Hello All,
Hope somebody can shed some light on this problem for me....
Our furnace has electronic ignition, a damper and a Honeywell Programmable Thermostat. The furnace runs when the stat calls for heat, then shuts down. Here's the mystery. About a minute after the furnace stops, it fires up again and runs for approximately 10 secs, then shuts down again.
Any idea what could be causing this? I've tried 2 thermostats with no difference. Could the damper be causing this?
Thanks in advance for any suggestions.
