after furnace is lite it keeps on making a clicking sound like it is still trying to lite. after a short time the clicking stops. sometimes furnace will not turn back on. but if you turn electronic thermostate off and back on it will ignite click for short time then run fine for awhile
could someone shed some light?

Try cleaning or replacing the flame sensor. All check the pilot flame and make sure that you have the flame sensor engulfed by the blue mantle of the pilot flame.

Cozy.Support does not provide a diagnosis for users of this forum. We do, however, try to provide information that will help servicers arrive at their own diagnosis.
