very good video alot of info.would like to see videos on how to find the problem. thank you
-
@niper99 i think so

lol @ ratcheting wrenches

the videos are great!!!
l have a question, l have a older keeprite ac unit about 15 years old, it recently started blowing fuses in the panel, not all the time but every 2 or three days of runnig it will pop one, it has a small start capacitor sigle pole and daul pole bigger one, l havent tested them yet:), l was wondering if u have a weak capacitor will it cause the compressor to draw more amps on start up and cause a blowin fuse?,

Dr. Z on my hvac schematic the dual cap shows current flow from C to HERM and from C to FAN. The start cap w/resistor shows current flow in one direction but the physical start cap does not. Does it matter which wire goes where? Also how do you test a start cap w/resistor? Thanks.

@1original11 It doesn't matter which wire connects to herm and which connects to C.

I think the stuff thats leaked out the old potential relay is in fact sealing glue thats put on in the factory, like some have the screw that holds the two parts of the relay together sealed over with silicon style stuff, but i'm only looking at a vid and not the actual relay. Great vid as usual :-)

Dr. Z I have a question about the Run and Start capacitors. As a student in the HVACR Industry at a local Tech School, I'm being told to use a 1M Ohm resistor to bleed out the voltage instead of a screwdriver becuase of the internal protection on newer caps. What is your opinion and secondly, could you show a video of correctly bleeding them out to where we can service them?
Thanks Dr. Z, I love the videos, keep them coming.

Thanks for the comment. Using bleed resisters is a great way to discharge the capacitors.
