Does your gas heating system keep shutting down randomly, leaving you wondering, “Why do I have to keep resetting my furnace?” The answer might not be as straightforward as you think. In fact, several factors could cause your furnace to turn off without warning, resulting in the need for a system reset.
Our HVAC technicians at Triple A AC, Heating, & Plumbing offer some of the best furnace repair services in Carrollton, TX. We know the frustration of needing to reset a furnace constantly. Our guide below explains the likely reasons for this issue and how to proceed.
How To Reset a Furnace
Resetting a furnace in your Carrollton home or business is relatively simple, but the process depends on the system’s age. You can reset your modern heating systems simply by turning off their power. Flip their circuit breaker switch or press the power button, and then leave the power off for ten seconds before turning everything back on.
A gas furnace over 30 years old may require a few more steps to reset. Try the following:
- Is the pilot light off?
- Turn the thermostat down to its lowest setting for safety.
- Manually ignite the pilot light using a lighter or match.
- Adjust the thermostat to your desired temperature to trigger the furnace’s operations.
Why Do Furnaces Stop Working Suddenly in Carrollton?
Why do I have to keep resetting my furnace? Here are possible explanations if you’re in Carrollton, Texas.
Faulty Flame Sensor
Flame sensors are gas furnace components that ensure the gas valve only opens when the pilot light is on. It’s a safety feature that keeps the gas valve closed unless it senses heat from the pilot light or burners. This mechanism prevents harmful gas from building up inside the heating system or leaking out to affect your health.
Because it’s a safety component, furnaces won’t turn on if a flame sensor sustains damage. Excessive dirt and grime covering the sensor can also cause a similar ordeal.
Clogged Air Filter
Air filters are important HVAC components that trap dust, dirt, and other allergens and contaminants, keeping them out of the indoor air whenever your furnace is on. The filters help improve indoor air quality while keeping airborne particles from settling around internal heating system components. However, air filters get dirty and need periodic replacement.
Leaving a clogged filter in place for too long will restrict much-needed airflow from the furnace, and the system will overwork itself to compensate for the loss. Do you notice an unusual amount of dust settling around your home or air that seems stale lately? If you find yourself constantly resetting your furnace, it might be beyond time to replace the unit’s filter.
Overheating Furnace
Another common consequence of leaving dirty air filters inside furnaces is overheating. The airflow restriction can cause the heating unit’s internal temperatures to rise dangerously, prompting the system’s safety features to shut everything down.
Why do I have to keep resetting my furnace? If your system seems to be overworking itself and overheating as a result, check the filter is clean and that nothing is blocking the return vent that houses the air filter. If everything appears to be in order there, double-check your thermostat settings, as temperatures that are too high or low will also cause overheating.
Insufficient Fuel
Sometimes, gas furnaces don’t receive enough fuel to function properly. These complex systems need a certain amount of fuel to initiate the combustion process and generate heat. Problems that could result in insufficient furnace fuel, like a gas leak or issues with the local gas company servicing Carrollton residences, can see a furnace producing insufficient heat or none at all.
A fuel injection problem might seem small, but if these issues stem from a gas leak, there’s a real danger of potential carbon monoxide poisoning. Even if no leak appears to be present, running your heating system without enough gas feeding into it can eventually cause ignition failure. It’s best to resolve this problem quickly.
