Possible Causes

Weak or failing low-voltage regulator on control board, Loose neutral or live connection, Electrical noise from other appliances on same circuit, Failing internal capacitor on PCB

How to Fix / Troubleshooting

Safety: Always unplug before opening the cabinet. If you suspect house wiring issues, contact a licensed electrician.

Steps:

  • 1. Dedicated outlet: Plug the microwave into a dedicated wall outlet without sharing with high-load appliances (dishwasher, oven, etc.).
  • 2. Check plug fit: Ensure the plug fits tightly in the outlet; loose contacts can cause voltage drops.
  • 3. Power reset: Unplug for 10 minutes, then reconnect and set the clock. Monitor for reoccurrence of E13.
  • 4. Surge protection: Consider using a quality surge protector rated for microwaves to stabilize minor fluctuations.

Resolution: If E13 continues, the main control PCB likely has failing power supply components and should be replaced with the correct IKEA-compatible board.
