Recovery" and the flame is on the display, meaning it should be lighting soon or already lit. The thing is it never does, and I have
to turn off the furnace switch on the wall to reset the furnace. When
I do the damper motor closes and then I switch the power on then the
green light to the ignition control comes on and then after a few
seconds snaps 3-5 times then ignites. After that it cycles as usual.
The temperature is 5+ degrees lower than the night setting when this
happens meaning no heat has been generated.
This morning I awoke early to watch it go from night to morning
setting which would be the "Night in recovery" mode. The green light
came on the ignition control went on, then the igniters snapped 4-5
times, then whoosh the furnace ignited. Then after 5 seconds it shut
off, gas and flames but damper is still in open position. I then have
to turn the Power to the furnace off then off. Again the damper closes
and it ignites.
Could the Roll out switch need replacing? Is this a simple cleaning of
the various switches or a call to my friendly service man?
Thanks in advance.
