Should I change the Boiler Control (Mod# 1013-200)?
My Weil-McClain HE II did not start up on its own last night or this morning. I had to turn off the service switch off and then on to get it to work. Had a service guy here for two hours, and the boiler acted fine. I notice that there is a loud repetitive clicking everyday. I was told that the sound is the gas valve opening and/or closing, and that the Circuit Board is what controls the gas valve. It should not be opening and closing that rapid and often correct? Of course it did not do this when the Service Tech was here, but it does so many times every day.
