Came home today to a blazing hot house and indeed have no cool air coming from the vents. Not sure how the wife didn't notice, she's been home all day. Looking for some help to troubleshoot this.
Blower works fine, turning on/off with thermostat. Outside the house at the unit, I've tested the contactor, it clicks on and off in response to the thermostat input, and I get good continuity across the terminals when the contactor is engaged.
The condenser fan is working fine, no issues there. When the system is powered on (and thermostat set to cool) there is voltage to the compressor, but I don't get any indication that it's running-- no noise from it whatsoever. But the compressor itself is warm (almost hot) so seems to be receiving power.
I have a single capacitor on the unit, it has three terminals, yellow brown and blue wires IIRC. I'm not sure if it is a start capacitor for the compressor, condenser fan, or both. Not really sure how to test the capacitor.
Refrigerant has good pressure.
Any ideas where to go from here?
