HOW TO USE GENERAL TROUBLESHOOTING GUIDE
The General Troubleshooting Guide Table of Contents on the following page indicates how the General Trouble
Shooting Guide is arranged. Match the description of the problem the unit is experiencing with those in the table.
To the left of the problem description is a letter. Locate that letter in the left column of the Troubleshooting Guide.
The information in the center column of the Troubleshooting Guide identifies possible causes for the problem. The
information in the right column explains the tests to perform and/or what action to take to correct the problem.
For Problems “A” through “N”
:
1.
Begin troubleshooting by observing the compartment set points.
2.
If the set-points are normal, initiate Diagnostic Mode by pressing and holding either COLDER key, then press
the UNIT ON/OFF key, then release both keys.
3.
When Diagnostic Mode is initiated, check to see if “Error Codes” are present, being sure to toggle through all the
error and temperature readings by pressing either COLDER key or either WARMER key. (See Thermistor
Location Code Tables below.)
4.
If Error Codes are present, refer to Error Code Troubleshooting Guide on previous pages.
5.
If there are no Error Codes, initiate Manual Component Activation Mode (which lasts five (5) minutes), by press-
ing and holding the desired compartment COLDER and UNIT ON/OFF keys for ten (10) seconds, then observe
the evaporator temperatures.
NOTE:
Verify that the compressor is operating before observing evaporator temperatures. If the problem is in
the refrigerator section, the refrigerator door must be left open for five (5) minutes with the compressor running.
6.
After observing the evaporator temperatures as instructed above, take note of the
“Pointers”
in the first column
of the troubleshooting guide under problems “A” through “D”. The
“Pointers”
list what possible causes to check
based on the evaporator temperatures observed.
For All Problems:
If the unit’s temperature history is needed to help diagnose the problem, initiate Temperature Log Recall Mode as
described below. This allows the preceding fourteen days of the unit’s temperature history to be observed.
a.
To View Compartment Temperature History Only:
Begin with the unit ON. Now, press and hold the desired
compartment WARMER key, then press the UNIT ON/OFF key, then release both keys.
b.
To View Compartment or Evaporator Temperature History:
Begin with the unit on and in Diagnostic Mode.
While in Diagnostic Mode, toggle through the readings until the desired thermistor temperature is displayed on
the LCD. Now, press the WARMER key for that compartment and the UNIT ON/OFF key simultaneously.
