Sharp Microwave Error Code EE14

EE14 indicates that the control system has detected fan motor 1, which cools the magnetron (MG1), is locked or not running. The microwave monitors this fan continuously during operation and triggers EE14 when it determines the fan has stopped or failed to start. This is a protective fault designed to prevent thermal damage to the magnetron and surrounding components.

Unplugging the microwave and restoring power may temporarily clear the fault display, but EE14 will return as soon as the control board detects the fan is still not operating correctly. A reset does not fix the underlying mechanical or electrical problem causing the fan to fail. The fan motor and its associated wiring and components must be inspected and repaired before the error is truly resolved.

Repair costs vary depending on the failed component. A replacement fan motor typically costs between $20 and $60 for the part, while a new control board can range from $80 to $200 or more depending on the model. Adding professional labor, total repair costs generally fall between $100 and $300. If the microwave is older, it may be worth comparing the repair estimate against the cost of a replacement unit before proceeding.

No, it is not safe to continue operating the microwave with an EE14 fault active. The cooling fan is essential for removing heat from the magnetron during use. Running the unit without a functioning fan can cause the magnetron to overheat, potentially damaging it permanently and creating a fire risk. Keep the microwave unplugged until the fan issue is resolved.

Start by unplugging the unit and checking whether the fan blade rotates freely by hand, as a seized motor or obstruction is the most common cause. If the blade is free but the motor still does not run, use a multimeter to check for voltage at the motor terminals and to test the motor winding continuity. Depending on the findings, the repair may involve cleaning debris from the fan housing, replacing the fan motor, repairing the wiring harness, or replacing the control board if a relay has failed.
