Hello, I came home the other day to my spa jet pump running. Hit the air switch and nothing.
The pump turns on and off at the breaker like it's latching.
e.g. on-off-on=pump off, on-off-on=pump on, on-off-on=pump off, etc.

Did some online research and the air sensor 860010-0 is available for around 20-25 bucks. The entire AS-2 box is around 130.00.
After opening the box, I see there is also a solenoid inside.
Any suggestions on how to test to see which is faulty?
I'm thinking because the of the latching behavior of the switch when cycling the breaker, that the solenoid is good and it is the air sensor.
Thoughts?
Thanks in advance.
