My AC condenser fan hums but will not run. I try to get it

My AC condenser fan hums but will not run. I try to get it going with a push and it makes a few turns before stopping. Changed out the capacitors and no change. Fan spins freely by hand unless power is on then difficult to turn. When removed the motor after around 30 seconds of attempted running seemed pretty warm.JA: I'll do all I can to help. How long have you been dealing with this?Customer: Stopped 2 days ago. Got capacitors today to try but no change.JA: Do you plan on doing the work yourself?Customer: Yes. I even have a spare motor.JA: Anything else we should know to help you best?Customer: I think that should cover it.

I put in a new CR24K6E-PFV775 compressor and a new suction

I put in a new CR24K6E-PFV775 compressor and a new suction accumulator in a old 38YKC024-321 heat pump condenser. It ran 3 days and stop on kicking out on the heat sensor on the compressor. I had to put on a hard start to start it up. Decided to install another compressor thinking it was a bad compressor. The other compressor ran only a day. When I got there it ran about 10-15 minutes then kick out on the heat sensor on the compressor. My sub cooling & super heat was very good. The run capacitor is new (35mf). I check the suction accumulator was install right. I wonder if it is a bunch of bad compressor such as poor design, suction accumulator oil port is stop up or they label the (IN) is label wrong. I been doing this 30 years and I haven"t never seen this before. Any Ideas?Keith

I had my Lennox A/C charged on 6/24. It needed 3+ pounds of

I had my Lennox A/C charged on 6/24. It needed 3+ pounds of the older refrigerant since it is about 16 years old. The A/C lines run from the evaporator coil which is above Lennox furnace through the attic above ceiling and out to condenser. About 3 days later, I noticed two areas in the ceiling forming water stains. A/C person said "water line" to A/C froze (this is June and I've had this A/C for 16 years. This has never happened and I live in Denver). A/C person said "they" should never have used copper line and said he would replace it with plastic line. This doesn't make any sense to me at all. He said he "braised" three area where there were leaks. Could overcharging the unit have caused this? Why would this happen after 16 years of surviving winters? Am I missing something?
