With the original thermostat (non-digital, year 2009) my Atwood 8012 furnace would not shut off - a recent development. The gas would cut out but before the fan finished it's cool down cycle the furnace would reignite and continue in that off/on cycle until I manually turned off the thermostat. Or I could turn it way down and it would go off. This led to a couple of very uncomfortable nights at a trailhead camp, but fortunately it caused me to be awake at 3:00 am to hear the bear circling my camp. I think it was a little upset about my llamas. Anyway...
Back home a local technician did a bench test of the furnace control board and said it was good, my problem was the thermostat. That was good news; just the incentive I needed to upgrade to the digital Honeywell TH1100 heat only. So I did and it changed the way my furnace operates, but not so much for the better.
Now the furnace shuts off when it eventually gets to the set point, but on it's way to reaching set point the flame kicks in and out about every 12-15 seconds. The furnace grill never gets hot to the touch, just warm. I've only used the furnace a couple of times with the new thermostat and both times were at home, with the top down, in mild weather. Camper temp. was about 45 degrees and I set the thermostat to 60. After initially burning for about a minute the furnace began to short cycle and I doubt it would make the set point in colder weather with the top up.
Anybody else have issues like this?
Thanks
