Samsung Range Error Code Over Temperature Error

Top sensor temperature rises excessively

Samsung codesSamsung range codes

Top sensor temperature rises excessively — estimated ceramic glass surface temperature exceeds 250°C (e.g., empty cookware operated on burner).

First step from the service manual

Allow hob to cool; check if induction was operated with empty cookware; check top sensor wire connection and resistance.

What Over Temperature Error means on a Samsung range

The Over Temperature Error on a Samsung induction range activates when the top sensor detects that the ceramic glass surface temperature has climbed above approximately 250°C. This threshold is a protective limit built into the induction control system to prevent damage to the glass surface, the underlying induction coil assembly, and any cookware or food items on the hob. The top sensor is a thermistor positioned beneath the ceramic glass that continuously monitors surface temperature and reports readings back to the main control board. When that reading exceeds the programmed limit, the board triggers this error and shuts down the affected burner zone.

The most frequent cause is operating the induction burner with empty cookware or with a pan that has boiled completely dry. Induction heating is highly efficient and transfers energy very rapidly into compatible cookware. Without the thermal mass of food or liquid absorbing that energy, the pan and the glass surface beneath it can reach critical temperatures within minutes. The control system flags this condition to protect the appliance from thermal stress damage.

Diagnosing this error requires confirming first whether empty cookware was the trigger, then allowing the unit to cool completely before attempting any further checks. Once cooled, the top sensor wire harness connection should be inspected for looseness, corrosion, or heat damage. The sensor resistance should also be measured and compared against expected values for the operating temperature range. A sensor that reads open circuit, short circuit, or wildly out of specification resistance will cause erratic temperature reporting and may trigger false over-temperature faults even under normal cooking conditions.

Common causes of Over Temperature Error

  1. 01

    Empty or dry cookware on active burner

    Wiring / connection

    Running an induction burner with an empty pan or a pot that has boiled dry is the most common trigger. Without liquid or food absorbing the heat, surface temperatures spike rapidly past the 250°C limit.

  2. 02

    Faulty or degraded top sensor

    Part replacement

    A top sensor thermistor that has drifted out of its correct resistance range, or has failed partially, can send inaccurate high-temperature readings to the control board even when actual surface temperatures are normal. Testing the sensor resistance at a known ambient temperature will reveal whether it is out of spec.

  3. 03

    Loose or damaged top sensor wire connection

    Wiring / connection

    A wire harness connector that has backed out, corroded, or suffered heat damage at the top sensor port can cause intermittent or incorrect temperature readings. Inspecting and reseating the connector is a required diagnostic step before replacing the sensor itself.

  4. 04

    Inadequate cookware contact or improper pan size

    Wiring / connection

    Cookware that is significantly smaller than the burner zone, warped on the bottom, or not induction-compatible can cause uneven energy coupling, leading to localized hot spots on the glass surface that push the sensor reading above the safe limit.

  5. 05

    Main control board fault

    Part replacement

    If the top sensor and its wiring both test within normal parameters and the error recurs under proper cooking conditions, the main control board may be misreading or misinterpreting the sensor signal. Board replacement is a last-resort diagnosis after all sensor-side causes have been ruled out.

Frequently asked questions about Over Temperature Error

What does Over Temperature Error mean on a Samsung range?
It means the top sensor beneath the ceramic glass detected a surface temperature exceeding approximately 250°C, which is beyond the safe operating limit for the induction cooktop. The range shuts the affected burner down automatically to protect the glass surface and internal components. This is most commonly triggered by running a burner with empty cookware, but a faulty sensor or loose wiring connection can also be responsible.
Can I fix the Over Temperature Error myself?
In many cases, yes. If the error was caused by empty cookware, simply allow the hob to cool completely and the unit may return to normal operation on its own. You should also inspect the top sensor wire harness for loose or corroded connections, which is a straightforward check that does not require advanced tools. If the error persists after the unit has cooled and the wiring checks out, measuring the sensor resistance will determine whether the thermistor needs replacement, which is a moderate-difficulty repair.
Is it safe to keep using my Samsung range after this error appears?
You should not continue cooking until the cooktop has fully cooled and you have identified the cause of the error. If empty cookware was the cause, the unit is generally safe to use again once cool, provided you use cookware with food or liquid in it. If the error returns under normal cooking conditions, stop using the affected burner zone until the top sensor and its wiring have been inspected and tested, as a malfunctioning sensor means the protective shutdown may not operate reliably.
Will resetting the Samsung range clear the Over Temperature Error?
Allowing the cooktop to cool down fully will typically clear the error if the cause was a legitimate over-temperature event such as empty cookware. Cutting power to the unit at the breaker for a few minutes can also reset the control board. However, if the underlying cause is a faulty sensor or damaged wiring, the error will return during subsequent use and a reset alone will not resolve the problem.
How much does it cost to repair the Over Temperature Error on a Samsung range?
If the fix is simply reseating a loose wire connector, there may be no parts cost at all, only your time or a basic service call fee. Replacing the top sensor thermistor typically involves a parts cost in the range of $20 to $80 depending on the specific model, plus labor if you hire a technician. If the main control board is at fault, board replacement costs generally range from $150 to $400 or more for parts alone, making professional diagnosis worthwhile before committing to that repair.
