Miele Solid-State Relay / Triac Misfiring

Oven interior light and fan work, but elements cycle on and off very rapidly, causing poor heating.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Defective triac or SSR on control board, Electrical noise on control signals, Poor neutral connection, Control firmware issue

Safety first: Turn off power and remove the control panel to access the electronics.

Visual inspection: Look for burnt or cracked solid-state relays or triacs on the control board.
Check connections: Ensure all control and power connectors to the board are secure.
Board replacement: If misfiring persists and no external cause is found, replace the main control module.

Because this involves live switching devices, replacement should be done by a qualified technician.
