How to Fix Error Code EE 1

  1. Safety first - disconnect power

    Microwave ovens contain high-voltage capacitors that can retain dangerous electrical charges even when unplugged. Never attempt repairs while the unit is connected to power.
  2. Remove the outer cabinet

    Be extremely careful around the magnetron and high-voltage capacitor. Do not touch any internal components with bare hands.
  3. Locate the cavity sensor

  4. Test the sensor with a multimeter

  5. Check wire connections

  6. Replace the faulty cavity sensor

    Use only genuine Sharp replacement parts or equivalent sensors with the same specifications to avoid further damage.
  7. Reassemble and test

When to Call a Professional

If you're uncomfortable working with electrical appliances, cannot locate the cavity sensor, or the error persists after replacing the sensor, contact a qualified appliance repair technician. High-voltage components in microwaves can be dangerous and may require professional diagnosis of the control board or other internal components.

Frequently Asked Questions

What causes Sharp microwave error code EE 1?
Error code EE 1 is caused by a faulty cavity sensor (thermistor) that has developed an open circuit. This can happen due to age, heat damage, moisture exposure, or manufacturing defects.
Can I still use my Sharp microwave with EE 1 error?
No, you should not use your microwave when it displays error code EE 1. The cavity sensor is a critical safety component that prevents overheating, and using the microwave without a functioning sensor can damage internal components or create safety hazards.
How much does it cost to fix Sharp microwave EE 1 error?
A replacement cavity sensor typically costs $15-40. Professional repair services may charge $100-200 including labor. The repair is often cost-effective compared to buying a new microwave.
How do I prevent Sharp microwave EE 1 error in the future?
Keep your microwave clean, avoid excessive moisture buildup, don't slam the door, and have it serviced periodically. Most cavity sensor failures are due to normal wear and age rather than preventable causes.
Will resetting my Sharp microwave fix EE 1 error?
No, unplugging and resetting will not fix EE 1 error because it indicates a hardware failure of the cavity sensor. The faulty sensor must be replaced to resolve this error code.
