Furnace flame sensor basics

Many homeowners aren’t familiar with the different components inside their furnaces, which makes it difficult to troubleshoot problems. One furnace component that can cause problems is the flame sensor. The furnace flame sensor is a part that controls the valve that emits gas into the furnace to generate heat. The sensor detects the presence of a flame and closes the gas valve if there is no flame. This sensor plays an essential role in the safety of homes with gas furnaces, so it’s important to make sure the sensor is working as reliably as possible.

The most common furnace flame sensor problems

There are a lot of potential problems that can come up with furnace flame sensors, so it can be difficult to pin down the exact source of a furnace problem. Knowing how to tell if a furnace flame sensor is bad in Mabank, TX can make it a lot easier to get to the bottom of furnace issues and get them resolved as soon as possible. Here are some tips for how to identify and address a few of the most common furnace flame sensor issues in Mabank, TX:

  • Furnace short cycling: One of the most common signs of a furnace flame sensor problem is short cycling. With short cycling, the furnace turns on and lights up, but then shuts down after just a few minutes of running. If this problem is happening with your furnace, it might be caused by a flame sensor that’s cracked, corroded or damaged in some way.
  • Dirty flame sensor: If your flame sensor appears dirty and covered with a sooty residue, it likely won’t operate as effectively as it should. It’s possible to clean a flame sensor by shutting off the power to the furnace, removing the flame sensor and using an emery cloth to clear away the residue.
  • Cracked or damaged flame sensor: Another one of the most common furnace flame sensor issues in Mabank, TX is cracking and damage. When a furnace flame sensor becomes cracked or damaged, it will likely cause short cycling and other furnace problems. The best way to deal with this is to have the part inspected by a professional HVAC technician, and replaced if necessary.
