I have an Englander 25 pellet stove. I had a hopper fire. The hopper was half full and it smoldered for a while in the hopper before I caught it. I cleaned the entire stove out. I reloaded it and tried using it and heres what it does.....i turn it on and it will run for 5 to 30 seconds and it will shut off and show just an E on the display with no other letters or numbers. Sometimes it will run for 5 minutes or longer before it does this. No matter how long it tuns the augers dont work. I tried bypassing the vacuum switch and it didnt help. Chimney is clean and clear.....any ideas? TIA
