condensor runs or doesn't turn off with air handler - thermostat?
This started last week where my air handler would run and run but the a/c condensor wouldn't come on. I shut off the breaker and turned it back on and then it's been okay for a while until this morning. I noticed the condensor running outside even though the air handler was off inside. Flipping the thermostat doesn't seem to do anything but turn the air handler on/off. The only way to turn off the condenser was flip the breaker.
What could this be? Wiring at the condensor? New thermostat? I can install a thermostat myself, but wiring out at the unit I'll have to call someone.
