Clatronic Power Supply Instability to Control Board

Electronic display flickers or dims when oven heats.

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

Weak internal power supply on control PCB, loose neutral connection, overheating of control area, failing capacitors

Safety first: Disconnect mains power before accessing the control board.

Check connections: Inspect the terminal block and neutral connections for looseness or discoloration. Tighten as needed.
Inspect control board: Look for bulging electrolytic capacitors or heat-damaged components in the low-voltage section.
Improve cooling: Ensure the cooling fan works and vents are not blocked, as overheating can worsen flicker.
Replace board: If components are visibly failing or flicker persists, replace the electronic control board.
