This may not be relevant.. but live on long island.. just coming out of hurricane sandy... no power... had generator wired into panel so heat was working fine.. until power was restored... flipped disconnect switch now back on utility power... is it possible from running heater on generator for 9 days at probably lesser power than normal... that now being on utility power that something could have burnt out.. I have power to the unit I checked with a basic hot volt meter that just light up red for hot from the emergency shut off switch on the side of the unit... is it possible to jump the transformer to see if possible the low voltage trans. Burnt out from the normal power levels... or any other type of process I can eliminate.. this is an automatic pilot system like you have on your gas stove so I'm not getting that clicking of the ignitor... thanks in advance for any trouble shooting tips its cold and snowing on top of everything that happened with the hurricane
