My heater won’t turn on!

If your heater is on the fritz, you can’t wear wool socks and sit around the fireplace and hope it comes back on. It’s time to get to the bottom of the problem, and we’re here to help.

Continue reading this article to learn the top reasons your heater won’t turn on and what you can do about it.

1. Clogged Filters

Something as simple as a clogged filter can cause major problems for your heating. Check your filters and see if they need to be replaced.

Keeping a check on your filters on a regular basis is a good practice, but even if you check often, it’s still possible that your filters can become clogged.

2. Improper Thermostat Settings

If your heater won’t turn on, make sure it’s not a problem with the settings on your thermostat. If your heater isn’t set to above room temperature, it’s not going to come on.

You may also find that the thermostat isn’t on the proper setting. If the heater setting isn’t set properly, it could continue to blow air, but not blow heat.

3. Power to the Furnace Is Off

Even if your furnace is gas, it still uses electricity. Look at the fuse and circuit breaker at the electrical panel to make sure there isn’t a problem with a tripped breaker.

Look at the furnace breaker and see if it says, “On.” If it does, then move on to the next possible problem. If It’s set to “Off,” then turn it on and try the heat again.

4. Dead Blower Capacitor

The capacitor starts your furnace when it’s time to run. You should keep a close eye on them because they fail often. When your heating professional does your regular maintenance, make sure to ask them if your capacitor is on its last legs.

If your capacitor won’t start the blower, it could cause the blower to malfunction, which will be a much more costly problem than replacing the capacitor.
