HOW TO USE THE GENERAL TROUBLESHOOTING GUIDE
The General Troubleshooting Guide Table of Contents (above) indicates how the 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. Information in the
center column identifies possible causes, while information in the right column explains the tests/Actions to perform.
NOTE: For Problems “A” through “K,” “S” and “V”:
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. (See Thermistor Location Code Tables below.)
3. R ecord the compartment and 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 5 minutes with the compressor running.
4. 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.
