Samsung Microwave Error Code F-10
Thermistor shorted — over-temperature protection
The most common cause of the F-10 error on a Samsung microwave is thermistor shorted internally (~55% of cases); start with: let the microwave cool.
What Does Error Code F-10 Mean on a Samsung Microwave?
Thermistor shorted — over-temperature protection.
The cavity thermistor is reading as a short, so the microwave can't trust temperature feedback and shuts down to prevent undetected overheating. A failed thermistor is the most common cause, though blocked vents can overheat the cavity and damage the sensor first.
What Causes Error Code F-10?
Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:
- 1 Thermistor shorted internally 55% of cases
- 2 Overheating from blocked vents or poor clearance 30% of cases
- 3 Pinched/shorted thermistor wiring 10% of cases
- 4 Control board sensor input failure 5% of cases
