What Does Error EE5 Mean?

The Sharp microwave combi oven error EE5 indicates an under-voltage condition, meaning the supply voltage is too low for proper operation. This error typically occurs immediately or shortly after power on, leading to the microwave refusing to start or stopping unexpectedly. Unusual sounds may accompany this error, signaling a malfunction in the heating element due to inadequate power supply.

Common Symptoms:

  • Error EE5 displayed on control panel
  • Microwave refuses to start or stops operation
  • Occurs immediately or shortly after power on

Possible Causes

  • Supply mains voltage below allowable threshold (medium)

How to Fix Error EE5

DIY Fix Check and stabilize mains supply voltage

  1. Unplug the appliance and wait a few minutes.
  2. Try connecting the microwave to a different outlet on a known stable circuit.
  3. Avoid using extension cords or power strips that may cause voltage drop.

Technician Only Evaluate power input and perform service if needed

  1. Measure incoming mains voltage with a reliable multimeter at the appliance outlet.
  2. Verify that internal voltage selector (if present) and supply configuration match local mains standards.
  3. Inspect internal power supply circuitry for damage caused by sustained under‑voltage.
  4. Replace any damaged components (control board, transformers) if verified faulty.

Parts needed: Multimeter (for diagnosis), Control board, Voltage selector or power supply components

🛑 When to Call a Pro:
  • If error persists after verifying adequate mains voltage
  • If the appliance exhibits electrical smells, smoke, or other hazards
