What’s Really Going on When Your Furnace Won’t Start, or Stop

furnace-wont-start-stop-There are few appliance issues that are more disconcerting than a furnace that won’t work right in the middle of winter. Granted, Los Angeles doesn’t get nearly as cold as cities in the Midwest or the East Coast, but that doesn’t mean we don’t appreciate a fully functioning furnace when it does get cold!

Two of the most common service calls we receive in regards to furnaces are about systems that won’t start, and also about furnaces that won’t stop running, conversely. Keep reading to learn more about what’s going on when your furnace malfunctions in this way, and give us a call for quality Los Angeles, CA furnace services to resolve the issue.

Why Isn’t Your Furnace Turning On?

There’s a few potential causes for this type of furnace failure, some more serious than others. One possible scenario is that it isn’t the furnace that’s failing at all, but rather there’s an issue with the thermostat.

Check your thermostat first to ensure that it’s actually in heating mode, and then also check to ensure there’s not a problem with the wires connecting the furnace to the system (be sure to turn the circuit breaker to the system off first when you do this, for your safety).

A lack of power could also, of course, prevent your furnace from turning on. You might have a tripped circuit breaker, or perhaps there is a power outage in your neighborhood. It could also be an issue of no pilot light—did you check to ensure yours was lit?

In the absence of the above mentioned issues, you might have a more serious problem on your hands. Hopefully, you had furnace maintenance done before the heating season began—which will eliminate the risk of most major furnace failures. If not though, it’s time to call in a professional!

But What If It Won’t Turn Off?

A furnace that won’t turn off may again be a thermostat issues. If your thermostat is malfunctioning, it might not be able to accurately signal to the furnace that your desired temperature has been met and it is time to shut off.

Another issue could be that you have the temperature set too high, or your furnace’s filter is too dirty. Either of these issues could prevent your furnace from shutting off, because it’s working to meet your desired temperature when it cannot. Check your temperature setting as well as your air filter. And if that doesn’t resolve the issue, it’s time to give our pros a call.
