HVAC Refrigerator coil cleaning.

[anothercoronaplease]

You didn't show have to actually clean the coils which are the most difficult to get to.



[jm79design]

Thank you for sharing this valuable info. I just had to thaw out the coils inside the fridge because it wasn't cooling and they were frozen over and this will be my next step.

[DrZarkloff]

@jm79design Thanks for watching.

I have a question, I have a fridge from 2003-2005 and it has cutom temp controls with a little 2d display , it has been in storage for 1 or 2 years and when i want to set the temp, the display will change from 0 degrees for freezer to a 38 degrees, and fresh food area will go from 37 degrees to 57 degrees and when ever i change the temp back to the correct temps that i want the display will change the temp again, could this be a problem or can it just be saying the temp will gradually go to good

[DrZarkloff]

@callofdutyguy9 I don't know why the setpoint is changing on its own. It could be that your temp control is going bad.

[callofdutyguy9]

@DrZarkloff problem is slved, set it to trubo cool and truned it off when the temps reached the set points, they bounce around a bit, but the fridge is still doing its job

thanks!

I wish the coils on my Fridge were that easy to get to. The coils are actually behind the compressor. Have never had any problems with temp in fridge getting warmer but decided to do this anyway. Helps efficiency. By the way: someone left a comment saying that their fridge had R12? I didn't know fridges ever had that type of refrigerant. My fridge has R134a.

[DrZarkloff]

@HCVguy93 R12 used to be the refrigerant of choice on nearly all refrigerators before 1995.

[HCVguy93]

@DrZarkloff Yeah I was thinking about that because it was the same way with automotive A/C's. Today's cars use R134a also.

[crawhip2]

@DrZarkloff

Was the ozone problem the reason why they shifted over to R-134?

[DrZarkloff]

@crawhip2 Yes. R134a is a HFC refrigerant. R12 was a CFC. All of the CFC refrigerants are no longer made or sold. Currently, HCFC refrigerants like R22 are being phased out. By 2020, you won't be able to buy HCFC refrigerants.

[JISINSANE3]

@DrZarkloff What the government fails to tell everyone is that r134a and r410a causes global warming big time. They need to go back to amonia, Propane, and sulfur dixoide which are way more efficient anyway, Even know dangerous, Sulfur is the best and most safest and should be used again.

I haven't had a honey-do day once, since she moved out, and I'm happy! Good video by the way.

[whatsdat]

LOL, Forgot to tell everybody to Unplug before they Start. Electric shock, ouch.

[bpereztab]

Thanks!

[bpereztab]

My fridge (GE) was warmer than usual - cleaned out the coils underneath the unit - took a temperature reading and it's at 35 degrees (F). The unit is at least 12 years old. At what point would we have to recharge the refridgerant (R12)?

[DrZarkloff]

@bpereztab The freezer part of the fridge should be zero degrees F. The cooler part of the fridge should be between 35 and 40 degrees F. You should never have to recharge the system unless it develops a leak.

[koreadude]

the refrigerator has been a bit warmer lately so im goanna try this out and see if it works lol

[DrZarkloff]

Thanks for watching.

[Piercetp]

That was a lifesaver. Thanks.

[DrZarkloff]

Thanks for watching.

[caddykidd]

well i called my brother and he came over and helped me drink all the beer in it, because it was to heavy to "pull out from the wall" then we realized when we "pulled it out from the wall" that it had fallen over, so we grabbed the air hose (open the garage door first) and cleaned the coils on my domestic....and cleaned the garage floor. our day turned out to be 100% efficient, I think, we cant really remember.....  thanks for the idea.

[DrZarkloff]

LOL! It sounds like a good time was had by all.

[irish77777]

HELLO MY VIEWERS ....Love it

[Emisanboo]

I've had my fridge for about fifteen years and it never occurred to me to clean the coils. Of course it makes complete sense to do so. Your video was very helpful. I'll add "clean fridge coils" to this week's list of chores!

[HDXFH]

that looks like a matsushita compressor

[thecarexpert18]

when u pluged in the refrigerator is it normal to see that little blue spark?!

[DrZarkloff]

It is if your refrigerator compressor comes on right away.

[itscool1968]

one trick we use is compressed air and a small dryer duct brush works good for the coils:)

[DrZarkloff]

I usually use nitrogen to blow the dust from out of the coils when there's no food on the counters.

[risc19]

My mother say thanks Jim as i just cleaned our refrigerator coil.

[DrZarkloff]

Please tell her that she's welcome.

[OcRefrigeration]

Did you say to Unplug the Refrigerator first at all? i did'nt see that in the video.

Safety First ...

Cool video. DR. z.

[DrZarkloff]

Thanks.

[DrZarkloff]

a few times per year.

[ginzalzman]

I like to ask you how much would I have to spend on a new HVAC system? I have 4bedroom, 3bath, 3000sqft home.

[DrZarkloff]

You really need to call an a/c company to give you a quote. There are way too many variables to consider. The sales person will need to figure out how large of a system you need, check your existing duct and find out from you how energy efficient of a system you're willing to buy. Thanks for asking, though.

[southsidebmoremd]

i hope im as good as you when i finish hvacr school. your videos are very helpful. keep up the good work.

[DrZarkloff]

Thank you very much for the great compliment.

[itscool1968]

what make is youre vac it looks like a knock off of the old classic compact vac.

[DrZarkloff]

It's a TriStar. The nickname for it was the pig with the golden tail. My wife and I bought it eighteen years ago and it's still going as strong as ever. I'll never regret the $1700 we spent.

[itscool1968]

ok can we do a demo video of it?P

[itscool1968]

good video dr z but some of the ge line has the coil behind a panel that has a millon bolts you have to remove to get to it.

you might want to see if yo can do a video of one of those.

and rember the older ones have that nice low speed fan that likes to nip if you get to close:)

[DrZarkloff]

OMG! Must I? Well, okay I'll see if I can find one.

[itscool1968]

no you musent but would cover the newer type fridges.

youres is the older type that was when they was built to be service friendly:)

[mechanicwarrior20]

After you cleaned the condenser coil did you run off and let your wife clean up the dust bunnies lol

[DrZarkloff]

She wouldn't let me run off until I cleaned up after myself. She helped, though.

[Priorityheat]

You would think a HVAC mechanic would know better. I cannot remember the last time I cleaned my refrigerator condenser. Thanks for the reminder and I will save electricity!

[DrZarkloff]

I'm just glad to be a service. Thanks.
