So it starts up perfectly it lights it reaches temp and the thermostat kicks in to turn it off but the little box just buzzes and never actually turns off so it effectively just stays on while buzzing once it reaches temp and goes above temp. I can test the thermostat just by going back and forth past the current temperature if I go above the current temperature it's quiet and just stays on I go below the current temperature the buzzing kicks in like it's trying to turn off the valve but nothing happens it just stays lit. It sounds like a little magnetic relay is just buzzing in there for what I can tell it's probably like part of the electronic fuel valve I'm guessing. Problem is I have to fix it I can't order a part it's literally impossible at our location to replace a part so I have to fix what's here. Any ideas?
It sounds like the electronic fuel valve might be malfunctioning and not shutting off properly, which could be causing the buzzing sound you're hearing. Here are a few things you can try to fix the issue:
