Sharp Microwave Error Code EE15

EE15 indicates an antenna rotation error in the MG1 system of your Sharp microwave. The control unit has detected that the internal rotating antenna is not moving as expected. This fault involves the antenna motor, the rotation sensor, the control unit, and the wiring connecting them. The microwave will typically stop operating until the fault is diagnosed and resolved.

You should not continue using the microwave while EE15 is active. The rotating antenna is a key part of how the microwave distributes energy evenly, and operating with a faulty antenna system can result in uneven heating and potential stress on other components. The microwave will typically prevent normal operation when this code is present as a protective measure.

Repair costs vary depending on which component has failed. Replacing an antenna motor or rotation sensor typically falls in the range of $50 to $150 for parts, plus labor if a technician is hired. Control unit replacements are more expensive, often ranging from $100 to $250 or more for the part alone. If the issue is only a loose wire or obstruction, there may be no parts cost at all. For older or lower-cost microwaves, comparing repair costs to replacement costs is worthwhile.

Some causes of EE15, such as a mechanical obstruction blocking the antenna or a loose wiring connector, can be addressed without specialized tools. However, working inside a microwave involves high-voltage capacitors that can hold a lethal charge even when unplugged, so internal repairs should only be attempted by technicians or experienced DIYers who know how to safely discharge the capacitor. Replacing the antenna motor or sensor is possible with the right part, but the control unit replacement is more complex.

Unplugging the microwave for a few minutes may temporarily clear the error code, but EE15 will return if the underlying cause is not repaired. If the antenna motor, sensor, or wiring has actually failed, the fault will reappear as soon as the control unit attempts to verify antenna rotation during the next cooking cycle. A reset is useful for confirming whether the fault is intermittent, but it is not a fix.
