videos helped me understand where these parts are and how they work. one thing I am confused about however is my transformer secondary has 5 outputs. the thermostat is connected to three of them (Rc, Y, G). any idea what that is about? Thanks
@abedj1220 Are you sure that you're not mistaking the five wires for the primary inlet wires? One of them will be the common wire, one will be for 120 volts, one will be for 208 volts, one will be for 240 volts and the other will be for 480 volts.
Dr. Z, All you videos are great! I've been working as a Building Operator for 3 years up here in Alberta, Canada. My Boss Is thinking of retiring in the very near future and I may have to take over. I find myself trouble shooting on 18 roof top units alot of the time. Could you do a few videos on the big commercial units. Thanks so much for all you do for us out here EH!
DrZ, what state do you live/work in? And how would you suggest someone get into hvac if they want to focus primarily on home service calls? And where is the "big money" in hvac?
Talk about a good ole fashion school lesson in HVAC. I love this guy's videos. I enjoy learning from the guys that have years of experience and that have patience to teach. Perfect combination. Nice videos Dr. Zarkloff.
it was a sevice call demanding for cool or heat? and if ti was for cooling why did u check the reversing valve? instead of checking the contactor's coil
@DrZarkloff aahh... it just looked like you put them on after you swapped out the circuit board.. just thought it was strange youd want to enter the system if it was running fine after the board was reinstalled...
This video was great it allow me to see the actual troubleshooting work. As a student who is taking Hvac class now your videos help alot thanks and keep up the good work, and the camera person too.
let me ask you a question about this video....if you pressed the contactor with a screwdriver alllowing the voltage to go to the compressor and fan will that start the unit?....I seen that u did not get your 24 volts to the conctactor coil but if you pressed down the contactor buttom (swithc-uknow what I'm talking about) it will get the voltage to start
Dr.z be carefull with the snake coiled around the compressor, lol, that's what I like about this trade. You never know what you will find on your next call!
dr. z during the winter do you post any videos on oil furnaces or gas furnaces. i am currently attending college for this trade and our instructor doesnt touch too much on furnaces as far as hands on are concerned, plenty of book work but not too much work in the shop
Thanks Dr Z for your teaching us new HVAC/R tecks how to trobuleshoot and find problems with units out in the field. im in one of the best schools in Chicago, and am learning alot from your videos along with my hands on experance in class. on the other hand, what should be the first thing a field service teck should look for when troubleshooting Heating and air condicting units?
@darkenshrine i am glad you don't work on my ac have you ever heard of superheat and subcooling. not very professional i wouldnt want you to lick your finger stick it in your ass point to the sky and charge my ac
@atifirepro7 Well I have had enough of you incompetence. Don't worry though every time I see a bad install, poor service techniques or take a shit I will be thinking of you and how fortunate I am that I don't have to run your callbacks.
@topdoozie1 Ok, make some more videos fu*k boy. Teach wiring through colors rather than circuits and dismiss carrier's own claims that those pleated filters reduce air flow by 40% (while drawing proper amperage you dumbass). I will shut you down all day long because your a punk kid that thinks he knows everything because you went to some bullshit vocational school. Shut your mouth and quit being a douchbag, go get some pussy you ugly bastard.
Great video! I'm in school now, in Wilmington, North Carolina, for HVAC. I heard of your videos from a fellow student. I'll definately be checking out all of the videos you posted. Thankyou for posting them!
P.S. I've got a pet bearded dragon lizard at home, I will definately keep him far away from my condeser unit when I take him outside! lol
I was right there with ya, when you took a drink of water, blurred vison, sticky hot, humid, up here in SC. Hot! Stay Liquidfied, Gatorade puts the salt back in ya. Stay cool Doc!
Florida... Gotta love the bugs and creatures. This is something I have to tell my instructor. I am currently going to an HVAC/R school in ohio. Thats funny it was shorting out the defrost board. Could you do a video on ladder diagrams? Thanks for the great video's. I've told fellow students about your skills in teaching. It seems if you enjoy it a person does better than if it is their job. In my case at our school.
huh, i woulda put a new crimp connection on that loose wire... a gecko(well, you called it a lizard) but, dang? yeah, thats twice now that i scene it pays too look at the back of the control boards. nice vid.
@DrZarkloff I grew up on Homestead Air Force Base. I know all about the critters. Scorpions, Lizards, Bannanna Spiders, Giant catapillars, Frogs, Crabs, alligators, Praying mantis, Roaches, toads, all kinds. Great vid Dr. More service call vids if possible. Thanks
Great video........Are you able to do a video on how to read the chart to add refrigerant to a condenser. And how to work the gauges! I think a lot of people could use this information.
i had a bat stuck to mine question wasnt the hi side pressure a bit low at 200 or was it just that it needed to run a while, i still have problms figuring proper charge i know how to do it but not sure how long unit needs to run to level out
@waters65 We have plenty of bats where I live. It's strange to think that they could get into the control panel. An air conditioning system takes about 15 minutes to level out.
Dr.Z the fan started then stopped. I would of looked at the contactor first. Did this cross your mind? We know that the problem was the lizard behind the board but what was it causing? Why did the A/C turn off after several seconds? Was the lizard pressing the reversing valve? But if it did wouldn't the customer get heat inside? Thanks Doc.
@gordy19741974 Actually, the lizard was keeping the reversing valve from energising so it was going into heat. I looked at the contactor first to see if anything looked out of place. I suspected the board especially after noticing the reversing valve coil was energising and de-energising as I pulled on the wire.
@DrZarkloff i should of guess'd that in the video, soon as you wiggled the wire, and recalled exactly how hot it was in the house. didn't click though lol, in my mind... not the reversing valve.
Lol i had a similar call were there was a beatle caught between inside the contactors contacts...he wasnt so conductive, i just replaced it with a covered contactor like the 1 in this GREAT VID :)
Hey Doc Z WE MUST BE ON THE SAME FREON WAVE. I DID MY NEIGHBORS TODAY. 4.5 LBS R22 CHARGED AN THE OTHER ONE 12OZ CHARGE. HOW SWEET IT IS. NICE DIAG CLIP

Florida... Gotta love the bugs and creatures. This is something I have to tell my instructor. I am currently going to an HVAC/R school in ohio. Thats funny it was shorting out the defrost board. Could you do a video on ladder diagrams? Thanks for the great video's. I've told fellow students about your skills in teaching. It seems if you enjoy it a person does better than if it is their job. In my case at our school.

Great video........Are you able to do a video on how to read the chart to add refrigerant to a condenser. And how to work the gauges! I think a lot of people could use this information.

i had a bat stuck to mine question wasnt the hi side pressure a bit low at 200 or was it just that it needed to run a while, i still have problms figuring proper charge i know how to do it but not sure how long unit needs to run to level out
waters65 1 year ago
@waters65 We have plenty of bats where I live. It's strange to think that they could get into the control panel. An air conditioning system takes about 15 minutes to level out.

How about sealing the perimeter behind the board with silicon sealant. Leave tiny gap at bottom for drain/vent.

@birdwing98 That would probably work. I might just do that if another lizard gets in.

Dr.Z the fan started then stopped. I would of looked at the contactor first. Did this cross your mind? We know that the problem was the lizard behind the board but what was it causing? Why did the A/C turn off after several seconds? Was the lizard pressing the reversing valve? But if it did wouldn't the customer get heat inside? Thanks Doc.
gordy19741974 1 year ago
@gordy19741974 Actually, the lizard was keeping the reversing valve from energising so it was going into heat. I looked at the contactor first to see if anything looked out of place. I suspected the board especially after noticing the reversing valve coil was energising and de-energising as I pulled on the wire.
DrZarkloff 1 year ago
@DrZarkloff i should of guess'd that in the video, soon as you wiggled the wire, and recalled exactly how hot it was in the house. didn't click though lol, in my mind... not the reversing valve.
