Samsung Refrigerator Thermostat & Temperature Sensor Parts

Samsung refrigerators depend on precision temperature control to keep food fresh and ice makers working. When your fridge runs too warm, too cold, or cycles constantly, a failed thermostat or temperature sensor is often the culprit. These parts work together to tell the compressor when to run — if either one fails, your whole cooling system gets confused.

OEM Samsung thermostats and thermistors are calibrated for your exact model. Aftermarket replacements frequently cause temperature swings, compressor short-cycling, or frost buildup because they don't match Samsung's control board specifications.

• Thermostat assembly: Controls compressor on/off cycles based on temperature readings
• Thermistor (temperature sensor): Sends voltage signal to control board; incorrect readings cause wrong temperatures
• Fresh food compartment sensor: Monitors fridge section temperature independently
• Freezer section sensor: Monitors freezer temperature and ice maker operation
• Defrost sensor: Triggers defrost cycles to prevent ice buildup

Samsung Refrigerator Thermostat & Sensor FAQs

How do I know if my Samsung refrigerator thermostat has failed?

A bad thermostat or sensor shows itself through temperature extremes: the fridge won't cool at all, runs ice-cold and freezes food, or cycles on and off constantly. You might also notice frost buildup in the fresh food section (defrost sensor issue) or the ice maker stops producing ice even though the freezer feels cold. The compressor may click repeatedly without running, which means the thermostat isn't sending the right signal to start the cooling cycle.

What's the difference between a thermostat and a thermistor on my Samsung?

The thermostat is an electromechanical switch that turns the compressor on when temperature rises above setpoint. The thermistor (temperature sensor) is an electronic part that measures the actual temperature and sends a voltage signal to the control board — the board then decides if the compressor should run. Newer Samsung models rely more on thermistors and digital control boards. Older models use mechanical thermostats. Both can fail independently, so know which one your model uses before ordering.

Can I use a universal refrigerator thermostat instead of the Samsung OEM part?

Not reliably. Samsung's control board expects specific voltage ranges and response times from the temperature sensor. Universal or aftermarket thermistors often trigger false temperature readings, causing the compressor to short-cycle or run nonstop. Always verify your model number and order the OEM Samsung part — it's calibrated for your board and keeps your fridge running right.

Where do I find the model number to order the correct thermostat?

The model number is on a sticker inside the fridge, usually on the back wall above the vegetable drawers or on the side wall. It's also on a label on the back exterior of the unit. Enter that full model number into the search box to confirm the exact OEM thermostat or sensor for your Samsung refrigerator — the wrong part number will not work with your control board.

Samsung Refrigerator Model Number: Where to Look

On Samsung refrigerators, check the label on the inside wall of the fresh food compartment, behind or above the crisper drawers, or on the back exterior of the cabinet. The model number may appear alongside the serial number, so copy the complete model code carefully, including letters and numbers. Enter it in the model number search to pull up the parts matched to your unit. This filters the full Samsung refrigerator parts catalog, not just thermostat or temperature-control parts, so you can review parts that fit your specific refrigerator. Using the complete model number helps avoid mismatched parts, cuts down on ordering errors, and gets your repair moving faster.
