MM-1065 (MN-29614) • Rev 4 • 06/16 • Pedigo Fluid Warmer
Troubleshooting
Code Description
Action Required
door Door left open for
more than 3 minutes
• Close the door.
• Verify door switch operation and replace if necessary.
E-10 Cavity Air
Sensor Shorted
• Detach the sensor from the terminal block. Use an Ohm meter to measure the
resistance of the sensor. Check sensor at 32°F (0°C) using a container of ice water.
Ohm reading should be 100. If Ohm reading is +/- 10, replace sensor.
• Check wires for integrity. Check for proper and secure connections at the electronic
control and terminal block. If necessary, re-secure the faulty connections.
• If error continues call service
E-11 Cavity Air
Sensor Open
• Detach the sensor from the terminal block. Use an Ohm meter to measure the
resistance of the sensor. Check sensor at 32°F (0°C) using a container of ice water.
Ohm reading should be 100. If Ohm reading is +/- 10, replace sensor.
• Check wires for integrity. Check for proper and secure connections at the electronic
control and terminal block. If necessary, re-secure the faulty connections.
• If error continues call service.
E-30 Under Temperature
(Blanket warmers
only)
• Blanket chamber temperature has been lower than the set temperature for 90 minutes
or longer.
• Check that door is closed.
• Not preheated due to an overloaded cavity.
E-31 Over Temperature
• Appliance may be overloaded. Redistribute inventory. Do not exceed height of insert.
• Check sensor at 32°F (0°C) using a container of ice water. Ohm reading should be 100.
If Ohm reading is +/- 10, replace sensor.
• Check wires for integrity. Check for proper and secure connections at the electronic
control and terminal block. If necessary, re-secure the faulty connections.
• Relay may be defective.
• If error continues, call service.
E-50 Temp Measurement
Error
• Call service.
E-60 Real-Time
Clock Error
• Appliance may have been unplugged for an extended period of time.
• To resolve, turn circuit breaker switch to on position for 1 minute, then turn circuit
breaker switch to the off position for 5 seconds, and then back to ON. The error
message should no longer appear in the display.
• In order for the appliance to fully recharge, it should remain plugged in and power
circuit breaker switch turned on for at least 24 hours aft er resetting.
• Upon resolving an E-60 error, check 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 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
• Stored offsets corrupted. Offsets reset to 0. Control may need a recalibration. Possible
bad EEPROM.
• If error continues, call service.
E-90 Button Stuck
• A button has been held down for >60 seconds. Adjust electronic control. Error will
reset when the problem has been resolved.
E-99 Hardware
Over Temp
• Inspect connections and condition of high limit bimetal thermostat and the fan
switch (fl uid warmers only). Adjust if necessary.
• Check operation of cavity fan motor (fl uid warmers only). Air movement from the
cavity fan should move the safety sail switch to the closed position. Adjustment to
the fan may be needed or replacement of the fan motor.
• If error continues, call service.
