The function of a furnace’s reset button is to shut it down before it trips your circuit breaker. The reset button on your furnace is an easy way to address any short-term problems. However, if your furnace continually shuts down and resets, it indicates a more serious issue. When your reset button appears for the first time, your initial instinct should be to press it.
Troubleshooting Reset Problem
Begin by attempting to reset your furnace once. If you have the same difficulty, the problem might be caused by something that a reset button cannot handle. If you feel compelled to tap it again, do not press it more than twice. Then you need to go through a troubleshooting process to make sure that your furnace works properly. Below are a few troubleshooting steps because of which your furnace might need constant resets:
Turn Off The Furnace
Before beginning the troubleshooting process, turn off the electric supply to your furnace.
Check Fuel Level
Refilling your oil is one of the most difficult things to remember if you are used to a gas furnace. If you utilize propane heating methods, the same rationale applies. Begin by inspecting your oil tank. If it is empty, refill.
Check Flame Sensor
If your reset button pops up, again and again, the flame sensor could be the issue. Flame sensors have an unhealthy habit of getting filthy. It is preferable if you make a routine of inspecting and cleaning your flame sensor every six months. They can be cleaned with anything from a hard brush to steel wool.
Your owner’s handbook may have a different view, so make sure to consult it before cleaning. Checking your burner is also synonymous with checking your flame sensor. While you are there, make sure no dust or rust is surrounding the flame sensor. Anything in this region has the potential to trigger an ignition failure.
If your furnace is unable to breathe, it will be unable to create the air required to ignite. Check the air filter and see if it has turned grey. The filter might need a change. Occasionally, a vacuum can be used to clean the filter. Remove as much dust as possible.
Inspect The Fuel Line
Examine the fuel line. A blocked fuel pipe is a very typical problem with a furnace. Check that none of the valves along your fuel line are closed. Typically, this indicates that the valve is pointing in the incorrect direction. Turn the valve until it is open. The flow should be audible once again. Do not reopen the flow while the furnace is still running; this might result in fuel difficulties.
Check The Thermostat
A thermostat instructs your furnace when to turn on and off. Examine your thermostat to determine if it has any problem codes. If no error codes appear, make sure the thermostat is set to your chosen temperature.
If it is very low, the thermostat will turn off repeatedly. This, however, does not indicate that you should restart your furnace. If adjusting the temperature does not work, clean the surface and the interior. Wires encrusted with muck may not communicate effectively with your furnace.
Check Corrosion And Old Age
Older systems may not age well, resulting in serious problems if not addressed promptly. If your system is older, rust is an indication that it needs to be replaced. Corroded metal might result in an unintentional leak and a hazardous scenario.
If your system is recent, rust may indicate that it has been exposed to too much humidity. Examine the area for any adjacent leaks and fix them if necessary. Consult a technician to discover whether any detailed repairs are required.
