NOTE:
If the warmer is not operating properly, check the following
before calling an authorized service agent:
Verify that the power to the warmer is on.
If applicable, ensure the female end of plug is securely seated in the
warmer and that the male end of plug is in an appropriate,
functioning outlet.
If applicable, examine the fuses. Replace the fuses, refer to topic How
to Replace a Fuse.
If applicable, examine the high limit manual reset button. If the high
limit manual reset button is tripped, reset the warmer, refer to topic
How to Manually Reset the Warmer.

All non-critical codes can be cleared using the standby button.

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.
Action required
Cavity temperature is higher than the set point temperature.
◾Allow cavity to cool to set point temperature.
Sensor is shorted. Software disengages heating pads. Acknowledge error
by pressing the standby button. If error persists, a qualified service
technician should test the sensor.
◾Test the sensor. Detach the sensor from the warmer. Use an Ohm meter
to measure the resistance of the sensor. Check the sensor at 25°C (77°F).
If the reading is 10 KOhm ±1.5 KOhm, replace the display. If the reading
is ±2 KOhm, replace the sensor.
◾Check the wires for integrity. Inspect the connections at the control and
terminal block to ensure proper and secure connections. If necessary,
re-secure the faulty connections.
◾Contact service if error persists.
