SERVICE MANUAL

Refrigerator
Theory of Operation
Compressor & Evaporators
The refrigerator has two evaporators, but only one compressor, charged with R600a refrigerant. The Fresh Food and Freezer compartments are sealed off from each other. As there is no transfer of air between the two compartments, the temperature management for each compartment is accomplished by the individual evaporators and sensors. A refrigerant valve is used to regulate the flow of gas between the two evaporators.
Display
The Display is the operational interface for the customer. For information about each key and option, see the description below
Temperature Sensors
There are six thermistors on this product – One for the Outside top of refrigerator (Ambient), One for the Special fridge (Air ),Two for the Fresh Food (Air & Evaporator), Two for the Freezer (Air & Evaporator).All of these sensors are NTC thermistors.Temperature information is transmitted to the main board via changes in their resistance. These thermistors ensure that the product operates according to the parameters set by the system software.
Heating Elements
There are six heating elements on this refrigerator – a Fresh Food Heater (evaporator), a Freezer Heater (evaporator), a Fresh Food Drain Heater (not accessible),Two Fill Tube Heaters, an Ice Maker Heater (The Flapper, Fill Tube Heaters and Ice Maker Heater are in a parallel circuit),The Defrost and Drain Heaters are in a parallel circuit. The refrigeration and freezing defrosting are synchronized, and the maximum defrosting time is limited to less than 50 minutes. When the sensor detects the temperature 46/8 during defrosting, the defrosting will be stopped. After defrosting, delay 5 minutes for the compressor to start, and 3 minutes for the fan to run after the compressor starts.
Fans
There are three fans on this product – a Fresh Food Fan, a Freezer Fan, a Condenser Fan,All fans are 12VD. C, and directly powered by the Main Control Board. The Fresh Food and Freezer Fans ensure proper air movement in their respective compartments. The condenser assembly in the compressor area is used to expel the heat pulled from all compartments. The Condenser Fan accelerates this heat transfer.
Ice Makers & Water Valves There are a 115VAC motor twist the ice trays to eject the ice cubes. A water valve is used to send water to the ice trays after each ice harvest. No flow meter is used to measure the water amount. A solenoid on the main water valve assembly is energized for the time set by the system software. A secondary water valve, located inside the partition between the crisper drawers, is energized when the microswitch at the dispenser is depressed.
Lights
12VDC LED light boards are used to illuminate Freezer and Fresh Food Compartments. Reed switches at the top of the doors activate the lights when a door is opened.
Controller
All the components listed above are operated by the Main Control Board located at the top of the product. Access to this, and all other components, is explained in the disassembly section of this manual.

High Temp Erro
When the temperature collected by the freezing sensor reaches set 39(+4), if the temperature rises 30(-1), the high temperature alarm will buzz twice consecutively, and the freezing temperature LED light will flash; Touch any button, the over-temperature alarm sound will be canceled, but the freezing temperature LED light will continue to flash; The alarm will stop only when the temperature collected by the sensor is less than 28(-2).
If the over-temperature alarm continues after rebooting the appliance, it is necessary to check whether the refrigeration system is blocked, and whether the compressor and fan are working properly.

The refrigerator’s operating sounds varies over time. The refrigerator makes vibration or other strange noises.
Evaporator Fan is noisy.
Condenser Fan is noisy.

The operating sounds will vary according to different cycles, food volume and environmental conditions. Various components make vibration sounds, such as when water valves energize. Also gas flowing through refrigerant lines can make gurgling noises. And popping and sizzling sounds can occur during the defrost cycle. The fan blade may be irregular.
Fan blade may be hitting something.
Fan speed may be too high.
The fan blade may be irregular.
Fan blade may be hitting something.
Fan speed may be too high
Dust and debris may have ruined fan motor

This is normal.
As long as both compartments are maintaining proper temperatures, these sounds are normal.
Remove evaporator cover and inspect fan for irregularities. Replace if necessary. Remove evaporator cover and inspect fan area for any obstructions. Adjust fan or remove obstructions. Check fan speed for proper RPMs. Fan may be noisy if RPMs are too high. Replace fan motor, if so. Remove compressor cover and inspect fan for irregularities. Replace if necessary.
