Yep, That's my opinion! If its wasn't why would it be stated in the flippin manual that it happens? I lived with mine for enough years to know that its does and will happen. Specially when you need it most and no back up means cold house when you get home. Igniter ohmed fine and feed gate was set to manual. It just happened with some of them. There are threads here about it and I believe Eric and I had a discussion in one of his Heatilator threads about it. He stated his did it on occasion. Its a Quad thing so, Hit the reset and get on with it!
