I have a Goodman CPKE30-1b heat pump, about 14 yrs old, dual run capacitor.
A few weeks ago when we had our first hot spell in a while, I noticed the a/c was no longer blowing cold (it had been) so I went out and checked and the compressor was not running, though the fan was. I was going out of town for a few days so shut it off. When I returned it seemed to be running fine, cooled the house down 5 degrees in about an hour.
We then had a cool spell where the a/c did not run for a week or so. On the first hot day I turned the a/c back on, at first it was blowing cold air but a half hour or so later I noticed it was not. I checked outside and this time the compressor was running but not the fan. Turned the thermostat off for a few minutes, then back on - this time the compressor and fan both ran for a couple minutes, then the fan speed dropped for a couple more minutes, then stopped with the compressor still running.
There are some spider webs in the control unit that I am about to clean, but I don't see how they would cause problems like that. I am also about to perform some voltage checks on the cap and contactor, which results I will report back, but I thought I would post this now in case there is a common problem that could cause this type of erratic behavior.
