Recently I've been having trouble with my furnace not coming on when the thermostat is calling for heat. It will work fine all day and then upon waking up the temp will be at 58 when it should be 66. If I turn the heat off and then back on it will fire up and heat fine. My first guess was to buy a new thermostat, but that didn't fix the problem.
Any heating and cooling experts out there who can advise me on what might be the problem. My second thought is that there is a sticky relay or perhaps a bad ignitor (it's a high efficiency pilotless furnace). I'm thinking of opening up the unit and tapping on any relay looking thing I can find to see if that will bring it to life. I'm quite handy mechanically, so would like to avoid a furnace repairman if possible. But, I definitely have to fix it reliably before my next TS trip.
