    Your question got me curious since I had never tried saving other people's pictures viewed in Tap-a-Talk, so I gave it a try. If you tap on any particular picture to view it full screen you should...

    I have installed many of these with great success when the flat part has rusted off the compressor terminals. It's called Term-Lok. Takes some time and patients to do properly, especially if you...

    Don't want to get too technical in an open forum. Suggestion, study your wiring diagram to get a good mental picture of the circuit then start testing at the beginning. If that gives a good voltage...

    Good example of how vacuum alone is not a definitive leak eliminator. I like the idea of blocking off that part of the circuit if it is for sure only 10%, which will most likely not cause freezing.

    It'll cause slightly elevated humidity and grow all kinds of weird bacteria if it doesn't drain properly.

    My personal unit, mid 90's Trane packaged heat pump, had been slowly sinking on the...

    That's pretty close to what I did. All joints were glued and the threads so rusted around the fitting that it wouldn't budge without most likely breaking the threaded part off so I cut it about 3/4"...

    That's what I get for using a cheap meter to test caps. :D

    That's a good point, Solstice, a good start capacitor can get a compressor going even when the run capacitor has severely weakened or gone bad, so that is a good reason to check those run caps while...
