|
|
| I have a 20 year old Weil-McLain natural gas hot water boiler (model CGM-6) which every once in a while will not fire up. The thermostat is calling for heat and the circulator is going but the tank is at room temperature. The only way I can get it to fire up is to turn the electrical power off and then on again. I've had this problem for some time now but it seems to be getting worse. I'm suspecting a faulty temperature limit control but I don't know enough about it. Can someone help? Thank you very much. |
