Defrosting of Flat Top Models Except 4427

Refrigerators defrost automatically with every cycle of the

compressor. The water generated is routed to a pan on the

rear of the cabinet and is evaporated by the heat given off

by the compressor.

Defrosting of Salad Top, Mega Top and 4427 Flat

Top Models

The electronic temperature controller monitors evaporator

temperature and compressor run time to determine the

proper time for a positive defrost cycle. A defrost cycle can

occur as often as every 45 minutes under extremely heavy

usage. When the controller enters the defrost mode the

compressor is shut off and will remain off until the evaporator

coil temperature exceeds 41

°

F or the controller reaches a time

limit of 50 minutes. The defrost cycle can last from a minimum

of 2 minutes to a maximum of 50 minutes.

Service Alert

During normal operation the evaporator fan may cycle

and/or pulse independently of the compressor. Consult

the service manual or contact Technical Support at

1-800-733-8829 if you are unsure of the proper function.
