Microwave beeps and shows E05; cooking stops unexpectedly

SAFETY: Unplug the microwave before opening the cabinet. Avoid the high-voltage section.

E05 indicates the control cannot read the cavity temperature correctly.

• Step 1 – Reset and environment:
  • Allow the microwave to cool for 20–30 minutes if it has been used heavily.
  • Unplug for 5 minutes, then reconnect and test.
• Step 2 – Locate the thermistor (for competent DIYers):
  • Remove the outer cabinet.
  • Look for a small sensor (often in a metal or plastic housing) attached to the top or side of the cooking cavity with two wires leading to the control board.
• Step 3 – Inspect connections:
  • Check that the thermistor plug is firmly seated on the control PCB.
  • Inspect the wire insulation for cuts or burns.
• Step 4 – Test/replace (for technicians):
  • Measure the thermistor resistance at room temperature and compare with SilverCrest service data.
  • Replace the thermistor if readings are out of specification or intermittent.

If the sensor and wiring are good, the control PCB may be defective and require professional replacement.
