Try these helpful tips first:

  • Check the batteries in your thermostat,  Newer digital thermostats use batteries to work but not all. (Note: leave batteries out for 30 minutes then reinstall them into thermostat.)
  • Is the power to the furnace on?  Sounds silly but power switches on the side of furnace can sometimes be turned off accidentally 
  • Are the furnace doors all the way on?   On newer furnaces if the doors are not all the way on it will not allow the furnace to operate 
  • If your furnace has an air filter,  is it clean?  Dirty filters can cause a variety of problems and lead to furnace failure.  You should change your filter, at minimum,  twice a year.
