3. Check the circuit breaker
Look at the electrical panel for a tripped HVAC or air-conditioning breaker.

+1 (855) 638-0473.When the Thermostat Isn't the Real Problem
A thermostat may appear to be malfunctioning when the underlying issue is elsewhere.For example, an AC that doesn't turn on could have a problem with the capacitor, contactor, condensate safety switch, control board, electrical supply, or air-conditioning equipment. Likewise, poor cooling can result from restricted airflow, a dirty filter, duct problems, or refrigerant-related issues.
That is why professional diagnosis is valuable. Rather than replacing a functioning thermostat unnecessarily, an HVAC technician can test the system and identify the actual failure. If your thermostat problem is accompanied by unusual noises, burning smells, water leaks, or repeated breaker trips, contact

Trying a few basic troubleshooting steps is reasonable, but certain mistakes can turn a minor problem into a costly repair.Don't keep lowering the temperature. Setting the thermostat to 60°F will not make an air conditioner cool faster if the system has a mechanical problem.
Don't repeatedly reset a tripped breaker. A recurring trip can indicate an electrical or HVAC fault.
Don't replace wiring based solely on online diagrams. Thermostat wiring varies by equipment and configuration.
Don't assume a blank screen means a dead thermostat. The HVAC system may have lost power.
