Troubleshooting (continued)
CHECK
1. Check heater temperature.
2. Change compression settings. If both crowns and
heels are light, increase compression setting (the
higher the compression setting, the greater the
compression).
3. If only one side is light, adjust the compression
wall by removing the cotter pin and adding
washers to move the wall to the appropriate
position. Replace cotter pin.
1. Turn power off and allow the toaster to cool.
2. Carefully remove the side panels in order to view
the heater relays.
NOTE: There are two control panels on the front of
the unit. The yellow control panel on the left controls
the heaters for the front chamber. The green control
panel on the right controls the heaters for the rear
chamber and the buffered bun landing zone.
3. Turn unit ON and immediately press and hold the
PRINCE CASTLE Logo button, the
INFORMATION button, and the PRODUCT
button. Hold these buttons until the display reads:
"Heater Test".
4. Press the INFORMATION button.
5. The LED on relay 1 should begin blinking and
corresponding heater should begin to heat. Verify
that heat is being generated by the heater.
6. Press the down arrow to move relay 2 and heater
2. Verify that the relay is operating correctly. The
display will read the current temperature for this
heater. Verify that heat is generated by the heater
and that the display temperature increases by at
least 5 degrees. Press the down arrow to move to
the next relay and heater.
NOTE: Heaters 1 and 5 are IR heaters and do not
have a temperature probe. Therefore, the display will
not show a temperature setting for these heaters,
only for 2, 3, 4 and 6.
7. Repeat each of these steps for the remaining
relays and heaters.
8. If necessary, repeat these steps for the other
toaster chamber.
