Question about Heating & Cooling
I have a Williams wall heater, the pilot light works fine, but the heater will not turn on. I thought the thermostat stopped functioning, but I've eliminated that. Silly as it sounds: tapping the gas valve a few times makes the furnace start up and do it's job, however, when it cools down again, past the indicated desired temp on the thermostat, I have to tap it again to start it again. Is there an easy/cheap solution to fix this? Can I clean it out or something along those lines?

It sounds like the gas valve has some debris in it that is causing internal relay from opening without some help. I would check and clean electrical connections on gas valve and make sure you are getting at least 24 volts to gas valve when thermostat iscalling for heat. I would also actuate gas valve several times in a row to see if it frees up any. If that doesn't help you probably need to replace gas valve. I think you will need a new valve but it's worth a try. Good luck. Thank you.
