Heng's (90037-C1 12V Vent Motor

Easy to install and a much cheaper solution than an entirely new fan. Last one lasted 8 years, here’s hoping this one does also.

May be a little early to tell, but item is working as expected. RPM is at least as good as the one replaced. Delivery was very quick. Was an exact replacement for the M3 Hengs in our vent a hood. Did not have to make any modifications. Only drawback of any kind was that it did not have a quick clip on the wire, so had to cut the old one off the old motor and splice it in.

Finally installed this motor a Year after purchasing. The old one suddenly started working again right after I got the new one. So I left it until it finally died this year. Installation was fairly easy and it works just fine so far. Just as quiet as the old one. Would be helpful if they included mounting screws with it also as I nearly destroyed the head of one trying to get it loose. Gave it 4 stars for that reason and since it came with a different name on the package instead of Hengs as advertised. Will wait to see how long it lasts.

This fan works to replace the bathroom fan in my 2016 keystone sprinter. I had to drill three new holes to mount it right as this motor was a little bigger than the old one. Also I had to switch polarity to make the fan turn the correct direction. I drilled a slightly bigger shaft hole in the fan but that seems to work fine I had to drill three new holes to mount it right as this motor was a little bigger than the old one.

Step 0: Ensure you have power going to fan motor to ensure motor is bad. Then add this to cart and click BUY.Step 1: Phillips #2 screwdriver- Remove vent trim carefullyStep 2: Phillips #2 - remove screen. Unscrew crank and remove crank. Unscrew plastic round nut that holds push switch to screen. Remove screen carefully and see how the wires were tucked away for when you install.Step 3: Phillips #1 - remove fan blades carefully by pulling down on the fan using the thick part closest to the center of the blades. It pulls off. Some have clips, but my 2000 RV PaceArrow didn't.Then remove the 2 small screws that hold motor on.Step 4: I touched wires to new motor to ensure it worked. It did so I put it in place with the 2 tiny screws.Step 5: cut existing wires to proper length. The old motor is hanging, remove old wires from bracket hole and feed new wires through. Remove wire insulation for the white wires and use butt connector and crimp them down. I used wire nuts, but crimping is better. Then do the same with the black wires. Basically if your confused just do one wire at a time.Step 6: Move wires to the side and zip tie if needed. Push fan blade back on. If not enough confident friction to keep blade on, put a piece of potato chip bag over the hole to take up some room and push it on.Step 7: Push wires aside, push button and test. Now you're happy! Hide the wires and put it back together.NOTE: Do not overtighten trim screws or you'll break the plastic.

Easy enough to install: removed old motor, threaded wires through vent, crimped on correct wire connectors, screwed in place, snapped fan onto new motor.This was an exact fit for my old fan motor and works perfectly once installed.I am very happy with my purchase and would buy this product again.

It works and was a good price.

The description says it's compatible with Ventline...well, maybe some Ventline products, but not the roof vent in my RV. It almost fits but the collar on the shaft was slightly bigger than on the old motor and the holes for the little bolts that hold it to the bracket were spaced farther apart and were for a slightly larger diameter bolt -- no bolts were included with the fan. I drilled a bigger hole for the collar to fit into on the bracket, new holes, and got some tiny bolts from a hobby shop. The shaft is slightly longer than the old one, too, but it didn't cause a problem in my particular installation. That said, it's more powerful than the motor it replaced and pulls a bit more air. Even knowing about the incompatibilities, I'd probably buy it again -- the OEM imotor is three times as expensive -- but anyone purchasing it to replace a Ventline roof vent should be prepared to do a little modification.
