replaced my old motor with this one and its working great. Motor is quiet and easy to install. ***UPDATE*** 5/21/2016 Install it on June 4, 2015. It was working great during the summer. My attic gets very hot and the motor seems to be on constantly. Then this year, May 18, 2016, I went up to my attic and it was hot, over 95 degree. I set my thermostat to 90 and it wasn't working. Checked the current and it was getting electricity. Motor died. Call CSH Inc. who was the seller through Amazon. They were very nice and explained that I had to go through Amazon for the 1year warranty even though they were the seller since I bought it through Amazon Prime. CSH said to call them back if Amazon didn't help and they would help me. Amazon said they don't do warranty but would take it back with a 15% restocking fee. Amazon said I could call the manufacturer for the warranty. So I called Lomanco and they honored the warranty with no problem. They asked for the model #, manufacturing date which is in the motor but I didn't know it - I give them the date on the box and when I bought. They sent me a new replacement one. I didn't have to send back the defective one. I received it in 5 days, call Monday received it Saturday. Excellent customer service, excellent warranty. I hope the new motor lasts a lot longer than a year.

Works perfectly as a replacement so far. Found a YouTube video which was helpful as a guide - search for: Lomanco Attic Power Vent Fan Motor Replacement Maneuvering the fan/motor assembly out of the enclosure is much easier than the video shows - you might have to bend one of the three support arms (after removing the screws) to pull it out, but that's all that is necessary. It's much easier to disassemble and reassemble the fan blade to the new motor when it is completely out. The top of the shaft of my old fan motor was rusted so you may need to sand it a little and add some type of lubricant on the shaft (vaseline or WD-40) in order to be able to bang/shimmy the fan off the old one- once you have the old fan blade off, then it slides very easily onto the new replacement - put it at about the same offset from the top of the shaft as it was on the old fan. When reinstalling, after all looks connected, before powering up, rotate the fan freely by hand to make sure there is nothing hitting. If anything of the enclosure is hitting (such as a screen which is part of the outer enclosure), and the fan looks like its spinning pretty balanced, you may be able to bend the screen a little to stop the hitting. Once all looks good, then power it up and all should be well. My old motor was the exact same model with a manufacturer date in 2005 - I hope I can also get 10+ years out of this next one.

The old attic fan motor died and I initially bought a new motor from a large box store with the thought to reuse the blades I already had. BUT, the set screw was so tight into the motor rod that it was impossible to release it. My advice, don't bother. Buy the motor and new blades together. There is no instruction sheet enclosed so KEEP YOUR OLD ONE onhand so that you know which way the blades are facing). My old attic fan was attached using a belt bracket that went around the motor so the installation of this one was easy. You will need two people to install it, one to hold up the fan while the other one tights the screws. It's simple to rewire it, turned on the power and the fan went round and round. Hopefully it'll last at least 5 yrs. (the number of years my 1st one lasted. The blades seem sturdy enough even at $16. Replacement Fan Blade for Lomanco Power Vent Motor # 14393 For those who don't want to go onto a 2 story roof to replace an attic fan, this is the way to go. MOTOR AND BLADE COMBO

The Lomanco motor was practically speaking an exact fit. Some installation notes. Mine had a belly band connection. So the extra hardware was not necessary. I re-used the armor cable from the old fan. I loosened the three 3/8 in screws and bent back the arms just enough to angle out the old motor with fan blade attached. I took the whole assembly to my workbench sprayed down the set screw with PB blaster. I let it set for a little while tapped it with a hammer and used a long 5/32 Allen key to take it off. The shaft was shorter but I put the fan blade all the way at the end of the new shaft as far as it could go and there were no issues with clearance. I also added some extra 3-in-1 oil into the oil holes on both sides of the motor for extra longevity hopefully. I took my time and it was about an hour 's job. Watching the videos and having the right size Allen key and sockets in advance helped.

13 Aug 2015 Replace motor in center attic exhaust fan The center attic is the one above the upstairs master bedroom. It is accessible using the drop down ladder in the ceiling at the top of the stairs. 1) I ordered a replacement motor for the original, DM (Asia) Ltd. Model DOW-136-0-40-XIN-1*-D, from Amazon.com ($52.19). The replacement is a Lomanco Vents Model F0510B2944. It has the same outside diameter as the original (and therefore will fit exactly into the existing brackets of the exhaust fan). It is about 1/4" shorter in height and the fan blade mounting shaft extends from the motor by about 1/4" less than the original. These differences turn out not to matter. The Lomanco motor assumes a mounting scheme using brackets that attach to the three screws passing from top to bottom through the motor. The new motor came with three Universal Kit Bridges. My assembly mounted using a compression clamp around the motor. The nominal 5" diameter clamp is made up of three brackets attached to the fan housing. I did not use the Universal Kit Bridges. 2) To remove the existing motor: a) Disconnect the power at breaker 2-1. b) Open the control box mounted on the rafter near the exhaust fan and disconnect at the wire nuts the power wires to the motor. c) Remove the flexible metal conduit and strain relief at the control box. d) Using a 5/32" hex wrench, loosen the set screw holding the fan blade to the motor shaft. There is a flat on the shaft. [In this repair, I first removed the three screws (7/16" wrench and socket). Then I bent, messed with, etc., the motor with the fan blade still attached, removing it as a unit. It's better to leave the fan blade above the motor mounting bracket and drop the motor down by itself, by just loosening the three screws tightening the bracket around the motor. You have to mess a bit to get the flat at the set screw when assembling, but it's worth it. e) After loosening the set screw holding the fan blade to the motor shaft and removing it from the shaft, and the three screws holding the motor to the mounting bracket, drop the motor down and remove it. f) On my assembly, the motor electrical leads were protected by a flexible metal conduit that attaches to the motor and the control box. Remove the conduit by unscrewing it from the boss at the motor. Re-use it with the new motor. 3) To assemble the new motor to the fan blade and mounting bracket: a) Slide the new motor into the mounting bracket. Since the new motor and shaft were shorter in height than the original, the fan blade interferes with the mounting bracket by about 1/8" - 1/4". Slide the new motor up as far as it will go (limited by the boss for the flexible conduit). As best as possible, orient the motor so the shaft is normal to the plane of the motor (so it is not tilted in the bracket), to decrease the risk of interference of the fan blade with the bracket. Tighten the three screws to secure the motor in the bracket. b) Install the fan blade onto the motor shaft by feeling for the flat on the shaft to orient it with the set screw. Move the fan blade as high as practicable on the motor shaft to provide clearance between the blade and the motor mounting bracket. Tighten the set screw. Use a pliers or a lever (the box end of the 7/16" wrench) to tighten the set screw. Rotate the fan blade to test for clearance with the motor mounting bracket. There is about 1/8" clearance in this assembly. I did not have to bend the fan blades to provide clearance. c) Install the flexible metal conduit by sliding it over the two power leads and screwing it onto the boss at the motor. d) Install the flexible metal conduit to the control box by screwing the strain relief into the flexible conduit and attaching the strain relief to the control box. e) Attach the power (black) and neutral (white) wires to the respective wires using wire nuts (Step 2-b). 4) Test: a) Turn on power at breaker 2-1 b) Press the test switch to test for fan movement. c) Install the cover to the control box and set the control temperature to 90F (in this installation).

This perfectly fit my very old motor and fan. It looked identical in every way to the older fan, except cleaner and shinier. Tested it out and it works great.
