Review on Heng's 12-Volt Power Vent Motor Replacement, 90037-C1 Replacement Vent Motor by Dre Fowler

The description says it is compatible with Ventline. Well, maybe with some Ventline products, but not with the vent on the roof of my motorhome. It almost fits, but the collar on the shaft was slightly larger than on the old motor and the holes for the small screws holding it to the bracket were spaced further apart and meant for a slightly larger diameter screw - the screws were not included . Fan. I drilled a larger hole to fit the ring in the bracket, new holes and bought some tiny screws from a hobby store. The shaft is also a bit longer than the old one, but that didn't cause any problems in my particular setup. However, it is more powerful than the replaced engine and draws a little more air. Even knowing the incompatibility, I'd probably buy it again - the OEM iMotor is three times the price - but anyone buying it to replace a Ventline roof vent should be prepared for a minor modification.
