Question about Frigidaire FAS155K1 Air Conditioner
I have a 1997 Bryant 561c A/C outdoor condenser unit which had the dual capacitor (40/5 370) replaced a few years ago and was running fine. A week ago the condenser fan stopped again so I replaced the cap with the proper replacement but this time without success. The unit is currently turned off at the outside disconnect.
1) When powered up and thermostat at cool, the fan runs at 1/2 speed (~500-600 rpm) but I was getting cool air inside. After 5 mins or so it over heats and shuts down.
2) When the thermostat is off, the fan hums like it is getting some power but does not turn. I need to pull the disconnect to stop it.
3) When I turn the thermostat to "heat", the fan actually turns very slowly in the opposite direction.
I noticed a small spot almost like a gray colored burn on the top of the cap after rechecking the system so I think the new one fried.
It looks like the contactor is operating correctly but I do see some black on the contacts. I tried manually pushing the contacts closed (with an insulated screw driver) and there was no difference.
Any ideas what I should target?

SOURCE: CONTACTOR IS NOT MAKING CONTACT
Hello. Make sure you are getting 24 volts to the contactor coil, you can check by using a multimeter and put the probes of the multimeter to each side of the coil ( not the contacts) if you are not getting 24 volts than u must check the low voltage wiring to make sure there is no loose connection. also check the thermostat to make sure it is wired properly.
