Troubleshooting guide

4. Vacation Mode Defrost Interval Interruption: The Vacation Mode Defrost Interval will be

interrupted when either the freezer or refrigerator door is opened.

• The next defrost cycle will occur 8 hours after the door is opened and the ADC will revert to

CRTD (1) = 8 hours.

• If the defrost thermostat remains closed for 19 minutes or more, the ADC will revert the CRTD

back one level.

5. A six minute dwell time occurs after the defrost thermostat opens before the compressor and

condenser fan motor operate.

6. If the defrost thermostat does not open within 29 minutes from the start of a defrost cycle, the

ADC will terminate the defrost cycle automatically.

7. Forced Defrost: To force a defrost cycle to occur, open and close the refrigerator or freezer

door light switch four times in eight seconds allowing ½ second between each action.

IMPORTANT:

• The compressor must be running when forcing defrost.

• The evaporator fan motor is delayed through the defrost thermostat and will not operate until

the defrost thermostat closes.

• To by-bass the 6 minute dwell time after a defrost cycle or to terminate a forced defrost, discon-

nect power to the unit for 30 seconds.

8. When Defrost Mode terminates (the defrost bi-metal opens) the evaporator fan motor will not

operate until the defrost bi-metal resets. This could take approximately five minutes.
