Why isn’t my furnace working?

The weather is starting to get cool (finally).  Nothing is worse than turning the furnace on and realize nothing is happening.  Here are some troubleshooters for you:
Your furnace is running but isn’t providing enough heat:

  • Be sure nothing is blocking the flow of warm air
  • Set the thermostat to “heat” and the fan to “on or auto”. Raise the temperature by 5 degrees and see what happens
  • Check your filter. Most people to forget to replace it when it is dirty and reduces efficiency
  • If you have a gas furnace, be sure the valve on the gas pipe is turned on – the handle should be in line with the gas pipe and check the fuel supply.
  • Make sure the furnace’s circuit breaker is on or that its fuse has not blown
  • The motor may need to be reset because of an overload. Press it and wait 30 seconds.
  • If the furnace still doesn’t work, be sure the thermostat isn’t faulty.

General Maintenance:

  • Vacuum out the area around the furnace’s blower at least once a year
  • Slide out the fan unit and clean each fan blade with a toothbrush and vacuum with an attachment
  • Look for oil ports on the motor, located near the motor shaft and apply 2-3 drops of non-detergent motor oil to each port.
