At 90 degrees farenhiet resistance should be approx. 560 ohms on each dev and fix temp probes. Move wires while measuring to see if resistance changes ie bad wires. Motor overload problem: check to see if racks are binding and connections at opto coupler

I believe you have a broken dev temp sensor. Happened here tooooo many times. Were thae racks removed during the move? If not, may have happened there. If so, could have happened removing or replacing the rack into the tank.

Try swapping your fixer sensor into the Dev tank, they are the same unit. The machine will run with the Fix sensor (the Dev sensor) unplugged.

Good luck!
