My heating is not working possible Low water cut off device
Hi, im a novice in heating but i have a williamson -thermoflo gwa and for some reason when i call for heat nothing fires up. i can see the flame on in the burner but nothing will turn on. the lights on my low water gaurd dog rb-24 are not on. usually its green or red but no lights. could it be that i have to replace the gaurd dog because it shorted?
