platen and reconnect to the
controller.
Digital controller
beeping and is
overheating.
The mechanical relay on the switched
side is not opening to regulate
temperature. Hold TEMP button
then depress either the down or up
arrow (zone 1, lower platen, zone 2,
left upper platen and zone 3, right
upper platen.) RLY will display on
problem zone indicating the damage.
Replace the mechanical relay.

Either platen is not
heating but the
digital controller is
on and appears to be
functioning.
If the mechanical relay(s) on the coil
side are receiving 12vdc indicates the
controller is functioning properly. If
there is no voltage on the switching
side of the relay to the heaters, the
relay is not working properly.
Replace the mechanical relay.

Beeper is not
functioning.
Beeper has failed.
Replace control board.
A8
One of the three
heater platens not
close to set point.
The offset function in the controller's
setting needs to be adjusted to
achieve proper shade of toast.
Call (800) 624-6717 for
instructions.
----
One heating zone is
not reaching setpoint
and another heater is
overheating.
Sensors maybe crossed.
Make sure each sensor is
connected to its prospective
position on the terminal block
and back to the controller.
----
Setpoint is reached
but slightly off in
temperature.
Offset may need to be calibrated and
adjusted.

Heater platen is
overheating.
1. The mechanical Relay may be
stuck in the closed position (zone 1,
lower platen #1 labeled on this relay,
zone 2, left upper and zone 3, right
upper).
2. If you are receiving 12vdc on the
coil of the relay, the controller is
properly functioning.
Use an Ohm meter for a
continuity check must check at
the cold pins of the heater (where
the heater wire is brazed at
the cold pin. This will eliminate
any other failure before the
heater element validating the loss
off continuity at the source the
heater element.

to the lower platen.
Parallel lever not attached either in
the rear out on the upper heater
