Why Does My Furnace Keep Turning On and Off?

Furnace Keep Turning On and Off

The furnace keeps turning on and off. It can be caused by various factors, including dirty filters, a faulty thermostat, or a problem with the blower motor. Short cycling puts extra strain on the furnace and can result in higher energy bills, so diagnosing and repairing the problem as soon as possible is essential. One way to prevent short cycling is to ensure the furnace filter is cleaned and replaced regularly. If the filter is dirty, it can restrict airflow and cause the furnace to overheat. If you need furnace replacement in San Jose, call the professional.

Sometimes, short cycling may also be caused by a faulty thermostat. It may turn the furnace off before it has reached its desired temperature. A professional HVAC technician can test the thermostat and make any necessary adjustments. Finally, a problem with the blower motor can also cause short cycling. If the motor is defective, it may turn off prematurely or run slower than usual. A technician can inspect the engine and replace it if necessary. You can help prevent your furnace from short-cycling by troubleshooting and addressing potential problems.

How Can We Fix It?

We see during the winter furnaces that keep turning on and off. There are a few reasons this might be happening, but the most likely cause is that your furnace is too low. The furnace will run until the house reaches the desired temperature, and then it will turn off. But if the ambient temperature outside is lower than what you have set for the furnace, the house will quickly cool down again, and the furnace will kick back on.

To fix this, raise the temperature on your thermostat until the furnace runs less frequently. Next, check your furnace or a dirty filter leading to more frequent cycling. Lastly, ensure that all doors and windows are properly sealed to prevent heat from escaping. In case you need furnace repair in Palo Alto, visit the website.
