What Causes a Heater to Stop Working?


If you could prevent problems in your life before they start, you would probably take every measure you could to stay ahead of trouble. Unfortunately, it’s not always that easy. While it doesn’t get too cold down here in Texas, we do want our heaters working perfectly when the colder days arrive. And thankfully, heater problems fall on the list of things you can stay ahead of. 

You can’t prevent all heater problems, but you can invest in heater repair in Frisco, TX to stay ahead of most of them this season. In fact, heater maintenance is a great way to stay ahead of issues for years to come. But you need to know what signs to watch out for. Learn more about what causes your heater to stop working so you can prevent problems before they begin. 

Check Your Thermostat

No matter what type of thermostat you have, it can cause problems. Make sure that the thermostat settings are correct. It’s possible that your heater problems are really thermostat problems, which can include:

  • Low batteries
  • Reading the temperature incorrectly
  • Not communicating with your heater
  • Not changing the temperature at times you’ve programmed

Thankfully, these are all easy problems to troubleshoot when you call a professional. 

Check the Power Source

Your heater is connected to a circuit in your home. If too much power surges through the system on that single circuit, it’ll trip and disconnect power to anything connected. If your heater won’t turn on, check your circuit breaker panel and find the one for your heater. It could be in the “off” position, and if so, you need to switch it back on. 

Keep in mind that your heater’s circuit should not switch off frequently. If you find yourself constantly turning the breaker back on, that’s a problem. You may need to have that circuit replaced with one that is larger and can handle the load of your heater. It’s also possible that something is wrong with your heater connection that is causing power to surge through. A professional can fix the problem.

Replace the Air Filters

One of the easiest ways to mess up your heater is to forget to replace the air filter. Dust and dirt may be small particles, but over time they can wreak havoc on your heating system. Waiting until the filter is full means that dirt is escaping through the filter and into your heater. Instead, change the filter on time, every time. And if the filter looks particularly dirty, change it even sooner. 

Check for Drainage Problems

If your heater has a drainage problem, the condensation pan can fill up and not empty out as it should. When it gets completely full, your heater will shut off as a protective measure. If the condensation pan is full, you should check the reservoir pan next, and finally the drainage line. If both pans are full, there is likely a blockage that is preventing the system from draining as it should. Our team can empty both pans, clear out the drainage line, and then talk to you about steps for preventing a blockage in the future.
