Signs of an Overheating Furnace
Overheating events can be dangerous, so quickly recognizing the signs of trouble is critical. Turn the unit off at the first sign of a malfunction. Be on the lookout for:
1. A Burnt Smell
Sometimes, units that sit idle for a while emit a burnt, musty smell when turned on, but this should dissipate quickly. If the scent lingers for more than half an hour or grows stronger, something isn’t working right. Strong burnt smells usually indicate an overworked component, such as the motor.
2. Strange Noises
A low humming noise from your furnace is normal. However, new or sudden sounds such as clanging, banging, or thumping can signal trouble. These noises often occur when internal parts begin to wear down or fail, which can lead to overheating. If your furnace starts making odd noises, it’s time to call for professional furnace repair.
3. Unexpected Shutdown
If the system powers off suddenly, it may be due to overheating. Modern furnace safety sensors will trip when the temperature exceeds a safe threshold. This causes a soft lockout when the unit powers down until it’s safe to run again.
After multiple soft lockouts, the unit will shut down into a hard lockout, which requires a professional to reset the control board. To prevent a hard lockout or further damage, it’s best to contact a heating service immediately after the unit shuts down.
Common Causes of Overheating Furnaces in Arrington, TN
Furnaces can overheat for various reasons, but some of the most common relate to improper maintenance. When components become dirty or clogged with dust, they restrict airflow to the unit. By regularly changing your air filter and investing in annual inspections, you can keep most such problems at bay.
A professional will also check for other contributors to poor airflow, such as wear and tear on the fan blades or a stressed motor. The technician will also look for electrical issues and worn-out parts to determine whether your system is approaching the end of its useful life.
Often, short cycling is the hidden cause of overheating. This is when your unit fails to complete an entire heating cycle because of a mechanical issue. It will start up and turn off frequently, stressing the motor.
If you notice short cycling, request a professional inspection immediately; don’t wait for the system to overheat and require more extensive repair.
Why an Overheating Furnace Is Dangerous
An overheating furnace puts you at risk for serious hazards, like gas leaks and furnace fires. While automatic shutoffs exist to prevent these events, they can rarely occur when heat stress cracks parts of the heating system.
Beyond the safety risk, overheating stresses your unit more than necessary. The additional wear and tear leads to more expensive repairs and shortens the life of your system.
These symptoms also indicate that your unit is not working efficiently. An underperforming unit will not heat your home as comfortably or consistently, and your energy bill will often increase.
Turn your furnace off immediately at the first sign of overheating. If you’re worried about a possible gas leak, turn off your home’s external gas valve and evacuate.
Contact a professional heat service to diagnose and repair the issue. DIY repairs are dangerous and often lead to poor results. Heating experts have the expertise and tools to access parts of the system you can’t, so they can be certain about the root cause of overheating.
