Severin Keypad / Membrane Failure

Microwave display works, but pressing buttons does nothing or only some buttons respond.

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

Worn membrane contacts, Cracked keypad ribbon cable, Moisture ingress, Faulty control PCB keypad input

Safety first: Unplug the microwave before removing the control panel.

Step 1 – Try reset: Disconnect power for 5–10 minutes, then reconnect and test the keypad.
Step 2 – Clean surface: Wipe the keypad with a dry cloth. Avoid excessive moisture.
Step 3 – Inspect ribbon cable: Remove the control panel and check the flat cable from the keypad to the PCB for cracks or corrosion. Reseat the connector.
Step 4 – Replace keypad: If specific keys consistently fail, replace the membrane keypad or entire control panel assembly.
