7 Ways to Troubleshoot A Malfunctioning Furnace

We all enjoy the warmth and comfort of a furnace’s heat after a long, cold day outside. However, a malfunctioning furnace sounds like an absolute nightmare, especially when the city is covered in snow.

While there can be many reasons behind a malfunctioning furnace, in most cases, you need to call a professional furnace repair in Bowling Green. However, here are some easy ways to troubleshoot minor problems on your own.

7 Quick Troubleshooting Tips for a Malfunctioning Furnace

  1. Inspect the Circuit Breaker

If the furnace won’t turn on, the circuit breaker or fuse might be tripped or blown. Circuit breaker panels are usually located in areas like the garage, laundry room, or storage area. Locate and open the panel to inspect the circuit controlling your furnace. 

If adjusting circuits and switches does not resolve the issue, the electrical wiring in the circuit may be malfunctioning. In such a case, call a professional furnace repair near me.

  1. Check the Electronic Ignition System. 

Most modern furnaces include an electronic control system. It is responsible for providing superior performance and also helps conserve energy. Inspect the system for damaged pilot lights, broken gas burners, or gas leaks. Gas leaks can be potentially dangerous; thus, you need to call for repair right away!

  1. Check on the Safety Switch

A safety switch is usually located near the furnace door, which you can use to deactivate the combustion process and fan if you remove the front panel. If this safety switch has worn down or has reached the end of its lifespan, get it replaced and lookup heat pump installation near me.

  1. Observe the Flame Burner

When dirt and debris accumulate in burners, the furnace will struggle to produce heat. If you see that burners produce yellow flames instead of blue, it indicates that it needs to be cleaned by a professional. 

  1. Check the Furnace Limit Switch

A limit switch that includes a sensor is activated to ensure uniform circulation of warm air throughout your house. This sensor is usually located in the heat exchanger of the gas furnace that ensures the ambient temperature of the air before being pushed out from the filters. 

  1.  Clean the Flame Sensor

A clean flame sensor is necessary to ensure its ability to detect and monitor the flames produced accurately. The best way to clean the sensor is to navigate and remove it from the system first. Cleaning it while it is installed can cause damage to the surrounding internal parts of the furnace.

However, if you are finding the whole process tricky, leave it to a professional furnace repair near me.

  1. Clean The Air Filters

Short cycling can be a sign of a clogged or dirty air filter. We recommend turning off the furnace and cleaning the air filter. In some cases, it can require a filter replacement.
