Why Won’t My Heater Turn On?

Cooler weather has finally come to Brea, CA, and chances are you’re going to be running your heating system more and more often as fall turns to winter. It can be quite a shock to turn your heating system on, only to have nothing happen. It’s usually a sign of a serious problem for obvious reasons. You should never try to diagnose or repair a heater that won’t turn on yourself, though you can perform some basic troubleshooting. The more you understand about why a furnace shuts down, the better you’ll be able to react when trouble arises.

Basic Checking

Before summoning the cavalry, you should perform some basic troubleshooting steps to ensure the problem isn’t’ easily correctable. Check the breaker box to make sure the switch powering your heater hasn’t been triggered, and reset it if it has. Then run the heater and see if the problem returns. If it doesn’t, you should be good to go. You should also check the thermostat to see if the settings are correct, or if they may have been adjusted by another family member without telling you. Only when these steps have been taken should you turn the system off and call for repairs.

Possible Causes

With modern heaters, the system has safeguards that will automatically shut it off in the event of danger. This can be something severe, like a gas leak, or something minor, liked trapped hot air that will further damage other components. Either way, it’s shot off to keep your family and the system itself safe.

Another possibility is a problem with the fan motor or a similar component, which may be suffering from a faulty electrical connection or similar issue. That means the fan won’t run and there will be no noise, even though the system is technically “on.”
