Your top priority in the winter is keeping your furnace running smoothly. Homeowners often experience furnace blower motors that will not fire. Poor heating and winter discomfort can result.
Let’s explore the causes of your furnace blower motor not working and offer troubleshooting tips. Contact an expert for furnace repair in Brooklyn and Queens for experienced help.
Understanding the Furnace Blower Motor
Your furnace’s blower motor is crucial. A smoothly running blower motor means your home receives adequate warm air. The blower motor activates to supply sufficient heat to keep your thermostat running. If the blower motor breaks, your home can be cold, and your energy costs will escalate.
Common Causes of Furnace Blower Motor Failure
Thermostat Issues:
The thermostat is the core of your heating system’s functionality. If it malfunctions or is misconfigured, it may not start the blower motor. Make sure the thermostat is set to “heat” and higher than the room temperature.
Power Supply Problems:
Without power, the furnace’s blower motor will not work. Check your circuit breaker for tripping or blown fuses. If the power goes out, reset the breaker or replace the fuse.
Blower Motor Failure:
The blower motor may fail due to age or negligence. If it makes strange noises or runs hot, replacement may be needed.
Capacitor Issues:
The capacitor starts the first energy zap to start the blower motor. Should the motor fail from capacitor action? A bulging or leaky capacitor casing indicates damage.
Grime Filters:
Blocked air filters cause blower motor overheating and stoppage. Replace or clean air filters regularly to avoid this issue.
Limit Switch Issues:
The limit switch monitors the furnace’s interior temperature. If the furnace overheats, it turns off the blower motor to prevent issues. A faulty limit switch can impede the blower motor’s startup.
Furnace Blower Motor Troubleshooting Steps
If your furnace blower motor is not operating, try these fixes before consulting a pro.
Check the thermostat:
Make sure the thermostat works fine. Replace batteries and turn on heating mode if your model uses them.
Check the power:
Check and reset the circuit breaker. Examine the power cord damage and that the furnace is on.
View the Blower Motor:
If you are comfortable doing so, inspect the blower motor for wear and damage. If it appears scorched or damaged, replacement is the best option.
Test the Capacitor:
Check the capacitor for continuity with a multimeter. It must be replaced if defective.
Change Air Filter:
Change your air filter if you have not recently. A clean filter improves airflow and prevents overheating.
Check the Limit Switch:
If you suspect the limit switch is broken, call a professional specializing in furnace repair in Brooklyn and Queens. The component can be tricky to identify and replace.
