I recently bought a house with an Englander pellet stove that I believe is a 55-TRP22. When I first turned it on the auger would turn for a few minutes but not ignite, then shut off showing an E1 code. I assumed it was the igniter so I opened it up. There is power going to the igniter so maybe the igniter is bad? I also found this vacuum switch just sitting on the floor of the stove, wires connected but the hose was rotted and not connected to anything. I dug around for a replacement hose and hooked it up. It’s not the same kind of high temperature hose but that doesn’t seem to matter- I hooked it up and it does not make a difference. The auger turns, the pellets fill the hopper, SU appears on the digital read out, but no flame. I also tried moving the hose from the black to the grey part of the vacuum switch. This time when I fired it up, it would shut off after only 15 seconds or so, this time showing an E2 code when it shuts off and then an E1. I’ve done some reading online and in the owners guide online and I’m perplexed. I am sure it is a simple fix that I can do myself. Any thoughts from the experts here? Could it still be the igniter or should I be focusing on this vacuum switch?
