Sharp Range Error Code EE 6

EE 6 means the control board detected an open circuit in the oven thermistor circuit when the oven attempted to start. The thermistor is the temperature sensor inside the oven cavity, and an open circuit means no valid resistance signal is reaching the control board. The oven shuts down to prevent uncontrolled heating without temperature monitoring. The fault is detected at startup, so the error will appear each time you try to use the oven until the problem is resolved.

You should not attempt to use the oven while EE 6 is active. The error indicates the oven has no functioning temperature sensor, which means the control board cannot regulate or limit the heat inside the cavity. Operating the oven without a working thermistor creates a risk of overheating. The stovetop burners are a separate system and are generally unaffected, but the oven should remain out of service until repaired.

If the repair requires only a new oven thermistor, parts typically cost in the range of $15 to $60 depending on the specific model, and the repair is relatively simple if done independently. If a professional technician is needed, expect a total repair cost in the range of $100 to $250 including labor and parts. A faulty control board is the most expensive scenario, with parts alone potentially ranging from $150 to $400 or more, which may factor into a repair versus replace decision.

A knowledgeable DIYer can diagnose and fix this error in many cases. Start by unplugging the range and locating the oven thermistor, then use a multimeter to test the thermistor for continuity and check the wiring harness for breaks or loose connectors. If the thermistor reads open on a multimeter, replacing it is a straightforward repair. If the wiring and thermistor are intact but the error persists, the control board may need professional evaluation.

A power reset, such as unplugging the range for a few minutes, may temporarily clear the display, but the EE 6 code will return the next time you attempt to start the oven if the underlying problem has not been fixed. The fault is detected fresh at each startup, so resetting without repairing the thermistor circuit will not resolve the issue.
