ELECTRONIC CONTROL ACCURACY
The electronic control is a precise instrument and is
designed to offer trouble-free service. If you suspect
the temperature inside the warming cabinet does not
match the temperature indicated on the digital dis-
play, after stabilizing, follow the instructions
listed below.
1. Make certain the power meets the requirements
of the appliance, voltage and current rating as
indicated on identification tag.
2. Verify the temperature inside the warming cabi-
net with a quality thermal indicator
(digital)
.
A. With the exception of the metal shelves,
completely empty the warming cabinet.
B.
Make certain the sensor, located inside
the warming cabinet at the ceiling, is
completely clean.
C. Suspend the thermal indicator in the center
of the warming cabinet.
D. Allow the temperature, set on the electronic
thermostat, to stabilize for a minimum of one
hour before comparing the digital display
with the reading on the thermal indicator.
DO NOT OPEN THE CABINET DOOR(S) DURING
THE TEMPERATURE STABILIZATION PERIOD.
If the reading on the thermal indicator does not
match the digital display, there may be a problem
with the air sensor. See troubleshooting guide in this
manual; or call the factory service department for
advice.
