Does the thermostat control the compressor?
Once a user sets the desired temperature, the thermostat maintains that temperature by controlling the flow of electricity to the compressor. If the thermostat is the brain, the compressor is the heart of the operation, responsible for pumping the refrigerant through the coils.
Why can’t I change the temperature on my thermostat?
Check the settings: Changes in settings could be caused by weak batteries or thermostat malfunction. Make sure that the thermostat is set to provide either heating or cooling, as needed, and that programmed set-points are correct. Make sure the thermostat is mounted in a position where it isn’t too hot or too cold.
Can a thermostat stop the AC from working?
Under most circumstances, a bad thermostat will not have any effect whatsoever on the air conditioning system. The AC system is a completely separate entity; the only connection it has to the engine is at the compressor pulley, which derives its power from the crankshaft.
Can you bypass a thermistor?
No, if the thermistor is broken, you can’t bypass it. It needs to be replaced.
How do you remove an old thermostat from the wall?

What should I do if my thermostat is not working?
Check to make sure your replacement thermostat is working. Set the thermostat so the furnace and the air conditioner will come on at different times. Give your furnace and air conditioner at least 5 minutes each time to activate. If the thermostat does not work properly, retrace your steps to see where you made a mistake.
When does a heat pump control the thermostat?
When controlling a heat pump, heat comes on during cooling cycle. When calling for cooling, both heating and cooling are energized. The thermostat is configured for a heat pump. Configure the thermostat for non-heat pump operation
What to do if your refrigerator bypasses the thermostat?
If the refrigerator begins cooling after running the bypass, you’ll know the built-in thermostat is defective. Open the refrigerator door to dial the built-in thermostat control to the coldest setting. Unplug the refrigerator power cord from the wall outlet and plug in the cord to the socket on the back of the external thermostat.
