Majestic DV 260 Honeywell comfot control RF valve
Did a clean and service on a Majestic with the RF comfort control valve and was pretty unprepared. I have never seen a valve with 2 thermopiles connected that way and to see the printed circuit board directly on the valve and the big motor top cap protruding out looked weird. The call was that the pilot would stay lit and burners would not come on.
Just wondered if you guys come across these valves a bit and what should I be looking for in faults, I know the valve troubleshoots itself but what components seem to failure prematurely on this system.
Thanks for the help and have a nice one.
