Clearing Non-Flashing "SERVICE" and Error Codes
If Error Codes are observed in Diagnostic Mode, a non-flashing SERVICE icon will appear on the LCD when
Diagnostic Mode ends, indicating error codes are still stored (See Figure 3-38). To clear a non-flashing SERVICE
icon and the error codes, the problem must be corrected and the unit must be ON, then:
• On a model UC-24C: Press the Freezer WARMER and COLDER keys for fifteen (15) seconds, and the error
codes are cleared. (See Figure 3-39)
• On a model UC-24B, UC-24R or UC-24RO: Press the Refrigerator WARMER and COLDER keys for fifteen (15)
seconds, and the error codes are cleared. (See Figure 3-40)
