Customer Questions & Answers

Will this fit the old PR2 model with three leg mounting from the bottom of the motor?

I have the old PR2 model attic fan with three-leg mounting from the bottom of the motor. The new mounting is the four-leg bracket. Will this motor be compatible with the old mounting scheme?
Asked by: Wei
Master flow say "No" to fit this replacement motor to the old three-leg PR2/HI22. So, is there one on the market can be used for the old PR2 model?

is this motor thermal protected

Asked by: josh
Blackfrog is incorrect. The "little black box" is the start/run capacitor, not a thermal protect. https://en.wikipedia.org/wiki/Motor_capacitor

Rated 4 out of 5 by from These motors require maintenance every 2-3 years. Have used this roof vent system for 30 years, replaced a couple of times when the plastic dome, not the metal one deteriorated in TX sun. The motor has only bronze sleeve bearings that require periodic cleaning and lubrication. Have looked for, but never found a ball bearing motor for this application. To cut down on dust entering the shaft end of the motor, cut a 2 inch diameter leather or rubber circle, punch a 7/16 hole in the center and slip over the shaft between the motor and fan. One can get 15-20 years out of a motor with some regular care and lubrication. The new motor is a capacitor run motor drawing 1.6 amp instead of 3-4 amps. A motor with sealed ball bearing and thrust bearing would solve the problem.

Rated 4 out of 5 by from The Big Picture In looking over the other comments, I want to stress my observations are merely my own opinion. As to the motor replacement frequency, I can only say my previous replacement, the motor lasted four years. I cannot say if this is good or bad. I suppose it depends upon its operating environment. In very hot climates, the motor is subjected to hours of continuous duty in adverse temperatures. I did an autopsy on the failed unit and indeed the culprit is the bearings. It appears the grease does not stay in contact with the actual bearings, but maybe slung out during operation. As someone pointed out, there is no thermostat in the box. I don’t think there is supposed to be. They are usually accessories separate from the motor (I used the one I already had). I cannot address the need for instruction sheets, but replacement, for me was quick and straight forward. This is what I did. 1) Pull the circuit breaker (verify cold at the unit with a volt meter) 2) Remove wire nuts and release wires connecting old motor to house electrical system (make a note of where each wire goes so you can replicate their position during reinstallation) 3) Take 1/8” Allen Wrench, loosen nut holding the fan blade to the motor shaft and slide fan blade off (there is no need to remove fan from housing when replacing motor) 4) Carefully loosen two of the three collar nuts/bolts (I used 7/16” wrenches) holding fan centered in the housing. You need only loose two enough you can slide the motor out of the housing – don’t drop it). 5) Using the new motor, you reverse the process. 6) Slide the new motor into place in the support collar, but only snug the bolts – don’t tighten – in case you need to adjust its position/orientation. 7) Slide the fan blade back onto the shaft and tighten the Allen nut (note: the nut faces the flat portion of the shaft). 8) Spin the blade by hand, ensuring it rotates freely, does not touch any portion of the housing and is centered in the collar and while ensuring the motor is evenly distributed – not cockeyed- in the collar. The fan/motor insertion should position the fan at a distance to ensure the fan pulls hot air and ejects it in a balanced quantity. Now tighten the supporting bolts 9) Properly reconnect and secure the electrical connections. Restore electrical power, adjust thermostat, 10) Bask in the glory of a job well done.

Rated 1 out of 5 by from Not compatible with existing Exhaust unit bought this to replace the one i installed about a year ago. it doesn't fit the exhaust unit that is in the roof. the mounting bolts are only three whereas the unit needs four bolts. thought i could still use this by buying three new mounting bolts but unfortunately the holes in the motor housing are not drilled thru so i had to scrap that idea. this resulted in me having to buy a whole new rooftop fan and call the roofer to have it installed. i rate the quality as fair as the one i put in about a year ago had its bearings fail and it stopped running just when i needed it most. poor value. wouldn't recommend it.
