A furnace reset button is usually found inside the blower chamber of the furnace unit. The red or yellow color in which it is frequently exhibited makes it easy to spot. A reset button’s primary function is to serve as a safety feature. It aids with the shutting down of the furnace when it becomes too hot. This effectively prevents the circuit breaker from being tripped by the hot furnace. However, if such a tripping-off situation arises, again and again, you may consider the best HVAC services, including heating repair in Frisco.
A furnace may need to be reset from time to time, for example, if it becomes excessively hot. The reset button comes in handy in this situation. On the other hand, if your furnace keeps resetting, the reset button is likely being activated by a problem. Here are a few things that can be concluded as a reason for this tripping off.
Possible Reasons For The Furnace Reset Button To Be Triggered
If your furnace keeps resetting, it’s time to figure out what’s causing the reset button to trip. Here are a few possible causes.
This is the most common reason for the reset button to be triggered. If your furnace is tucked away where there isn’t adequate airflow, it may overheat regularly. This results in many excursions to the reset button.
2. There is no Fuel
The reset button on your furnace may be triggered when it runs out of fuel, whether it’s oil or gas. A brief inspection of the gasoline tank will reveal whether the problem is due to a fuel shortage. If it is, the tank can be refilled.
3. Dusty Filter
The air filter in your HVAC system is quite important. When your furnace warms up your house, it draws air through this filter. Dust, grime, and other particles are trapped in the air filter, preventing them from entering the furnace unit. As a result, over time, the filter may become blocked. The furnace reset button might also be triggered by a blocked air filter. It’s as simple as replacing or cleaning the air filter to fix this.
4. Gas Valves That Are Blocked
When a gas valve linked to the furnace is turned off, either purposefully or unintentionally, the fuel supply to the furnace is cut off. As a result, the reset button will keep tripping until the valve is closed. When you have an issue like this, you should examine the gas valves.
5. Problems With Flame Sensors Overtime
Dirt and debris can accumulate on the flame sensor of your furnace unit. This stops the sensor from working properly, which causes the reset button to stop working as well.
Manual Resetting a Furnace
There are instances when you will need to reset a gas furnace manually. To do so, turn off the pilot light, set the thermostat to the lowest setting, and disconnect the furnace’s electricity and gas supplies. Then hold a lighted match to the pilot flame’s aperture. Reconnect the furnace’s power and gas supply once the pilot flame has been lit. Finally, for 30 seconds, press and hold the reset button.
