Why Does My Furnace Keep Turning Off?

A furnace can suffer from short cycling, which means frequently turning off. It generally happens due to a lack of maintenance. However, there could be several more reasons behind this issue. Short cycling of the furnace during winters is extremely uncomfortable even to imagine.

You should detect the issue in the starting and consult for help before it turns into massive trouble for your family in winters.

4 Reasons Behind Furnace Short Cycling

There are a few reasons as to why your furnace keeps turning off. If any of the below reasons persists, check for furnace repair near you to mitigate the damages.

  • The Size of the Heating Unit

If your heating unit is too big for the space it is heating; it will turn off rapidly. It occurs because the large unit will heat your place quickly and shut down as soon as it reaches the required temperature. Initially, it appears good, but it will affect the efficiency of your unit with time. It will also cause frequent wear and tear of the parts. 

Thus, if you detect any such defect in your heating unit, contact your HVAC contractor of furnace installation in Lynnwood and schedule a tune-up as soon as possible. 

  • A Defective Thermostat

A programmable thermostat controls the cycling of your furnace automatically. If your furnace is turning off repeatedly, check the thermostat. A faulty or broken thermostat can be the reason behind this problem. Frequent and extreme fluctuations in the temperature also affect the action of a thermostat. 

Make sure that the thermostat should not be installed in direct sunlight. Change the batteries of the thermostat and check. If the issue persists, look for furnace maintenance near you for thermostat repair or replacement. 

  • Insufficient Airflow

Low airflow can also turn your heating system off. It is an inbuilt safety measure of heating units that prevents them from overheating. Thus, you need to detect the cause of low airflow and fix it. It can be due to dirty air filters, blocked air vents, or a faulty blower wheel. 

You should clean and replace the air filters regularly to avoid this situation. You should also check the air vents and return registers for any clogs and clean them. Ensure to turn off the power supply before inspecting the blower wheel or fan. Get in touch with an HVAC contractor of furnace installation and let the professionals check the system. 

  • Faulty Pressure Switch

A defective pressure switch is another reason for frequent turning off and on of your heating unit. If you have a multimeter in your heating unit, that will help find the cause.
