Can You Hear Your Furnace Click On, But It Does Not Fire Up?
There are numerous reasons your furnace won’t heat your home when you turn it on. Sometimes the issue can be simple and easily fixed, while others can be more serious and need a professional. Either way, it’s important to diagnose the problem as soon as possible to get your furnace up and running again. Call our experts at Equi-Tech Mechanical when you need furnace repairs in Apache Junction, AZ, and the surrounding areas.
Your furnace may not start because:
- The circuit breaker: Your furnace could be clicking but not firing up because the circuit breaker is overloaded or has blown. The breaker can overload because of a problem with the electricity supply to the furnace. This may cause the motherboard to fail and for the burners not to fire.
- Dirty air filters: Something so small can have a big impact. When you have a dirty filter, it restricts the airflow to your furnace. This makes your furnace work harder, which can cause it to overheat and shut off. We recommend that you clean or replace your air filter regularly.
- The furnace switch is turned off: This one seems pretty obvious, but sometimes in the hustle and bustle of everyday life, we forget to turn the switch on to our furnace. Make sure that the switch is turned on, and if it is, check to see if there is power going to the furnace by checking the circuit breakers.
- A gas line issue: Another reason for it not working is that the gas line simply isn’t turned on. Check to see if the gas is on. If it is, and your furnace still doesn’t turn on, you may have a leak in your gas line. If you smell gas, leave the area immediately because it’s incredibly dangerous.

- The pilot light could be faulty: This is actually the most common reason your furnace won’t start. The burners won’t come on if the pilot light is out. A compromised thermocouple is usually the culprit for the light going out. The thermocouple can be affected by dirt and damage.
- A bad igniter: If your furnace uses an electronic igniter to create a spark and light the gas, it may need to be replaced if it’s not working properly. A telltale sign of a lousy igniter is a clicking sound when you turn on the furnace, but the burners don’t ignite.
- A blown fuse: A blown fuse will cause your entire furnace to stop working. It would stop working if the furnace is getting too much power and blows a fuse to prevent any damage. Another reason why the fuse will blow is loose wiring.
These are only some of the main reasons your furnace might not work when you turn it on. If you have tried these tips and your furnace isn’t working, call one of our professionals to look at it.
