2075DWRR

THERMISTOR

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.

SERVICE NOTES

2075DWRR

The 2075DWRR has the same basic refrigeration system as the 2075R with a few exceptions.

•The compressor is a high efficiency Embraco EMU30HSC.

•The electro-mechanical gas bulb is replaced with an electronic controller. The controller features a digital temperature display and control with two LED indicators and three touch pad buttons.

•The mullion between the two drawers has a low wattage “anti sweat” surface heater to prevent con- densation on the mullion. Additionally, there is an anti-frost heater on the drain trough.

A thermal cut-out is mounted on the base, where the thermostat is normally mounted. This energy saving feature cuts-out the “anti-sweat” heater as well as the trough heater in high ambient tempera- tures, when in most conditions, the mullion would normally be warmed by ambient air.

•There are two interior lights and light switches. The switches are mounted in a switch box in the rear interior of the cabinet and the lights, in a housing in the top front of the drawers.
