My heater had also quit working, a combination of a corroded switch, rat chewed wiring, and a blower motor that had lost it's bearing. I couldn't find a replacement assembly anywhere for an E series machine. However, I found a chinese looking blower motor assembly that looked the same and had the same dimensions. It only costed me 110$ for the whole unit. The housing is very cheap plastic and I didn't like it, so I took my old one apart, took the motor and fan wheels outta the new one, and made one good unit from both of them. All 3 speeds work and it blows strong. The motor and wheels can be bought for about 80$ without the cheap housing, included is a picture of what I believe to be the motor part number
