Samsung Range Error Code E-24

The E-24 code on a Samsung range indicates an oven overheating error where the oven temperature fails to reach 650°F (343°C) during any standard cooking function. The control board monitors oven temperature through a resistance-based temperature sensor, and this code appears when that sensor circuit reports a value outside normal parameters. It does not trigger during the self-clean cycle. The most common cause is a failed or out-of-spec oven temperature sensor.

It is not recommended to continue using the oven while the E-24 code is active. The error indicates the control board cannot accurately monitor oven temperature, which means the oven may not heat correctly or could potentially overheat without proper regulation. The cooktop burners may still function, but the oven should not be used until the fault is diagnosed and repaired.

Disconnecting power briefly may clear the error code from the display temporarily, but if the underlying fault in the sensor or wiring still exists, the E-24 code will return once the oven attempts to heat again. A reset is useful as a first step to confirm the fault is persistent, but it does not repair the cause. A proper fix requires testing and replacing the faulty component.

A knowledgeable DIYer can perform the initial diagnostic step by disconnecting power, removing the rear cover, and measuring resistance at the oven temperature sensor's harness connectors. If the resistance is out of spec, replacing the sensor is a relatively straightforward repair involving removing the sensor from inside the oven cavity and plugging in the new component. However, if the wiring harness or control board is involved, professional service is recommended to avoid further damage.

Repair costs depend on the faulty component. A replacement oven temperature sensor is typically the least expensive fix, with parts generally ranging from $20 to $60 and professional labor adding $75 to $150 depending on your area. If the main control board needs replacement, parts alone can range from $100 to $300 or more, making total repair costs significantly higher. Getting a diagnostic estimate before committing to a board replacement is advisable.
