About this fuse

This genuine Gecko Alliance 0.5 amp glass fuse (430AC0222) provides essential electrical protection for spa control systems and heating circuits. Measuring 1-1/4" x 1/4" with MDL time-delay characteristics, this replacement fuse safeguards your spa's sensitive electronics from power surges and overcurrent conditions that could damage expensive components.

As an OEM Gecko part, you get exact fit guaranteed and reliable performance that matches your spa's original specifications. We ship same-day from our Canadian warehouse and back every part with a full 1-year warranty for complete peace of mind. Always replace blown fuses with the identical amperage rating—using a higher or lower amp fuse can damage your spa's electrical system or create safety hazards.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Spa control board has no power
  • Circuit board repeatedly losing power or resetting
  • Spa displays fault code related to power supply
  • Protection fuse on Gecko control board is visibly blown or open

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm the blown fuse reads 0.5A — amperage is printed on the fuse end cap or body
  • Verify the physical fuse dimensions are 1-1/4" x 1/4" (standard MDL/AGC glass tube size)
  • Confirm your Gecko board calls for an MDL time-delay (slow-blow) type, not a fast-blow AGC fuse — they are not interchangeable
  • Do not upsize the replacement fuse amperage to "fix" repeated blowing — that indicates an underlying fault that needs diagnosis first
  • Inspect the fuse holder clips for corrosion or heat damage before installing the new fuse

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
