Trouble with your heater can stem from any number of issues, but you should know, the problem isn’t always an expensive concern. Sometimes it’s as simple as a dirty filter or a faulty thermostat, both of which can be fixed with minimal effort and cost. You probably assume the problem is bigger because it’s causing you monumental problems. Still, there could be a simple answer to your question, especially if you’re wondering why does my heater keep shutting off?
Your heater sounds like it’s probably cycling off too soon, which is a common issue for furnaces. The early cycling off could be due to one of many reasons: a dirty filter, a faulty thermostat, a corroded flame sensor, foreign objects lodged in the air vents or chimney or a heating system not properly sized for the area being heated. It’s important that the homeowner has had all these elements checked out before the cold season arrives.
The easiest of these elements to correct is the dirty filter. The filter should be replaced if it is dirty. The dirty filter is preventing the heater from reading the correct temperature in the home. The furnace is assuming its warm already and the heater cycles off. After the dirty filter is replaced with a clean one, the furnace can read the actual temperature and it will continue running until the house reaches the desired temperature.
Another common problem is the heating system not having the proper rating for the space it must heat. You may ask, “How are heaters rated?” Heaters are rated based on the number of British Thermal Units needed to heat a space. But, this is not the only issue for determining the heater needed for a specific space. You should hire a professional to make that judgment because many factors are used to calculate your heating unit’s size. The factors considered are square footage of your home, the layout of your home, how your home is constructed, window number and type, insulation, exterior materials and the climate of the region. The rating of your heater is important, but it’s more important for it to be the right sized unit.
