Cavity temperature is higher than the set point temperature.
• Allow cavity to cool to set point temperature.
• Not applicable on warmers with control CC-34765.
door
The door has been
open for more than
3 minutes.
• Close the door.
• Verify that the door switch is operating. Replace the door switch if necessary.
E-10
The compartment
air sensor is
shorted.
• Detach the sensor from the terminal block. Measure the resistance of the sensor with
an ohmmeter. Test the sensor at 32°F (0°C) using a container of ice water. The ohm
reading should be 100. If the ohm reading is +/- 10, replace the sensor.
• Inspect wires for integrity. Ensure proper and secure connections are made at the
controller and the terminal block.
• If the error continues call service.
E-11
The compartment
air sensor is open.
• Detach the sensor from the terminal block. Measure the resistance of the sensor with
an ohmmeter. Test the sensor at 32°F (0°C) using a container of ice water. The ohm
reading should be 100. If the ohm reading is +/- 10, replace the sensor.
• Inspect wires for integrity. Ensure proper and secure connections are made at the
controller and the terminal block.
• If the error continues call service.
E-30
Under Temperature
(Blanket warmers
only)
This error occurs when the blanket chamber temperature is lower than the set
temperature for 90 minutes or longer.
• Ensure that the door is closed.
• If the compartment is overloaded, redistribute the inventory. Do not exceed the
height of the insert.
E-31
Over Temperature
• If the compartment is overloaded, redistribute the inventory. Do not exceed the
height of the insert.
• Measure the resistance of the sensor with an ohmmeter. Test the sensor at 32°F (0°C)
using a container of ice water. The ohm reading should be 100. If the ohm reading is
+/- 10, replace the sensor.
• Inspect wires for integrity. Ensure proper and secure connections are made at the
controller and the terminal block.
• Replace the defective relay.
• If the error continues, call service.
E-50
Temperature
Measurement Error
• Call service.
E-60
Real-Time
Clock Error
• Has the appliance been unplugged for an extended period of time?
• To resolve the error, set the power circuit breaker switch to the ON (I) position for
1 minute, then set the power circuit breaker switch to the OFF (O) position for 5
seconds, and then set the power circuit breaker switch to the ON (I) position. The
error message should no longer appear in the LED screen.
• In order for the appliance to fully recharge, the appliance should remain plugged
in and the power circuit breaker switch in the ON (I) position for a minimum of 24
hours aft er resetting.
• Upon resolving an E-60 error, ensure that the date and time are correct.
E-61
Real-Time
Clock Error
• Call service.
E-80
EEPROM Error
• Ensure that all temperature and times are properly set.
• If the error continues, call service.
E-81
EEPROM Error
• Call service.
E-82
EEPROM Error
• Call service.
E-83
EEPROM Error
• Call service.
E-87
EEPROM Error
• Ensure that all calibration off sets are properly set.
• If the error continues, call service for proper calibration instructions.
E-90
A controller button
is stuck
• A controller button has been held down for longer than 60 seconds. Adjust the
controller. The error will reset when the problem has been resolved.
E-99
Hardware is
over temperature.
• Inspect the connections and the condition of the high-limit bimetal thermostat and
the fan switch (fl uid warmers only). Adjust if necessary.
• Ensure that the compartment fan motor is operating (fl uid warmers only). Air
movement from the compartment fan should move the safety sail switch to the
closed position. Adjust the fan or replace the fan motor.
• If the error continues, call service.
