I have an 1850 that has been working properly and maintaining a temperature of -22C. The unit suddenly stopped cooling properly, the chamber will not get below 6C. I removed the trays inside the chamber and the base of the chamber is noticeably cooler, and the side panels just below the glass door are very warm to the touch. What could be causing this issue?

Not driving the stepper motor; doesn't rehome when first powered on.

There is approx. 30VDC from the processor board to the stepper motor driver board. The 30V is good, and the green LED lights on the stepper motor driver board. I couldn't see any indication that there were pulses on Conn 3, but I wasn't sure what to reference them to.

Does anyone have board schematics or experience on this?

The manual knob on our cryotome has ceased flipping the anti-roll plate forward and backward. The plate can be moved by hand but some users fear the knife. Can it be lubricated to work again?
