I was hoping that someone on here has experience with Suhner grinders. I have a Suhner UTC that stopped working, once triggered it will run up to speed and shut off until the power is cycled again. Suhner of course has nothing available for manuals or information for troubleshooting that I can find, I think it may be the thermal overload protection but I cannot confirm. Has anyone out there had any experience? The Suhner rep told me to send it in for inspection but there is an "up to $100 troubleshooting fee".
