Sharp Microwave Error Code EE19

EE19 on a Sharp microwave means the unit has detected no food or load inside the oven cavity during operation. This is typically flagged by the sensor cooking system when the humidity or load-detection circuit fails to register a proper signal. It can result from an empty cavity, a dirty sensor, or a faulty sensor or control board.

You should not continue operating the microwave while this error is active. Running a microwave with no detectable load can cause the magnetron to sustain damage from reflected energy over time. Resolve the underlying cause before resuming normal use.

Repair costs vary depending on the cause. Cleaning the sensor involves no parts cost. Replacing a humidity sensor typically costs between $20 and $60 for the part, plus labor if a technician is needed. Control board replacement is more expensive, generally ranging from $80 to $200 or more for the part alone. In some cases, the total repair cost may approach the price of a comparable replacement microwave, so it is worth comparing costs before proceeding.

In many cases, yes. Start by unplugging the microwave, then thoroughly cleaning the interior walls and the humidity sensor area with a damp cloth to remove grease or food residue. If the error persists after cleaning and ensuring food is placed inside before cooking, the repair may require replacing the humidity sensor or having the control board inspected, which involves working near high-voltage components and should be handled by a qualified technician.

A reset, typically performed by unplugging the unit for one to two minutes and restoring power, may temporarily clear the error code. However, if the root cause such as a dirty sensor, faulty sensor, or wiring issue is not addressed, the EE19 code is likely to return during the next cooking cycle.
