The furnace or the cooling system is essential to every household. Its proper functioning is even more crucial. To maintain the desired temperature, the normal cycle of the furnace is about 3 to 8 times per hour. If the furnace is constantly shutting off and starting, then there are a lot of issues that might arise. This way, it will not produce enough heat to warm up the house. In such a case, you need to reach out to the experts to carry out an inspection and figure out the reasons. The experts at Air Makers are well versed in the functioning of a furnace. They will diagnose the issue and help to figure out a solution. Following are some of the possible reasons why this might be happening
Clogged Filter
When the filer in the heat exchanger is blocked, it restricts the airflow. This restriction then causes overheating leads to a safety shut down. One of the ways to prevent this is by cleaning out or changing the filters. The filters need to be cleaned once every three months or per the manufacturer’s recommendations. Meanwhile, also inspect the air vents. Closed air vents can hinder the air from reaching the room by hindering the airflow to the furnace. One of the best solutions is to have disposable filters.
Malfunctioning Thermostat
The thermostat is an essential element of a furnace. It communicates the desired actions like the temperature or turning it off and on to the furnace. The settings and sensors make it easier to control the room’s temperature. When the furnace is constantly shutting off, you also need to check the thermostat. Check whether the settings are on the HEAT status. Ensure that the temperature is not lower than your preference. While listening to the furnace, you can turn the thermostat from low to high. If there is sound, then there is some issue with the furnace. It requires repair. Otherwise, it is the thermostat that is not working correctly.
You can also try changing the position of the thermostat. Ensure that it is not close to any direct source of heat. When the thermostat is close to direct heat, it will send a signal to the furnace that the room is too hot. This will switch off the furnace without heating up the house. The placement of the thermostat is crucial. It should be at least 1.5m high and not close to drafty doors and windows.
Incorrect Furnace Size
Incorrect furnace size could be another reason why the constant shutting off is happening. The size of the furnace is determined by the size of the room or house it is heating. If the furnace provides too little or too much heat, it will cause the thermostat to read the temperature in the room and shut the furnace off. Once the room cools, it will turn on again. This time the cycle would be short. This process can take a toll on the furnace and also make you feel uncomfortable through the process.
