I purchased a brand new Englander. 25-CB120 pellet stove directly from Englander installed last night ran for few hours…. And it stopped working in middle of night. Got up this morning cleaned burn pot and will not ignite at all!! I emailed & left vmail Englander 1st thing this morning….. and no one has responded! Any ideas why it won’t re-light? And, I cannot get it in diagnostic mode by pressing up & down button simultaneously.
