Installed an old enviro ef3 dial a fire insert this past fall(non circuitboard). Has worked great until tonight. Pulled it out for some cleaning/lube, and when I slid it back in it won't feed pellets. When you push the start button everything works (green light comes on for a second, fans/igniter work till they time out.) but the pellet feed appears dead. No matter where you put the dial a fire knob nothing happens.... not blinking light, not auger. The knob felt a little funny when I turned it too. Anyone have this issue? How do I test the dial control? Could you use a different rheostat to get by with if till a factory one comes if that was it? Thanks
