Common symptoms this part fixes

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

  • Spa blower or jet pump won't respond to air button press
  • Air button activates but component stays off
  • Component cycles on and off erratically when air button is pressed
  • Air button press produces no switching action
  • Spa function stuck in on or off position regardless of button input

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

Before you buy — quick checklist

  • Confirm this is a vacuum-actuated switch — PresAir makes both pressure and vacuum variants; verify your system uses a vacuum signal
  • Check your existing switch's amperage rating — this unit is rated 25A SPDT; ensure that matches your load
  • Verify tubing barb size on your existing switch before ordering to confirm the air line will mate correctly
  • Confirm SPDT configuration is correct for your application — some circuits require SPST or DPDT
  • Test your air button tubing for cracks or blockages before replacing the switch; a leaking tube causes identical symptoms and is a common misdiagnosis

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