DIAGNOSTICS

A spanner symbol and LCD fault code will appear automatically if there is a fault in the temperature
measuring system, defrost system, fans or low ambient heater. (Refer diagram below.)
When the PC door is opened, an alarm will sound. The number of beeps also indicates the fault
code. Pressing any of the control buttons can deactivate these alarms.
Example: When a fault develops, the LCD fault code appears with the spanner.
After rectifying the problem, the fault code and spanner will disappear. Faults are only rectified
when that feature is used. So in the case of a defrost fault, the code will remain until a defrost is
initiated and it is successful.
