Your gas furnace should usually be turned on and off 3-8 times hourly for making the temperature at home nice. However, a furnace that shuts off every minute or two would not properly heat your home. It does not only signal a huge concern that you have to take care of. This is a serious concern that needs to be repaired immediately. But please don’t lie down and shiver. Fix the problem by calling a Furnace repair in Toronto or learning how to fix the furnace.

When the Furnace Airflow Is Blocked
The heat exchanger in your furnace needs a strong airflow to cool it off. The heat exchanger may overheat when the airflow is hampered, prompting a safety halt. This covers your furnace but leaves you cold. Thankfully, it’s easy to solve.
Change the Filter
Over time, debris and dust obstruct the furnace air filter, which limits airflow to the furnace. All you have to do is change or clean the filter when you see your filter is blocked.
Modify a Disposable Filter
Replacements are affordable and easy to obtain, so stock on a few substitutes. Clean a filter for reusable. This is of better quality but needs to be washed regularly. Rinse the dirt off and/or rinse softly.
Check Your Thermostat
The thermostat may be another cause of the furnace’s shutting off.
Check the Setting
Ensure that your thermostat is activated and set to ‘HEAT.’ Someone could change it to a lower temperature than you would prefer, so check the temperature settings.
Test the thermostat functioning with the Furnace
Take a friend close the furnace and ask them to listen when you are adjusting the thermostat from “LOW” to “HIGH.” Whether he or she detects a sound, presumably there is an issue with your furnace. If not, your thermostat may fail.
Check the Flame Sensor
A flame sensor could be a reason for your furnace’s shutting off. The flame sensor is designed to turn off your furnace and to safeguarding you against harmful gas fume when no flames are observed. If the flame sensor becomes corroded or covered in soot, flames cannot be detected, although the furnace works correctly. Resulting in, the furnace is then shut down by the sensor.
The Furnace Is Too Big
A furnace that may too big for your home may have been sold to you. If so, your rooms are heated easily. When the furnace hits the fixed temperature, the thermostat shuts it off and causes the house to instantly cool.
