Common symptoms this part fixes

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

Pump or heater circuit not responding

Repeated blown fuse on same circuit

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

Before you buy — quick checklist

Confirm the blown fuse reads 30A — check the fuse body or your spa's wiring diagram before ordering
Verify your control system uses the MDA fuse format — MDA fuses are glass-body, slow-blow type; do not substitute with fast-blow (AGC) fuses
Identify why the fuse blew before replacing — a fuse that blows repeatedly indicates an underlying fault (short circuit, failed pump, or shorted heater element) that must be resolved first
Check your spa's fuse block or fuse holder for heat damage or corrosion before installing a new fuse
Have your spa's wiring diagram on hand to locate the correct fuse position in the panel

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