Retro fit into old B/M Model 41 type K
I have 10 of these units in my house that were made in approx. 1972 and the fans on some have worn out. Some of the units are hard to get to without ripping out walls and kitchen counters so it is not too easy to get a new unit in place. I tried to get fan replacements from B/M two years ago and they said they had nothing as the old motor/fan contractor they used went out of business (Tron). So now they have this new unit #K-42. This new unit has a fan/motor replacement available and I thought I would try this. This assembly fits into the old unit perfectly. These new K-42 fan/motor replacements have wiring for a 3 position switch which does not exist on the old units. So you have 2 hot leads--you only need one of them. The red lead makes the fan run slow, the black lead makes the fan run fast-so take your pick and tape the unused one back out of the way. Connect the grounds and you are all set.

Major vibration.
I'm afraid I'm quite dissapointed in the blowers. One of them I had to replace an old blower fan with the new motor for it was so off center it made a terrible vibration in the whole house when on. Another one is doing the same thing but I have not had a chance to replace it yet. Not sure what to do now......

Works fine
Works fine and fits perfectly but they don't work forever and seem to cost more than they are worth.

Just what I needed
The fan on my 20 year old K42 finally quit. A direct replacement and as usual Supply House had it in stock at a better price than anyone else!

Fits K41 with modifications
There are no K41 replacement fan assy's so I ordered this K42. The wires are different and the fan shroud is more open than the K41. The metal electric box on the K41 is small and doesn't fit completely over the larger k42 motor connectors. Some aluminum tape fixed that.
I tried the k42 shroud but it was noisier than the noisy K41 so I took it all apart and used the K41 shroud with new fan and rubber bushing. Now it's nice and quiet again.
Turns out that the rubber bearing holder in the old one had dried and split causing the k41 to vibrate. All it really needed was a rubber bushing that no one makes available. You buy the whole assenbly.

Fast, accurate order entry. Quick delivery.
I thought they might give preference to large, professional customers. I was absolutely amazed with their service, price, and delivery for my DIY order.

I would buy this Motor Fan assembly again
With a little manipulation, I have it working on my Beacon Morris K41A kickspace under counter heater.

Works perfect!
Needed a replacement for the unit my house that was from the 80's. Easy installation and great fit. I don't know what some of these other review are talking about with noise. This thing is whisper quiet. Will definitely buy again if it ever needs replacing.

This blower works fine and fits perfectly but it costs more than it's worth. I hope it lasts the rest of my life.

Q: can i use either the k42 or k84 replacement notor in my home for my heater if i cant find which model i have
Asked by plumber56 16 years ago

Verified Reply- PexSupply StaffNo, you cannot. The motors are sized for specific models and must be used with the models for which they are intended.

Q: I looked at one of these heater that was not functioning. After coaxing the motor for a while I got it to spin but I think the motor assembly needs to be replaced. I wrote down the part number as I thought it was printed and it said K82. Is this the same motor unit for that heater? THe picture shown here looks identical.
Asked by Mark 16 years ago

Verified Reply- PexSupply StaffNo. The K82 is no longer manufactured and no parts are available.

Q: I would like to install this fan on my wood stove (with custom built shrouds). Is it a 110 volt unit that can be operated stand alone?
