What can possibly be wrong with my furnace?
What can possibly be wrong with my furnace? The temperature keeps dropping even though i set the temperature at 68F, and the furnace won't run to raise the temperature back to 68F. So, why? I am sure it is a gas furnace, and i don't think i need to reset it because it was running well just last night. This has occured several times, and i know the furnace is not broken but the temperature automatically drops even though i set to hold the temperature at 68F.

wrong section but first off check your filter a dirty filter can make the pressure relief switch shut the furnace off and it will never stay on for a full cycle therefor never really getting the heat up to temp. If it's not the filter you might check to make sure the furnace doors are on correctly there a switch that is usually on the door that if its not depressed won't allow the furnace to kick on. Something blocking a flue (vent) can cause the furnace to kick off (again at the pressure relief switch) Other than those simple things that you can check yourself you should call a HVAC guy.

I would check to make sure its gas for sure. Im not familiar with gas furnaces and dont know if they have a filter in them, but they may. It could be a filter issue. I like to keep up on furnaces and nfl knowledge
