Manual Reset Thermostat
The manual reset is a device that provides thermal protection for the platen. In the event that the main
controller or power relay fails to regulate the heat on the platen, the manual reset thermostat will break the
electrical connection to the platen. The control, the motors, the conveyors, and the fans may all continue to
operate, but no more heat will go to the platen. The manual reset thermostat will prevent any power from
going to the platen until a person resets it.
If the manual reset thermostat trips (disallows heat to the platen), this may indicate an extreme failure of
another device. If this thermostat trips more than once, it is important that you contact an authorized APW /
Wyott technical service technician.
To reset the thermostat, locate the thermostat at the rear of the toaster. There is a black knob near the power
cord and the rating label. Unscrew the black cover (you may need a screwdriver). Push in the button that it
is covering. Replace the black cover (hand tight).
