CTS MotorsNutone 62345000 Motor for LS100SE will also fit LS50SE and LS80SE J238-100-10074

Exact fit, easy to swap out and I am amazed at how quiet the exhaust fan is now. Cost was about the same as a completely new replacement however, the motor swap was less labor and much quicker.

If you are matching your original motor, this is a commercial rated motor. So don't order something chintzy to replace it. I believe these were about 1.5 sones if you bought one of these, because they had good fan blades. You do have to reuse the fan blade. It is removable. If I remember right oh, I believe I needed some needle nose pliers to squeeze a little clip together to slide it off of the motor shaft and then the fan blade came loose.

Purchased for installation in a LS100SE. The plastic support for the wiring to motor interferes with the fan support housing as it sticks out 3/16" on both sides more than the OEM motor which does not have those extra plastic sections.After trimming the plastic corners and re-routing the motor wiring, I was able to barley make it fit without the wire rubbing onto the fan impeller. However the motor is running approximately half the speed of the original motor.

This was the correct replacement item and easy to install, if you know how. I got part way in and it was a mess, luckily found a YouTube video that showed how. Essentially you remove the entire side of the fan assembly, then remove the old fan motor from the underside. Then there is a trick to pop the shafts out of the fan blade assembly.Next install new motor and put on the flan blades, then be sure the flapper door is in the right hole and put assembly back together and remount. Good luck..remember to watch the YouTube video..just search product name and add the word install in YouTube search. Product works fine.

perfect fit for my old bathroom ventilation assembly

This is the second replacement motor I've purchased. Installation was easy, but power cord is shorter than original, but still enough slack to install. Last one made it about 3 years. This one works, but the fan speed is notably slower and therefore lower airflow. Windows steam up easily which didn't happen with original and first replacement unit.

Arrived on time and works in my 20 year old Nutone LS100se fan. The only thing that was strange, was initially it made a strange sound and the shaft didn't spin well. After some WD40 and a closer look, the screws holding together the transformer windings/case were loose. After tightening these up, the motor worked fine. Hopefully another 20 years of operation ahead.

As other have reported, I can confirm that this replacement unit is not of the same quality as the original. This is often the case with cheap, Chinese replacement motors for all sorts of things. Well, this is no exception. It fits, it runs, and moves a small amount of air but it lacks power and doesn’t move anywhere near the CFM rating for the unit as a whole. My guess is that the manufacturer skimped on the expensive part this replacement motor; the copper windings (if they are even made of copper). I suggest trying to source a factory original replacement. I will be doing so. Two stars because it is compatible and operates, technically.
