It is a normal scenario for heating systems to cycle on and off several times an hour. However, when your furnace is shutting off much more often than usual, that triggers concerns about proper functioning of the appliance. Let's have a look at the top reasons why your Lennox Furnace Repeatedly Stops and Starts.
If your air filter clogs with dirt, the airflow to the heat exchanger becomes restricted and the component overheats. This, in turn, triggers the high limit switch (your safety shutoff). To solve this problem, just turn off the furnace and change the filter, if you have the disposable type. Permanent filters, which do a better job of protecting your furnace and are more eco-friendly, are designed to be cleaned and reused.
Check your thermostat to determine if it is turned on. Make sure it’s switched to “HEAT” and set at the correct temperature. (If the temperature setting is too low, your furnace will shut off more frequently than you’d like.)
Consider thermostat location as well. Ensure it isn’t mounted too high because, as you may remember from science class, hot air rises. If the thermostat registers extreme temperatures, a shortened furnace cycle may result.
