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 quality thermal indicator.

a. Completely empty the holding compartment.
b. Make certain the holding cabinet sensor,

located inside the holding compartment, 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 DRAWER(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.
