Resetting your furnace every once in a while is little more than a mild inconvenience. However, if you ask, “Why do I have to keep resetting my furnace?” you should look more closely at what could cause the problem. After all, you want to avoid a sudden heat disruption should snowy weather arrive.

The Purpose of the Furnace Reset Button
Most modern furnaces come equipped with reset buttons. These mechanisms are safety features that protect the furnaces from overheating. If your furnace overheats, it could result in tripped breakers or system damage.
You can easily identify the button by its yellow or red color and location in the blower compartment. Now and then, an inconsequential fluke might trip the reset feature. When a furnace regularly shuts down and requires a reset, it needs some extra attention and possibly a checkup from a qualified HVAC technician.
Why Do I Have To Keep Resetting My Furnace?
A reset feature tripping continuously can have myriad reasons behind it. Sometimes, the issue has a simple solution you can tackle on your own. Other times, the problem requires more technical skill from a furnace expert. Find out when to call a professional below.
Low Fuel Supply
First, determine whether your furnace’s fuel levels cause your tripping reset button. Your furnace can’t keep up with your heating demands without sufficient fuel. You can simply call your supply company for a top-up under most circumstances.
However, your furnace may also have a dangerous fuel leak. If you recently refilled your gas, propane, or oil reserves, contact an HVAC company for emergency services. Leaks are dangerous for you, your property, and your neighborhood.
Clogged Valves
If you have plenty of fuel and don’t have a leak, you may need to unclog your valves. Fuel travels through the gas valve to provide your furnace with energy. When it meets a blockage, it takes longer to get to your furnace, resulting in symptoms that resemble a low fuel supply.
Overheating Components
“Why do I have to keep resetting my furnace despite having unclogged valves and plenty of fuel?” you ask as the frustration builds.
As we discussed above, the reset feature’s primary purpose is to prevent the furnace from overheating. When components become too hot, they’ll trigger a system shutdown. Some common — and fixable — reasons for an overheating furnace include:
- Filthy filters: Can you remember when you last changed your furnace filter? If not, you should switch it out as soon as you can! Clogged filters prevent proper airflow from circulating throughout your HVAC system, causing your furnace to overheat.
- Closed vents: Check each vent throughout your home to ensure air flows through each grate. Like old filters, closed vents inhibit ideal airflow.
- Vent blockages: Placing furniture and other large objects on top or in front of vents may cause your furnace to overheat. Inspect vent locations and remove any items obstructing the vents.
- Mechanical failures: Furnace fans and connected components may fail and cause overheating. Promptly contact an HVAC professional. Otherwise, you could end up with mounting expenses alongside reset inconveniences.
Dirty Components
Your flame sensor and pilot light operate in a grimy, ashy area. The flame sensor detects the pilot light’s flame and prevents gas buildup. The pilot light ignites the furnace, allowing warm air to circulate through your home.
If either of these parts becomes coated in dust, they’ll trigger a system shutdown. A furnace technician can quickly and easily clean and reattach them.
Thermostat Wiring
Your thermostat could also trip your furnace’s reset feature. The thermostat sends messages about the ambient temperature in your home. When the temperature dips below your setting, the thermostat communicates that the area needs warmth.
First, check the batteries in your thermostat to ensure it has a sufficient power supply. If the problem continues, it could indicate disconnected or damaged electrical wiring. When thermostats have electrical failures, they may send the wrong signals to their connected furnaces.
