set point
Cavity temperature
higher than set point
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 a 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 o 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 ( uid warmers only). Adjust if necessary.
• Ensure that the compartment fan motor is operating ( 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.
