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.
Troubleshooting Guide
NOTE:
If the warmer is not operating properly, do the following
before calling an authorized service agent:
• Verify that the power to the warmer is on.
• Ensure the female end of plug is securely seated in
the warmer and that the male end of the plug is in an
appropriate, functioning outlet.
• Examine the high limit manual reset button. If the
reset button is tripped, reset the button using the
instructions
How to manually reset the warmer
.
• If a temperature calibration adjustment is required,
call service for proper instructions.
• All error codes must be cleared by pressing the circuit
breaker on the back of the warmer to the off (O)
position and allowing the warmer to cool.
Notice:
Do not attempt to repair or service the warmer
beyond this point. Contact the manufacturer for the
nearest authorized service agent. Repairs made by
any other service agent without prior authorization
by the manufacturer will void the warranty.
How to Manually Reset
the Warmer:
1. Locate the manual reset
button at the rear of the
warmer. (The location may
vary from the diagram.)
2. Use a pen, screwdriver or other long, thin implement
to fi rmly push the reset button. The button clicks when
it resets.
If the reset button trips again while the appliance is
running, contact a qualifi ed service technician.
