What Do You Do When Your Furnace Wont Stay On?
When your furnace won’t stay on, first check the thermostat to make sure it’s set to the correct temperature and the fan is on “auto.” Next, check the air filter to see if it needs to be replaced or cleaned. If the furnace still won’t stay on, check the circuit breaker to make sure it hasn’t tripped. If none of these steps solves the problem, it’s best to call a professional HVAC technician to diagnose and repair the issue.
