Why Do I Have To Keep Resetting My Furnace?

Why do I have to keep resetting my furnace when there’s nothing else wrong with it? A reliable furnace will help to maintain a comfortable temperature in your home as the weather cools. In fact, an energy-efficient furnace can last well over a decade with regular maintenance, so it’s understandable that quirks like resetting itself may become frustrating.
Have you been waking up every night shivering only to discover that your furnace isn’t running? Unfortunately, this isn’t an issue to ignore. The unit may have damage that requires service from a licensed professional.
Below, Coral Springs’ reliable heating maintenance technicians from Lion Air Conditioning Cooling And Heating, LLC, explain why the furnace might be resetting.
Overburdened Air Filter
Your furnace has an air filter that removes dust particles, mold spores, and other contaminants from the air. Have you replaced the air filter in the past three months? If not, that could be why your furnace keeps switching off unexpectedly.
A furnace trying to operate with a dirty air filter is less efficient and will eventually break down. Cleaning the filter should get the heating back on track.
If your furnace has poor airflow, the internal temperature could climb to dangerous levels, overheat, and switch off. If your air filter is clean, check the thermostat settings. A temperature set too high or too low will cause your furnace to overwork and overheat.
Not Enough Fuel
Gas furnaces need a steady gas supply to operate normally and avoid ignition failure. If your furnace runs out of fuel, it may switch off to avoid a safety hazard. Check your unit for signs of a gas leak, and be sure to install a carbon monoxide alarm near your furnace.
Worn or Dirty Gas Valves
Your furnace has gas valves that open and allow air to flow through your furnace, creating warm air to heat your home. If the valves don’t open for some reason, your furnace may turn off. It might be too much dirt on the valves or normal wear and tear.
Damaged Flame Sensor
Why do I have to keep resetting my furnace? It could be your furnace’s flame sensor rod. Normally, it detects when the burner produces a flame and continues the heat cycle, but it will switch off if there’s a sensor issue.
Steps to Avoid Resetting Your Furnace
Sometimes, a small problem can reset the furnace; you just have to know where to look. Thankfully, if your furnace reset button keeps popping up and you’re unsure why, there are a few things it might be. However, experts do not advise poking around your gas furnace for safety purposes; always call a professional.
For example, a team like Lion Air Conditioning Cooling And Heating, LLC will always double-check that the gas furnace is off, close the gas line, and turn off the circuit breakers. With these necessary safety precautions, they will then look at the following:
- Check the filter. Even if it’s not the cause of your furnace resetting, it needs to be clean.
- Secure the door cover. Close the door securely to avoid problems like sensor issues.
- Open the vents. Some people close the vents in rooms that don’t get a lot of use to save money. That’s understandable, but closing too many vents can affect airflow and cause countless issues within the heating system. Opening a few vents could help.
- Examine the thermostat. A damaged thermostat will heat inconsistently. The technician will check for signs of damage and change the batteries.
- Check for damage outside. Anything blocking the outside vent could cause your furnace to stop working. Look around the area and clear away debris wherever possible.
Extend the Life of Your Furnace With HVAC Maintenance
There are several reasons your furnace could malfunction, but the best way to keep your furnace in good shape is by scheduling regular HVAC maintenance. It’s normal for furnace components to wear out after a few years. A service replaces them to extend the life of your furnace and help it to run more efficiently and reliably.
