Possible Causes

Failed low-voltage power supply on main PCB, Blown internal line fuse, Shorted component on control board, Loose mains connector

How to Fix / Troubleshooting

Safety: Unplug the microwave before removing any covers. Internal fuses are not user-serviceable in some regions; check local regulations.

Steps:

  • 1. Check the outlet: Verify that the wall outlet has power by testing with another appliance.
  • 2. Inspect the power cord: Look for cuts, burns, or kinks. Do not use the microwave if the cord is damaged.
  • 3. Internal fuse check (DIYers): Remove the outer cabinet and locate the line fuse near the power entry. Test for continuity. If blown, investigate for shorts before replacing with the exact same rating.
  • 4. Control board inspection: Look for burnt components or cracked solder joints on the main PCB.

Resolution: Replace the main control PCB or line fuse (after identifying and correcting the root cause) with the correct IKEA-compatible parts.
