Rated 3.5 out of 5 by 56 reviewers.
Rated 5 out of 5 by FAN-tastic I purchased the PR2-HI22 in 4/8/2001 and installed a lighted inline switch in the closet to turn the unit off in the winter. The light install is attached to the dead side of the wire/switch, so when switched on there is a light indicator. I have not replaced the motor but purchased this replacement motor, just in case it is needed. I feel most who have had issues set the trip level too low which results in higher fan operation. Although, if you follow the instructions it recommends 105° F, I set the thermostat to 118° F. I also did my best to make sure the thermostat gets plenty of air flow when the motor is operating. Hope this information will assist those who have had issues. June 4, 2013
Rated 2 out of 5 by Consider it a consumable Razor blades are designed to wear out after a certain number of uses and so too are these motors. I recently purchased a new residence and the seller had two of these motors on hand to replace the two failed ones up in the attic. I placed a thermo probe in the attic prior to replacement - temp reached a high of 141 deg F. After replacement we are down to 102 deg F. As others have said, you need 2x 7/16 wrenches and an allen wrench (mine required 5/32 - odd). The bolt/nut removal for the housing is easiest when you have one socket drive and one closed end wrench. The fan is fairly loud when running but I can't hear it once my attic access door is closed.

Rated 1 out of 5 by Attic Fan Replacement Motor This motor replaced a previous replacement that burned out. I didnt realize when i installed the attic fan that i would need to replace the motor every 3-5 years. I guess they dont make things like they used to!!! August 20, 2014
Rated 1 out of 5 by lasts 1 year then quits had to replace these motors every year like clock work every spring i go in attic and they are locked up my last motors before this brand lasted on average 12 years i give up gonna have to find another source April 21, 2014
Rated 4 out of 5 by 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. July 1, 2012
