Sharp Microwave Error Code EE6

EE6 indicates that oven thermistor (1) has been detected as open, meaning the temperature sensor circuit has lost continuity and is not sending a valid signal to the control board. The microwave uses this thermistor to monitor internal cavity temperature, and when the reading is absent, the unit shuts down as a safety precaution. The thermistor itself, its wiring, or a connector in the circuit is the likely source of the fault.

No, the microwave should not be used while EE6 is active. The control board has disabled operation because it cannot monitor cavity temperature, which means there is no reliable safeguard against overheating during a cooking cycle. Continue using the unit only after the fault has been diagnosed and repaired.

If the repair is limited to reseating a connector or addressing a loose wiring issue, out-of-pocket costs may be minimal. Thermistor replacement parts typically fall in the range of $15 to $50 depending on the specific model. If professional labor is needed, total repair costs including parts and service time generally range from $80 to $180, though costs vary by region and service provider.

A knowledgeable DIYer can begin by inspecting and reseating connectors in the thermistor circuit, which requires no parts and may resolve the code if a loose connection is the cause. Replacing the thermistor itself is also a straightforward repair if you are comfortable working inside the appliance cabinet. However, microwave interiors contain a high-voltage capacitor that can hold a dangerous charge even when unplugged, so proper discharge procedures must be followed before touching any internal components.

Unplugging the microwave for a minute and restoring power may temporarily clear the display, but the EE6 code will return as soon as the control board performs its next diagnostic check if the underlying fault has not been corrected. A reset does not repair a failed thermistor, broken wire, or faulty connector. The root cause must be addressed for the error to stay clear.
