Temperature/Resistance/Voltage Chart for Samsung Refrigerators Sensors

FREEZER TEMPERATURE CONTROL BY THE ICE MAKER

Interior Temperature of the freezer will be set to -14 degrees Fahrenheit until the ice bucket is full. When the ice

bucket is full, the freezer will maintain original set temperature. Also, whenever the ice is used, the freezer will

again set to -14 degrees Fahrenheit. Selecting "Ice Off” will allow the freezer to be controlled by the set tem-

perature. If water is not hooked up, the freezer will always be at –14 unless “Ice Off” is selected.

Shattered Ice – Flex Tray

When all ice shatters, it's because of a bad

tray or ice cube temp that is too cold (lower

than -5 degrees). In some areas, there are

water issues that can also cause shattered

cubes. The temp in the freezer should not

have any effect on this issue, as long as it’s

below 1.5 degrees F, as a properly installed

sensor will not read the freezer temp, only the

water/ice temp.

Check the Ice tray for defects in the plastic.

Ice that is too cold will shatter during

harvest. This can be from the (1) sensor not

reading the correct temp (2) or the sensor not

mounted correctly (3). By programming the

icemaker offset value to a lower number (4),

the board not understanding the reading.

To check the sensor, you must check the tray

temp (not air temp) and compare it to the sen-

sor reading. The sensor should read 3.7 volts

at the main board connector when the cube

temperature is 1 degree. After the fill, the sen-

sor will read water temp 1.5 to 2.2 volts.

To clear offsets, put unit into Diagnostics

mode.

Please note, some shattering is normal for

a flex tray icemaker.

FLEX TRAY Ice Makers

When the initial power is applied, the ice tray will stand by for 2

hours. After the 2-hour standby time, the Ice Maker Sensor will check

the temperature , when it is lower than 1.5Ԭ for more than 5 minutes,

it will do a harvest, with or without ice in the tray, then fill with water.

58 minutes after water is supplied to the Ice Tray, the Ice Maker

Sensor temperature will be checked. When the Ice Maker Sensor

maintains lower than 1.5Ԭ for 5 minutes, it completes the harvest

(if the ice bin is not sensed as full).

Thermistor senses temperature to determine water fill on newer units

Filling the tray

After the water fill is completed, the ice maker sensor will evaluate the

water volume one and a half minutes later. When it detects no or low

water level, it will add more water. First supply time will be 1.5 sec,

next one will be 1 sec and the last will be 2 sec.

DEFROST

This model series uses a Defrost Heater in the Fridge and the Freezer compartment that is part of the Evaporator Coil.

NOTE: Evaporator Covers May Break If Removed While Frozen To Coil. They must be replaced if there is any damage,

as this will cause “ice” to form at top or bottom of the evaporator coil or in the drains.
