COMPRESSOR/ELECTRICAL SPECIFICA TIONS 2075DWRR COMPRESSOR PINS To measure start winding resistance, measure across the C-S pins. To measure run winding resistance, measure across the C-R pins. These pins should never measure any resistance to ground. This would indicate a shorted compressor .
REFRIGERA TION SYSTEMS Normal V apor/Compression Cycle Refrigeration • Refrigerant is pumped from the compressor to the condenser as a high pressure, high temperature vapor . • As the refrigerant cools in the high pressure condenser , the vapor condenses to liquid.
THERMIST OR The thermistor senses the compartment temperature. This is used in conjunction with the control board to determine the length of the refrigeration cycle. Thermistors generally fail due to moisture or physical damage. SER VICE NOTES 2075DWRR The 2075DWRR has the same basic refrigeration system as the 2075R with a few exceptions.
THE ELECTRONIC TEMPERA TURE CONTROLLERS 2075DWRR • The controller has a four minute minimum off-cycle regardless of the thermistor status. • The controller has a 4° differential built into it for the refrigerator thermistor .
2075DWRR The temperature controller is located in the top drawer . The LED display shows the temperature set point and is calibrated in degrees Fahrenheit. The controller is factory programmed for a set point of 38°F which will show when the unit is first powered-up.

COMPRESSOR/ELECTRICAL SPECIFICA TIONS 2075DWR WC COMPRESSOR PINS To measure start winding resistance, measure across the C-S pins. To measure run winding resistance, measure across the C-R pins. These pins should never measure any resistance to ground.
REFRIGERA TION SYSTEMS Normal V apor/Compression Cycle Refrigeration • Refrigerant is pumped from the compressor to the condenser as a high pressure, high temperature vapor . • As the refrigerant cools in the high pressure condenser , the vapor condenses to liquid.
• From the dryer , the refrigerant flows through the capillary tube which meters the liquid refrigerant to the evaporator . The pressure of the refrigerant is reduced to the evaporating or low side pressure. • The reduction of pressure on the liquid refrigerant causes it to boil or vaporize until it reaches satura- tion temperature.
The top and bottom valve can never be open at the same time. After initial startup whichever compartment calls for cooling first, will have priority . Once the setpoint is achieved the other compartment will be cooled if necessary .
THE ELECTRONIC TEMPERA TURE CONTROLLERS 2075DWR WC The temperature controls are integrated in the top, front drawer panel. They consist of an LED display and touch sensors for each drawer and a touch sensor to control the lighting (“ ”, “ ” and “ ”).
2075DWRWC 28 Design ■ Features ■ Performance INTERIOR LIGHTING (2075DWR WC) The interior lighting can be controlled by the controller . Each time the light “ ” symbol is touched, the lighting is scrolled through the following options: T ouch once – Both compartment lights on.

3 Drawers will not close properly • The drawer slides contain a self-closing feature which engages when the drawer is about 1 inch from being closed. At the point the closers engage, there may be some resistance. If this resistance is hard to overcome, try closing the drawers with more for ce a couple times and then try slowly again.

SER VICE NOTES CO2075DWR The CO2075DWR has the same basic refrigeration system as the CO2075F with a few exceptions. • The compressor is an Embraco EMI70HER. • The electro-mechanical gas bulb is replaced with an electronic controller which features a digital temperature display .
When checking the thermistors to see if they are reading accurately , it is common to place them in an icebath to see if they read 32°F . Do not place them directly in the water . Use a plastic bag to protect them from moisture. The freezer and ice maker should read 32°F in icewater , however the refrigerator thermis- tor should read 36°F .
