Question about Heating & Cooling
I just bought a new house, and I cannot set my honeywell thermostat. If I try to make the house cooler and press the down temp arrow, it will display that the "set" temp is changing, but the unit doesn't turn on, and the current room temp doesn't change. We have the thermostat set to cool and the fan is on. Any suggestions?
Okay. Here's what I suspect in order of probability:
- low refrigerant charge
- contactor not getting 24 volts from controller (controller problem)
- bad contactor
- bad capcitor
I'd start with the charge, as suggested by mastatech. But if it is low, you'll need a service call, anyway, so pressing the needle valve may not be necessary.
I'm assuming you're not going to be taking the unit apart and testing stuff, so you'd need a service call for that as well.
I guess bottom line is, call for service. At least, I think we've ruled out simple stuff which will avoid paying for a service tech to come out and flip a switch.
Maybe mastatech has some other recommendations.

Check the outdoor unit it could just be turned off at the circuit breaker if it is runninng outside and the air out of the top is cool. Either the compressor is not running or there is no charged. just press in the needle valve to see if it has a charge.
