The True 831932 is utilized in many different refrigerator applications. Having a calibrated thermostat is vital to keeping your food products at optimum temperatures and keeping the health department happy when they perform a food safety check. There is on average a three to four degree temperature difference in the cycle of a thermostat opening and closing.

AIR SENSING An air sensing temperature control used in a freezer application will require a defrost cycle with heaters to ensure that the evaporator coil is kept clear of frost and ice.
COIL SENSING An evaporator coil sensing temperature control ensures that the evaporator coil will remain clear of frost and ice by not allowing the compressor to restart until the coil temperature is above the freezing temperature. This is considered an off cycle defrost.

MECHANICAL CONTROL REFRIGERATOR GENERAL SEQUENCE OF OPERATION 1. Cabinet is plugged in. a. Interior lights will illuminate on Glass Door Models only. If lights do not come on verify the light switch is in the “ON” position. Solid door cabinets may or may not have lights that may be controlled by the door switch. 2. The compressor and evaporator fans will start if the temperature control is calling for cooling. (If the compressor does not start, verify that the temperature control is not in the “OFF” or “0” position.) 3. The temperature control may cycle the compressor and evaporator fan(s) on and off together. a. The temperature control is sensing the evaporator coil temperature. b. The temperature control should be set on the #4 or #5. c. The warmest setting is #1, the coldest is #9, and #0 is the off position. d. The thermometer is designed to read and display a cabinet temperature not a product temperature. The thermometer may reflect the refrigeration cycle swings of up and down temperatures. The most accurate temperature on a cabinet's operation is to verify the product temperature. 4. There is not a defrost timer as the temperature control will initiate the off-cycle defrost during each refrigeration cycle. a. At this time, the compressor will and the evaporator fan(s) may turn off. Defrost heaters are not installed on refrigerators and therefore will not be energized. b. After the evaporator coil temperature has been reached, as determined by the temperature control, the compressor will restart. 5. There may be a timer located on the condensing unit base. This timer is not used for a defrost event. The timer will change the rotation of the reversing condenser fan motor.

(If the compressor does not start, verify that the temperature control is not in the “OFF” or “0” position or the cabinet is not in a defrost event.) a. The evaporator fan(s) will remain off until a specific temperature of the evaporator coil is reached. 3. The temperature control may cycle the compressor and evaporator fan(s) on and off together. a.
