Wheel Stuck On, Not The Pedal

Recommended Posts

The other day I heard a weird constant noise coming from my studio, I thought it was one of my many vents or fans left on and didn't think much about it.

 

The next day I found my wheel to be left on (oops) and spinning at top speed. I rushed over to fix the pedal but it was in the off position.

 

Today I opened up the pedal to make the adjustment to the little plastic lever, I assumed this was the problem, having dealt with this flimsy contraption many times, but the lever seems to be working properly. No matter which position it's in the wheel goes top speed. 

 

Anyone had this happen before? Is there another area that regulates speed besides the pedal that I could check? It's a Brent CXC from the late 80's

Your CXC is not that old-I use one from the early 80's.

If your foot pedal controls (the blue and red small wheels do not fix this) by turning with a  small screwdriver when wheel is on its moist likely your control board. I would call Amaco/Brent and talk to one of the Techs about the symptoms .

I have had this issue once and for me it was the board-Thats not to say its your fix-it was mine.

All Brent wheels (no matter what type A-B-C-CXC-prior to about 1999 or 2000 use this control board-its overpriced but their cheapest one

Here is that link for the board

Just to follow up, I spoke with AMACO about this issue and Mark was correct about the part that needs to be replaced. If the wheel spins at top speed with no control from the pedal, the part that needs replacing is the Control D-30 110V CXC HI Speed. AMACO said this is one of the most commonly replaced items on these older wheels (pre 2000) so they may need to be replaced in time. They also said that they can be zapped by a power surge if you wheel is left plugged in. Another note, be careful when troubleshooting this issue, if you strain the little red and blue dials in the foot pedal they will need to be replaced as well. They should only turn about 3/4 of a turn when working properly, never over turn them.

 

Thanks Mark!

I own 5 Brent wheels -bought my 1st one from Robert Brent himself in 1970-71?-He ran the business then out of an old house turned into a wheel manufacturing plant. Since then I have done just about everything to that wheel as well as the 4 others I have over time.

I usually keep that board as well as the foot pedal control in stock here at my pottery .Right now I have an entire motor ,controller and foot pedal from e bay as spare parts.
