How does an refrigerator adaptive defrost control work?
A refrigerator adaptive defrost control is designed to turn on the defrost heater only when necessary. It is an electronic control that monitors the frost build up on the evaporator using thermistors. When the adaptive defrost control senses a frost build up on the evaporator that will restrict airflow, it closes a relay to send power to the defrost heater melting the frost away.
How does a refrigerator six hour defrost timer work?
A six hour defrost timer is a 6 hour run time with a 21 minute defrost cycle timer. That means that for every 6 hours of compressor run time, the defrost heater could be on for 21 minutes. That makes this defrost timer ideal for areas with extreme humidity or on refrigerators with excessive door openings that cause too much frost build up on the evaporator. |
