Sharp Microwave Error Code EE4: How to Fix It

Q: Can I still use my Sharp microwave with EE4 error?

Yes, you can typically still use manual power settings and time controls. However, automatic sensor cooking programs like popcorn, reheat, or defrost may not work properly until the humidity sensor is repaired.

Q: What causes Sharp microwave EE4 error code?

EE4 errors are usually caused by a faulty humidity sensor, moisture buildup affecting sensor readings, loose electrical connections, or damage to the sensor's wiring harness.

Q: How much does it cost to fix Sharp microwave EE4 error?

If the issue is resolved by cleaning or reconnecting wires, the repair is free. If the humidity sensor needs replacement, professional repair typically costs $100-200 including parts and labor.

Q: Is Sharp microwave EE4 error serious?

No, EE4 is a low-severity error that doesn't affect basic microwave heating functions. It only impacts automatic sensor cooking programs, so the microwave remains safe to use manually.

Q: Where is the humidity sensor located in Sharp microwaves?

The humidity sensor is typically mounted inside the microwave cavity near the ceiling or behind the waveguide cover. It's usually a small cylindrical component connected to the control board via a wire harness.

Abstract

Sharp microwave error code EE4 indicates a humidity sensor malfunction. This sensor helps the microwave detect moisture levels for automatic cooking programs, but when it fails, you'll see the EE4 error display.
