The furnace will fire if I turn the switch off on the side of the furnace for even 10 seconds and then turn it back on then the gas valve opens and the furnace gets. hot. But after one cycle the gas valve does not re open for another cycle unless I cut and then restore the power to the unit.
Fan runs all the time
induction motor runs all the time.
pilot is lit
Anyone got any ideas?
