Samsung Refrigerator Error Code 37

Error code 37 on a Samsung refrigerator indicates a low register error in the convertible zone. This means the control board is detecting that the temperature sensor in the convertible compartment is reporting a value that falls below the acceptable threshold. It typically points to a faulty thermistor, a wiring issue, or in less common cases, a control board problem.

Error 37 can be a concern for food safety if the convertible zone is not maintaining proper temperatures as a result of the fault. If food in that compartment seems warmer or colder than expected, you should move perishables to another section of the refrigerator until the issue is resolved. The error itself does not pose an electrical or fire hazard.

A reset may temporarily clear the error code from the display, but if the underlying hardware fault remains, the code will return. To reset the refrigerator, you can unplug it for several minutes and then restore power. If error 37 reappears after the reset, the thermistor, wiring, or control board needs to be properly diagnosed and repaired rather than relying on repeated resets.

Some causes of error 37 are approachable for a knowledgeable DIYer. Inspecting and reseating the wiring connectors to the convertible zone thermistor requires only basic tools and no special skills. Testing the thermistor with a multimeter is also manageable if you are comfortable with basic electrical checks. However, replacing the control board is more involved and is generally better left to a technician.

Repair costs vary depending on the root cause. Replacing the convertible zone thermistor typically falls in the range of $50 to $150 including the part and labor. If the main control board is at fault, costs can range from $150 to $400 or more depending on the model and local labor rates. A diagnostic service call alone generally runs $75 to $125.
