I have a Drolet ECO-65 pellet stove and there appears to be a problem with the control panel. The LED display is not working. The only LED visible at all is the 1 red dot that signifies that the temp is at lowest setting. If i try to turn unit temperature up there is nothing that happens when i push the "up" button. When i push the "down" button it beeps when pushed. I want to order the part to replace but I'm not certain if i need to get the Membrane switch on cover which is a $40 part or if i have to order the housing for electronic control board membrane which is a $295.00 part. Can anyone give me any insight on this? The stove does work but it runs at lowest temp .
