Questions & Answers

Replacement fan blades?

I just installed this motor, and it is vibrating badly. Im guessing due to a bent fan blade that is throwing it out of balance. Do anyone know the part number or what fan blade will mount to this. The only blade i can find is by a different company. Thanks.

Does this Motor Fit the Leslie Locke PR-4 power roof vent?
Asked by: Jkane
I guess so, I ordered it and my handyman put it up. So I guess it must’ve fit fine because he Didn’t have any problems replacing it after removing the old one. It’s been working just fine through all this hot weather last year and this year.

Replacement Power Vent Motor for PR3 and PG3 Series Vents is rated 4.4 out of 5 by 255.

Found "PC163" user's review/install comments to be helpful. It would be easier to remove the fan blades before uninstalling the motor if you can. But my blades were frozen to shaft even after many shots of wd-40 and loosening set screw. Had to pull the whole thing down and use a persuader (hammer) to help jar the blade loose. Once I got the blades off, I inserted the blades back up into the roof vent (the motor bracekts will hold the blades up there, and then installed the motor. I also used a piece of 12 gauge wire that I hooked around opposing brackets and underneath the motor to hold it in place while I re-tightened the housing bolts. This still took 3 or 4 tries to get right. Agree with everyone that the floating spacer is a PITA. Also used lots of electrical tape to hold the spacer still while sliding into the belly belt brackets. A 1/4 passthru ratchet worked well for the nuts. Will see how it holds up, the original OEM motor lasted 21 years.

Rated 5 out of 5 by from great product replacement, but one instruction not mentioned This motor is substantially "taller" than ordinary replacement motors. Although it fit nicely into my old vent housing. This pro series motor is very "beefy". If the quality is as good as it appears, this motor should last a lot longer than other OEM replacements. The motor comes with a "shim ring" that is required to be installed in most fan motor brackets. This caused me some delay in trying to figure out how to install the shim ring along with the motor. I finally used electrical tape strips to attach the shim ring into my old fan bracket. This holds the shim ring in place. Then it is relatively simple to slide the motor into the shim ring and hold it in place while tightening the bracket adjustment bolts. - This motor runs much more quiet than my old motor. Very pleased so far. I think it is well worth the extra cost for a pro series motor. PS: I should mention that I installed the motor from the roof, since I did not need to replace the thermostat..

Had to install (06/09/18) the motor from the attic while standing on trusses since there was no floor. Access was through a space opening in a closet. The replacement motor came with a spacer clip for use with the PR3 motor (I assume that some motors came loose in their mountings) which I used. This made the installation slightly more difficult to hold the motor/spacer while trying to fit it above my head into the clamps and tighten the clamp bolts. This also made it difficult to hold the blades out of the way so they are not damaged, while installing the motor (not enough hands). Once the motor was in place, re-installing the blades was not a problem, except to tighten the set screw holding it in place without damaging the blades. Once that was done and checked that the blades and motor were turning properly without hitting anything by hand, all that was left was connecting the electrical, which was a no brainer. Turned the power on and adjusted the thermostat and everything was working fine. Will let you know what the longevity of the motor is as time goes on.

I cannot hear it when it comes on as I did with the last one. It is easy to install, but wish that you did not need to bother with the loose extra spacer clip to attach the motor. If it had a permit spacer clip it would have made it easier to install, especially when it is 120 degrees in the attic.All in all a great motor and hopefully it will last 15 years as the one it replaced. I have the temperature set at 95, so it runs all the time in the summer.

Their jury rig to fix this error is to throw in a flimsy loose wrong-sized aluminum strip to make it tighter in your bracket. That might be fine if the strip fit in the gap of the motor housing, but it doesn't because is slightly too wide. So, when you fully loosen the bracket and try to slide the motor into the bracket the strip will slide down out of place so that the bracket doesn't get a full bite.

Installation was done from inside myattic, unbolting the old motor required a deep socket and a regular socket (two socket ratchets). I taped and marked the old motor wiring before removing the old motor and then connected thenew motor wiring based on the tape I used to mark the wiring connections. I also had a largebox fan circulating the air in attic during the installation.

The product fit nicely, did not need the spacer ring although based on my model (PR3-VSR300) said I would. Was much easier to install without the ring and it is holding firm. On the downside the original motor was variable speed, but the replacement only comes in single speed but it is cooling my garage down again which is nice.

Motor is physically a little longer,but presented no installation problems.The aluminum spacer ring around the motor center is a pain to keep in position while you tighten band clamp bolts.This motor draws less amps than the older one.All in all I was well pleased.Got it in 2 days with free shipping.
