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.

I agree, although I'm wondering why there is no safety device (eg a 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,

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.

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.

Hey cool, always nice to hit the nail on the head like that.

I'm STILL seeing fallout from the faulty electrolyte fiasco years ago, for a while it was really bad with equipment of all sorts dropping like flies. Prior to that it was relatively rare to have a capacitor fail.
