Control display is blank but outlet has power

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

Failed Lindsay transformer, Blown internal fuse (if present), Loose low-voltage connector, Failed control board

Safety first: Unplug the transformer before opening the control head.

Check transformer: Test output voltage with a multimeter. Replace if no output.
Inspect fuse: Some Lindsay boards have a small fuse. Replace only with the same rating if blown.
Reseat connectors: Ensure the low-voltage plug is fully seated on the board.
Replace board: If power is present at the board but the display remains blank, replace the Lindsay control board.
