Reasons Why Your Furnace Keeps Shutting Off
You turn on your furnace. It runs for a few minutes, and then it shuts off. Later on, it turns back on and the cycle continues. Does this sound familiar?
A furnace that constantly turns on and off should not be taken lightly and the problem should be addressed immediately. Otherwise, it can cause serious damage to the equipment, leading to expensive repairs and premature breakdown.
Here are 3 of the most common reasons why your furnace keeps shutting off.
Furnace is too big for your home
Getting the right furnace size for your home is important to maintain a better heat flow throughout your home. An oversized furnace will heat your home quickly and then shut off. Once it senses that the air is too cold, it will turn on again and start heating your home. This may cause your heating system to breakdown prematurely.
Furnaces are like shoes. You need to get the right size or it will fail to keep you comfortable in winter.

Sometimes, a faulty thermostat may be the cause of the problem. Before assuming that your heating equipment needs repair, make sure that the thermostat is turned on and set to the accurate setting.
The placement of your thermostat may also be a cause of short cycling. If it is close to another heat source such as a heat register or direct sunlight, it could sense that your home is too warm. When this happens, your heating system will shut off.
Dirty air filter
A lot of people fail to realize this, but a dirty or clogged air filter is one of the main causes of short cycling. It restricts air from getting into your furnace and the blower will struggle to pull in enough air over the heat exchanger. Due to the lack of airflow, the heat exchanger can get too hot. When this happens, it trips the high limit switch and the furnace shuts down. To prevent this problem, be sure to check your air filters every month and change it when it’s dirty.
