Troubleshooting Tips for When Your Heater Won’t Turn On
Check Your Furnace Power Switch and Circuit Breaker
One of the first things to check when your heater fails is the furnace power switch. It can sometimes be accidentally turned off. Resembling a light switch, it is typically located near the furnace.
Also, check your home’s circuit breaker. A tripped circuit breaker is a common culprit and can be easily overlooked. Resetting the breaker may solve the problem if it has flipped to the “off” position.
Inspect the Furnace Filter and Air Ducts
A dirty furnace filter can restrict airflow and cause your heating system to shut down due to overheating. It’s a good idea to check and replace air filters regularly to maintain optimal airflow and prevent potential heating issues.
Additionally, blocked or leaky air ducts can compromise your heating system’s efficiency by restricting airflow and dispersing heat unevenly throughout your home.
Examine the Gas Line and Gas Valve
For homes with a gas furnace, ensuring that the gas line is open and the gas valve is functioning correctly is crucial. If you suspect a gas leak due to the smell of gas near your furnace or other gas appliances, it’s important to act immediately. Shut off the main gas supply, evacuate the area, and contact professionals to address the issue safely.
Pilot Light and Ignition System Issues
Older furnace models with a pilot light may fail to ignite if the pilot light has gone out. Relighting the pilot light according to the manufacturer’s instructions can often resolve this issue. For newer models with electronic ignitions, the ignition sensor could be dirty or faulty. A malfunctioning ignition can prevent the furnace from firing up and may require professional servicing.
Problems with the Blower Motor or Furnace Flame Sensor
The blower motor circulates air throughout your home’s HVAC system. If it malfunctions, it can prevent your furnace from turning on. Similarly, a faulty furnace flame sensor, which ensures that the gas burns safely, can cause the system to shut down as a safety precaution. These components may require inspections and repairs from a qualified HVAC technician to ensure they function correctly.
When to Call a Professional HVAC Technician
While some troubleshooting steps can be performed without expert help, certain furnace problems should be addressed by a licensed HVAC technician. This is especially true for issues involving gas furnaces and complex system components like the heat exchanger, furnace blower motor, and furnace door switch. Regular professional maintenance can help prevent unexpected breakdowns and extend the life of your heating system.
