Topic tags/keywords: laguna cyclone motor centrifugal switch

If you have a Laguna 2hp dust collector, and the motor starts making a ticking/squeaking noise when the impeller spins down, your motor may have a bad centrifugal switch.

Background: I bought a Laguna Mobile Cyclone 2HP (Model Number: MDC0560-0145) in October of 2015. It performed just fine for almost three years. Then, the motor started making a ticking / squeaking noise when I powered it off and the impeller was spinning down. Eventually, it wouldn’t start on it’s own … it would draw so much current on startup it would kick the overload protection off. If I could reset the breaker while the impeller was spinning and hit the ‘On’ button, it would start up and run.

When I called Laguna’s tech support, the tech advised that the bearings had likely gone out of the motor. Since my machine was out of out of warranty, a replacement motor would cost me something north of $300, but they were on back-order for several weeks.

I decided to shop around for a quicker solution, and found a guy with a new-in-the-box motor that he was willing to sell me at a reasonable price. He had the NIB motor because his machine wouldn’t run, but it was under warranty and Laguna shipped him a replacement. In the meantime, he determined (on his own) that one of the two capacitors was bad. He replaced the capacitor and never even opened the box containing the new motor.

I installed the replacement motor, and it ran like a Swiss watch … for about 6 months! Then, it started making the same noise the original motor did.

I took the original motor to a local rebuilder, who went through it and determined the problem was not the bearings, but rather a worn centrifugal starter switch. The cost to repair it: $90.

I should have gone to the local motor shop in the first place!

I haven’t installed the repaired motor yet … maybe I’ll just wait until the replacement motor craps out, then switch them out and have the replacement repaired.

I wonder if anybody else has had problems with the motor on their Laguna cyclone?

The “warranty” an age-old question. They bet that it will last – we are being reassured they’ll take care of it. This is no different than buying; life insurance, car or a Home Depot extended protection plan…
Yes, when it happens to us, as stated above-
From past experiences- negotiate a remedy, try to “fix” it yourself and the most painful- get rid of it. I say this for I’m sure many LJocks have had to deal with similar issues.

OK, at the very start, I got the impression that it all worked FINE without any noise, etc. once it got started.
The motor turns the impeller, right? When you turn it off, the motor is turned off & eventually stops. The impeller continues to spin-down, making noises.

Tech blames it on the Motor?!

Sounds like the Motor is working just fine…
It’s bearings in the impeller that sounds like have gone… I would check all of the bearing in the impeller, one on each end… turn it by hand feeling each bearing looking for grinding operation (NOT SMOOTH)... Then investigate what bearings are required… and look on McMaster Carr for a replacement(s).

I did NOT read ALL of the post… The very first paragraph didn’t sound right to me.

Hope this helps.

Good Luck!

The impeller is mounted directly to the motor shaft … no bearings on the impeller.

Sounds like Laguna not only doesn’t care, but they are still producing the same problem and the “tech” conveniently diagnosed (incorrectly) a problem that maximizes profits for the very company unwilling to stand behind their product.

Thanks for posting, I bought a 2hp in October 2018.
I will try to remember this for future reference.

As for a company not caring- not enough evidence to say that I agree with you. But when a product manufacturer gets a class action lawsuit for a particular problem- then there is a reason to suspect bad product or cover-up. For example, Boeing 737 Super Max, substantiated by facts- not a one post review on LJocks.

I’m already seeing 100% more than you’re stating in this single thread.

Aren’t most impellers driven by a belt?

Sounds like this design is there just to Fail… (?)

Search me … I have never seen a dust collector that didn’t have the impeller attached directly to the motor shaft. Several manufacturers (Laguna, Jet, Powermatic, Baileigh, Oneida, etc.) use this same or similar design.

OK, it seems like our heating system is using a belt for driving the squirrel cage blower… Sounds like there might be a Balancing problem…
