Troubleshooting Tips for Home Furnace Blower Problems

Troubleshooting Tips for Home Furnace Blower Problems Home furnace blower problems are a common occurrence around this time of the year. If your furnace isn’t keeping you warm, the following tips can help you pinpoint the problem:

  • Check your thermostat settings. You can see if your thermostat is working by setting it 3 to 5 degrees warmer than room temperature. If it’s working properly, the furnace should kick on immediately.
  • Check the circuit breaker. Electrical storms, snow storms and heavy winds can trip breakers. If you’ve experienced a recent power outage, check your breaker to ensure it hasn’t tripped.
  • Inspect the filters. Dirty and clogged filters can block the flow of oxygen into your furnace, which can cause your unit to malfunction and shut itself off. If it’s clogged, change the filter and see if that resolves the problem.
  • Reset the furnace. Be sure to follow your owner’s manual carefully. These steps are simple, but you’ll want to do them in the correct order to avoid damaging your furnace.
  • Inspect the pilot light. If your furnace is blowing cold air, the problem could be as simple as a blown out pilot light. If your pilot light is out, relight it and eliminate the draft that’s blowing it out.
  • Check the gas valve. The gas valve should be inline with the pipe. If it has been bumped, it’s possible the gas supply has been shut off.
  • Test the blower. Close your furnace door and turn the circuit breaker for the furnace off. Once electricity has been shut off, inspect the blower motor’s belt. Make sure it is not frayed, cracked, or unduly worn. If it is, replace it immediately. If the blower is hot when you inspect it, this may indicate an overheating problem, which requires a professional replacement of the motor.
