Display Error Code Reference:
The microprocessor in the control continually monitors critical refrigeration system
components for proper operation. If component parameters exceed normal operating
specifications, the display will automatically flash the respective error code as follows:
Compressor fault, (high/low amps).
Condenser fan motor fault, (high/low amps).
Evaporator thermistor “sensor B” fault, (out-of-range).
Display thermistor “sensor A” fault, (out-of-range).
Power line fluctuations may cause an error code to be displayed with no product fault.
Therefore, the first time an error code appears, please clear the code by holding and
pressing 4 times. If the product is at fault, the error code will appear again, and you
should contact your Dealer or Viking Customer Service to schedule service by a
