Damper Control

• Refrigerator temperature setting and thermistor value will determine if damper control heater switch is to be open or closed.

• Damper closes at 9°C (48°F).

• Damper opens at least 1/4" when minimum voltage is applied at 4°C (40°F) ambient.

An open thermistor or thermistor circuit will result in failure of refrigerator to cool.

Shorted thermistor will cause refrigerator to run 100 percent of time except for defrost.

• Freezer temperature setting and thermistor value will determine if compressor/condenser fan and evaporator fan switches are open or closed. Compressor/condenser fan switch must be open for 6 minutes before switch can close again (compressor dwell time).

• Cut-out and cut-in temperature values must be reached and maintained for 15 seconds before output state will change (digital delay).

• Refrigerator and freezer control calibration can be adjusted in Program Mode B.

Electronic Functional Description

Adaptive Defrost Operation

Defrost occurs after predetermined length of compressor run time. Compressor run time between defrosts changes, or adapts, depending upon recent history of defrost lengths (time it takes for defrost terminator to open after defrost heater has been turned on).

• Defrost terminator opens at 9°C (48°F) and closes at -9°C (15°F).

• Compressor run time between defrosts (CRTD) will be one of 3 values under normal operation: CRTD 1 (6 hours) or CRTD 2 (9 hours) or CRTD 3 (12 hours).

If defrost length is low (DT-LO defined as 21 minutes) indicating small frost load, CRTD for next defrost cycle is advanced to next level.

If defrost length is high (DI - HI defined as 24 minutes) indicating large frost load, CRTD for next defrost cycle is lowered to next level.

If defrost length is between 21 and 24 minutes, CRTD for next defrost cycle remains the same.

Initial value at power up CRTD 0 is 3 hours.

• Vacation Mode CRTD equals 72 hours. Vacation Mode CRTD is interrupted with door openings. Defrost interval will revert back to interval before Vacation Mode. Three things must occur to reach Vacation Mode CRTD:

1) Defrost interval must be CRTD 3 (12 hours).

2) Both refrigerator and freezer doors must have

remained closed since last defrost cycle.

3) Defrost thermostat must have opened in less

than 21 minutes during last defrost cycle.

• Six minute dwell time occurs after defrost terminator opens before compressor and condenser fan motor will operate. Ten minute dwell time occurs after defrost terminator opens before evaporator fan motor will operate. Dwell time can be bypassed by disconnecting power to the unit for 30 seconds.

• Conventional defrost can be selected in Program Mode B.
