Tripped Breakers And Common Heating Blower Issues

If you've been running your heater non-stop this winter, then you may be experiencing some issues with the appliance. One common issue develops when the heater continually trips a circuit breaker, keeping the unit from running and producing heat. If this is happening to you, then you should contact your heating repair specialist as soon as possible. Keep reading to learn about a few common blower issues that may be causing this problem.

Overheating Blower Motor

One of the most common causes of a tripped heating breaker involves the overheating of the blower motor. If you notice that your breaker often trips when the blower has been running for a period of time, then this may be your issue. 

The blower motor tends to create a good deal of heat and a properly working heating system will allow for good airflow to reduce this heat. Sometimes a clog in the system will trap the hot air close to the blower motor, causing it to overload. In this case, the breaker is tripping to prevent a full burnout of the motor and to prevent a fire. 

Oftentimes, an overheating blower can be rectified by changing the furnace filter and by clearing debris out of the exterior air supply vent. However, if the motor has been overheating for months, then the motor should be inspected for heat damage. Also, the attached breaker may need to be changed, as breakers can become weak if they are constantly tripping. 

Overworked Blower

An overworked blower may also be the reason for the breaker tripping. In this case, the blower is again producing a great deal of heat, but this is due to normal functioning and extended fan activation. The overworked blower may be caused by a poorly sized heating unit for the home. You should speak with a heating professional to see if a larger one is suggested or if a bigger blower motor can be installed.

If you've had your heating system for some time, then the constant activation may be due to a leak in the ductwork and the inability of the heater to keep up with demand.

The thermostat connected to the unit may also be broken and activating the fan when it is not needed. If you notice that the fan continues to run well after your home has reached the desired temperature, then this is likely the problem.
