Hi i have a problem with my Enviro Ef3 pellet stove. The auger and auger light will only work when the dial-a-fire is on high. On any other setting the light wont come on and the auger does nothing. I checked and the vacuum hose was clear and if i bypass the vacuum switch it changes nothing. The exhaust motor is working and clean. I was wondering if it might be the Dial-a-fire controller or the auger timer control. Does anyone know how to test the Dial-a-fire controller? Thank you in advance. Mike
