Ways To Fix A Furnace That Is Not Heating

  • Tripped Breaker Of The System: Check to see if the circuit breaker has tripped or if the furnace still does not operate even after turning the switch on. If this is not the case, check for a tripped circuit breaker and, if possible, attempt to reset it.

    A blown fuse or tripped circuit breaker may indicate a more serious problem with your home’s electrical system that requires the assistance of a professional. The best course of action is to be extra cautious and have a licensed electrician or HVAC specialist evaluate it.

  • Issues With The Thermostat: Furnace problems are typically caused by the thermostat, which serves as your heating system’s command and control hub. Change the thermostat’s setting from cooling to heating, raise the temperature by five degrees, and then check to see if the heating system comes on to diagnose the problem.

    If it is malfunctioning, the problem may be as simple as a lack of batteries in the thermostat. When the thermostat’s batteries run out, the display will become unusable, and it will no longer be able to manage the home’s heating and cooling system. A simple yet effective solution to this problem is to replace the batteries once a year.

  • Ensure That The Filters In Your Heating System Are Clean: The home’s furnace needs a constant flow of fresh air to keep the residence warm. If your forced air system’s air filter is clogged, it will not be able to supply your heat pump with the air it needs to maintain a suitable temperature in your house.

    In turn, this will prevent your HVAC system from activating. Your system depends on regular airflow, and your heating system may only activate if it receives enough fresh air. Your system requires constant airflow.

  • Ensure That The Pilot Light Is Lit: A faulty or dirty ignitor or sensor is at blame if your furnace turns on and goes through the motions of starting but does not ignite. This is one of the most frequent problems with furnaces.

    When everything is functioning normally, the thermostat instructs the furnace to switch on; the ignitor reaches a temperature where it lights red. The furnace begins lighting the gas and blowing warm air into the room.
