    Heat pump runs, but Furnace won't start when it's cold

    My heat pump runs even when it's under 22 degrees. My furnace won't start when it's supposed to. Last night it was about 5 degrees outside and my themostat was set to 68 degrees and the temperature in the house got down to 55 degrees. I can run the furnace using the "EM Heat" setting on my thermostat.

    We got lots of snow which drifted all around the heat pump. I cleared most of that away this morning. Could that have caused the problem? Any other advice on what to do?

    Thanks, Jack

    What thermostat is controlling it?

    How many times must one fix something before it is fixed?

    It is a Honeywell thermostat. I don't know the exact model number, but when I search the web, it looks like the TB8220U.

    It has been functioning correctly (I think) for almost 4 years. This problem just started last night.

    Then you'll need a tech to check to see what is wrong.
