A reset button plays a vital role in avoiding permanent or severe harm done to your furnace thus shutting the system immediately, it provides both safeties and helps you to detect problems to be taken care of.
Perhaps, it may not come to you as often or usually but don’t panic when the system shuts off since the phenomenon is common and your furnace requires occasional resetting. When that happens, make sure to call in the experts to get your system checked.
What causes the reset button to trip?
Your furnace button may be triggered by the following causes or scenarios:
Shortage of fuel
The reset button of your furnace May trip due to a shortage of fuel in your furnace. In case you have an oil or gas furnace, there are chances that your furnace may run out of gas or fuel which eventually triggers the reset button to trip and shut off your furnace.
If this may be the case, then you don’t have much to worry about as these shutdowns are temporary and can be fixed as soon as your furnace gets refilled. If you have called in the experts to look after the matter, make sure you notify them of the fuel shortage and resolve the matter as soon as possible. Once you have successfully refuelled your furnace then you are as good as new and can get your furnace back to running again.
Jammed or Blocked gas valves
Jammed or Blocked gas valves are also responsible for tripping the reset button of your furnace. When the reset button is tripped, consider checking if all the valves are functioning and not blocked. These are unusual but possible cases of tripping the reset button of your furnace. Therefore, ensure to check the valves whenever your reset button trips.
Overheating of Furnaces also triggers the reset button to trip and shut off your furnace. This event may occur when your furnace is not receiving adequate air flow thus overheating it. Therefore, ensure to check the air filters and the vents to ensure there is proper airflow. Make it a habit to check the air filters and take necessary actions if needing to clean or replace them with a completely new set.
Faulty Flame Sensor
A however unusual but also possible cause for your furnace reset button to trip is the work of a faulty flame sensor. The flame sensor rod may be malfunctioning due to the accumulation of dirt and debris making the furnace inefficient and leading to the shutdown. Ensure keeping your flame sensor clean by avoiding the accumulation of dirt and debris.
Dirty Air Filters
One of the common causes of your furnace breakdown or shutdown can be because of dirty air filters. Ensure checking your air filters and consider changing them quarterly for better results. Accumulation of dirt and debris in the Air Filters of your HVAC system may lead to a unit breakdown.
