Bryant Air Handler don't start compressorA/C Compressor capacitor
Posted 05 April 2012 - 12:17 PM
My house was built in 2001.
I have Bryant Air Handler.
I can force the blower to blow, using the thermostat fan control,
But the air handler will not start the outside compressor.
I noticed this capacitor: Dietektrol VI HC91CA010D in the air handler,
could that need replacement?

Set the unit for COOL.
Remove the access panel to the condenser.
Use your volt meter to verify 220 volts at the incoming power side of the contactor.
If voltage is good there,
Use your volt meter to check the low voltage terminals on the high voltage contactor. These terminals are on the side of the contactor and probably YELLOW and BLUE in color.
If not voltage there you may be low on refrigerant and the controls are locked out on the low pressure switch.
If you do have high voltage and low voltage at the contactor,the contactor is stuck open or the terminals have ants in them.

On second thought: First it would be easier to know for sure if the outside FAN is working or not. That would rule out a lot of electrical issues. I just assumed from ur first post...

If nothing happens when you set the system to cool but the blower will run if you switch the fan switch to "on", you may have a thermostat problem. If the thermostat is digital, replace the batteries first thing. After that, pop the front off the thermostat and jump out "R" and "Y". If the outdoor unit runs then replace the thermostat.
