ADDITIONAL DIAGNOSTIC MODE NOTES:
• If “Sh” and “r” appear in the LCD when initiating Diagnostic Mode (See Figure 3-63), the unit is in Showroom Mode
which was covered earlier in this section.
• If “EE” is observed in the left display area during Diagnostic Mode, the thermistor in that location is open, shorted,
unstable, or not present (See Figure 3-64).
• There is currently no thermistor in the drawers, so “EE” will appear at left of the “dr” (See Figure 3-65).
• There is currently no thermistors on the condenser, so “EE” will appear at left of the “Cn” (See Figure 3-66).
• The ambient thermistor is part of the control board. It is not a separate component.
