Hello:

Does anyone have any service information on this product? Have
problems in the console which is labled MW6LD1A SIX WINDOW CONSOLE
Z86C90 Version AW REV> A. Seems that Proform Fitness Products, the
supplier was sold to Icon in about 1996 and Icon has no information on
the product. Belt runs at max speed upon plug in to AC and the console
will not control.

Thanks,

Bruce

It's probably not the console but the motor control board. Usually these
have some SCRs or MOSFETs to control the motor, if they short, the motor
will run full speed.

relay) to prevent this.

I shoud have given more info in my original post.

Originally the console did nothing except all the indicators were
flashing. Replacing the motor control module has the motor running
upon the application of AC but the console has no control. Unplugging
the cable at the console and the motor stops. The safety switch on the
console is OK.

Unable to get any info from Lesco to date.

Thanks,

Bruce

In the absence of information, I'd be scoping the cable at the console
and looking for tacho feedback pulses from the motor and PWM pulses
from the controller.

Wouldn't hurt to start by checking the power supply to the console,
dried out electrolytic capacitors can cause all sorts of weird stuff.- Hide quoted text -

Thanks James, Thanks Franc:

There was nothing wrong with the console. I let myself be side tracked
by the Service Tech that wanted to replace it but admitting that it
may not be the problem. Seems that the console does not function too
well without B+. The 4700 mfd cap in the power supply lost quite a few
mfds as it operates fine with a 470 mfd unit which was all I had. Have
ordered the 4700 plus some others to replace all the lytics.
