How to Fix / Troubleshooting

Safety: Always unplug the unit before opening the control housing. Only qualified persons should test live voltage.

  • Check outlet: Test the wall socket with another appliance to confirm power is present.
  • Inspect power cord: Look for damage or loose plug. Replace if necessary.
  • Check transformer output: With a multimeter, measure the transformer secondary voltage and compare to its rating. Replace the Tapworks transformer if no output.
  • Inspect internal fuse: Some Tapworks boards have a small fuse. Replace only with the same type and rating if blown.
  • If power reaches the board but display remains dead: Replace the control PCB or display module as appropriate.
