We guarantee precise fitment and back every part with our comprehensive 1-year warranty for complete peace of mind.

Common symptoms this part fixes

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

Spa heater or pump fails to energize when called
Contactor chattering or buzzing under load
Spa equipment cuts out unexpectedly under load
Burned or pitted contactor contacts causing intermittent operation
No 240V output at load terminals despite correct input voltage
Spa controller sends signal but equipment never activates

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

Before you buy — quick checklist

Confirm your existing contactor is rated 50A — do not substitute a lower amp-rated contactor
Verify coil voltage is 115VAC — using a contactor with a mismatched coil voltage will result in failure to pull in or coil burnout
Check that your application requires DPST (double pole, single throw) — DPDT contactors are not interchangeable
Inspect your control board output signal to confirm it delivers the correct coil voltage before installing the new contactor
Confirm physical dimensions and terminal layout match your existing contactor and enclosure mounting points

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