For safe, reliable heating system performance throughout winter, following a maintenance plan is essential. For instance, airflow through the heat exchanger is reduced when the filter is clogged, and the equipment could overheat and break down as a result. The same is true when the furnace blower wheel is caked in grime. To describe the problem to a furnace repair specialist so they can better assist, below are a few troubling indications of overheating. 

3 Signs Your Furnace Is Too Hot

1. Short Cycling

When overheated, the furnace could start to short cycle. This means it cuts off before a heating cycle is complete. If the airflow is restricted, heat becomes trapped in the appliance. Safety mechanisms sense the temperature rise and shut the system off before mechanical components are affected. Clearing areas around interior vents should solve the problem. Otherwise, a furnace repair technician can change the air filter or clear blockages in the exhaust pipe to prevent heat buildup.

2. Burning Smell

A burning stench wafting through the house is an immediate cause for concern. Shut down equipment and call a furnace repair technician to investigate. When the circuit board or fan motor overheat, for example, the associated smell is reminiscent of gunpowder. If the safety mechanism fails to shut off the appliance, you might get whiffs of a burning smell as it overheats. 

3. Loud Commotion 

When the motor is failing, heat will accumulate inside the furnace. Until it finally goes out, the motor will work harder to function properly. The strain could cause a noticeable clanging noise.
