Hoover Single Key Failure on Membrane Keypad

Microwave display works, but the START button does nothing; other buttons (clock, power level) respond normally.

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 START key contact in membrane, Contamination under keypad overlay, Partial break in keypad ribbon cable, Control PCB key input fault

Safety first: Unplug the microwave before panel removal.

User-level checks:

Try using an alternative start method if available (e.g., quick-start or +30s key) to confirm only the START key is affected.
Clean the keypad surface and ensure it is dry.

Next steps:

A failed START key usually requires replacement of the membrane keypad or entire control panel fascia.
Contact a technician or Hoover service for the correct replacement part.
