The electronic thermostat is a precise
instrument and is designed to offer trouble free
service. If you suspect the temperature inside
the holding compartment does not match the
temperature indicated on the digital display,
follow the instructions listed below.
1.
Check to make certain the unit voltage
matches the power source. A power source
less than that required to operate the unit
will result in inaccurate temperatures.
2.
Verify the temperature inside the
holding compartment with a qualify
thermal indicator.
A.
With the exception of the wire
shelves, completely empty the
holding compartment.
B.
Make certain the holding cabinet
sensor, located inside the holding
compartment at the left side of the unit,
is completely clean.
C.
Suspend the thermal indicator in the
center of the holding compartment.
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.
