Question about Williams 3003622 Ceramic Wall Mounted Panel Heater
It sounds to me like you have some small dirt or rust particles inside the gas valve that are hindering the valve from fully opening. Before I spent the money for a new gas valve I would make sure that the burners were clean and also clean pilot orifice. Replace thermocouple if it appears to be burned or deformed. You can turn thermostat up a little bit at a time and try tappimg on valve body to see if you can get it to free up. Unfourtunatly there are no repairable parts insid the gas valve so if it comes to that you will need to replace the valve. Hope this helps you and thanks.
