The TE error on your Samsung Microwave means there’s a malfunction with the temperature sensor or related circuitry. This error prevents the microwave from operating safely and requires immediate attention to restore proper function.

Error code TE
Meaning Temperature sensor error or thermistor malfunction
Severity High — Microwave will not operate until resolved
Time to fix 15–45 minutes
Tools needed Multimeter, screwdriver set, needle-nose pliers

What the TE error means

The TE error code indicates that your Samsung microwave has detected a problem with the temperature sensor (thermistor) or its associated wiring. This sensor monitors internal temperatures to prevent overheating and ensure safe operation. When the control board cannot receive proper temperature readings, it triggers the TE error and shuts down the microwave to protect internal components from potential damage.

Common causes

  • Faulty or damaged thermistor sensor that provides incorrect temperature readings
  • Loose, corroded, or disconnected wiring harness between the thermistor and control board
  • Defective main control board unable to process sensor signals correctly
  • Moisture or grease buildup on sensor connections causing intermittent failures
  • Physical damage to the sensor from overheating or mechanical impact
  • Short circuit in the thermistor wiring harness

How to fix the TE error

  1. Power cycle the microwave — Unplug the microwave from the electrical outlet for 2–3 minutes to reset the control board. Plug it back in and test if the error clears. This resolves temporary electronic glitches.
  2. Inspect thermistor connections — Unplug the microwave and remove the outer cabinet panels using a screwdriver. Locate the thermistor (usually mounted near the magnetron or vent) and check all wire connections. Clean any corrosion and ensure connectors are firmly attached.
  3. Test the thermistor with a multimeter — Disconnect the thermistor wiring harness and set your multimeter to resistance (ohms). At room temperature (68–72°F), the thermistor should read approximately 50,000–70,000 ohms. If the reading is infinite (open circuit) or zero (short circuit), replace the thermistor.
  4. Check wiring harness continuity — Use the multimeter to test continuity along the wiring from the thermistor to the control board. Look for broken wires, damaged insulation, or signs of burning. Replace any damaged wiring sections or the entire harness if necessary.
  5. Replace the thermistor — If testing confirms the sensor is faulty, order a replacement part specific to your Samsung microwave model number. Disconnect the old thermistor, install the new one in the same location, and reconnect the wiring harness securely.
  6. Replace the control board if necessary — If the thermistor and wiring test normally but the error persists, the main control board may be defective. This requires professional diagnosis or replacement with an OEM Samsung control board matched to your model.

FAQ

Can I use my Samsung microwave with the TE error code displayed?
No, the microwave will not operate when the TE error is active. This is a safety feature designed to prevent damage from overheating or component failure. The error must be resolved before normal operation can resume.

How much does it cost to fix a TE error on a Samsung microwave?
A replacement thermistor costs $15–$40, and you can install it yourself in 30–45 minutes. If you need professional repair service, expect to pay $150–$250 including parts and labor. Control board replacement runs $200–$350 if that component is faulty.

Will resetting my Samsung microwave clear the TE error permanently?
A power reset may temporarily clear the error if it was caused by an electronic glitch, but if the thermistor or wiring is actually faulty, the TE error will return during operation. Permanent resolution requires repairing or replacing the defective component causing the sensor malfunction.
