Furnace Repair: The Blower is Running Constantly

Blower Does Not Turn Off - Always Running

Sometimes the blower on the furnace will continue to run even when it's not circulating warm air. If you notice that cooler air is coming out of your ducts, you may not need to repair the furnace, but just the blower.

Possible Causes

  1. Thermostat set to fan continuous
  2. Faulty fan limit control switch on furnace (if thermostat has no fan setting)

Possible Repairs

  1. Change thermostat fan setting
  2. Reset or replace furnace fan limit control switch
