F. Control Generation 2 – Check for 24 Vdc from control board to motor relay (R3). If relay is
getting 24 Vdc, check for 208 volts on output side of relay. If no 208 volts, replace relay.
6. PROBLEM: Product is over or under toasted.
SOLUTION:
OPERATOR CHECK:

gap) turn knob counter-clockwise; to raise (increase gap) turn knob clockwise.

D. Make sure conveyor belts are not binding.
E. Check drive system for loose sprockets.

controller to the platen. You are looking for cycling. Also verify that the temperature controller
has power.
