Thermostat working, pilot lights. I tripped the breaker to 'off', Ten minutes later turned tstat to 80, turned on the breaker. Pilot lit instantly with good flame. During warm-up time, several loud clicks at two different times. TWO minutes later, burners fired nicely. Lowered tstat and unit shut down normally. Raised tstat.... identical results. Eight hours later, got the call for no heat. Repeated above, pilot lit and burners never fired...no clicks this time. Luckily it's warm today! Please help!

I tried your model number and as usual cannot get anything online at all. I wish their was a way to look up HVAC like appliances but their is no such thing that I know of. Until then I can only go by looking at what you have.

http://appliantology.org/topic/13876-rheem-furnace-clicks-somtimes-ignites-sometimes-not/

Thanks for the replies..... Another post here is at the above addy. The unit shown is identical to mine.

Gas valve is the 7100 DER and the igniter control is the 780-715U. I'm sorry, the unit is across town and the wiring diagram pasted in the inside of the furnace, so I don't have schematic. I'm mechanically

able and if I had trouble-shooting proceedures and testing target readings, I could isolate the problem and repair or replace the part...with your help of course. ;c). Thank you all for your help....I've been scouring the net but....there's SO much junk out there!!!

BTW, I got a call last night that the heat was working....then again this am saying it wasn't.

My guess is the gas valve. Tired solenoid, sticking valve.

Are you sure of model number, BTW? I can find GAD but not GDA.
