Electronic Control
Error Indication
The following error conditions are monitored by each electronic control assembly:
1. Thermistor open or shorted. Adefective thermistor will require that the affected electronic control assembly
be replaced.
2. Stuck Key (the key appears to be pressed for longer than 30 seconds).
3. Low Voltage (AC line voltage has dropped below 90 volts).
If any of these errors occur, the display will flash an "E" at one second intervals and the control will go into Fail Safe
Mode.
Fail Safe Mode
While in Fail Safe mode, the compressor will run constantly with a 30 minute defrost cycle every 12 hours.
Stuck Key
If either key is held in for more than 30 seconds the control enters fail safe operation.
Exiting Fail Safe Mode
Once a failure is resolved (thermistor, stuck key or low voltage), the control resumes its normal operating mode
under the setting it was at before the error occurred.
