Sharp Microwave Error Code EE38

EE38 indicates a microwave sensor fault affecting Magnetron 1 and Magnetron 2 in your Sharp microwave. The control unit has detected that it cannot confirm proper microwave output from one or both magnetrons through the sensor circuit. The appliance stops operating to prevent unsafe conditions. Diagnosis involves checking the magnetrons, control unit, wiring, and the sensor itself.

No, you should not attempt to operate the microwave while the EE38 fault code is active. The code indicates the control unit cannot confirm proper microwave output, meaning the appliance may not be functioning safely or effectively. Continued use before the fault is resolved and cleared is not recommended.

Repair costs vary depending on which component has failed. Wiring repairs tend to be the least expensive option, generally in the range of $50 to $150 for labor. Replacing a microwave sensor or control board may cost between $100 and $250 or more including parts and labor. Magnetron replacement is typically the most expensive repair, often ranging from $150 to $350 or higher, and may make repair less economical depending on the age and model of the unit.

Some wiring and connector issues can be identified by a knowledgeable DIYer, but working inside a microwave carries serious safety risks due to high-voltage capacitors that can retain a lethal charge even when unplugged. Component replacement such as a magnetron or control board should be handled by a qualified appliance technician. At minimum, the capacitor must be safely discharged before any internal inspection.

A power reset by unplugging the unit for a few minutes may temporarily clear the code, but EE38 will typically return if the underlying fault in the magnetron, sensor, wiring, or control unit has not been repaired. Clearing the code without fixing the root cause does not make the appliance safe or functional for normal use.
