Timer nor air switch will shut off my pump. It's an Intermatic 4 cycle timer for an inground spa with a single speed pump. The air switch and complete timer controller have been 4e0oac3e. Same issue. The tubing checks out as well. Mystery.

Can't be much of a mystery as something has to be letting the power through to the pump.. :mrgreen:

My guess would be whatever was replaced first was wired wrong providing constant power to pump. Just a guess of course, but based on the systems I have had to fix after the first tech screwed it up.. :)

Let's see some pics of the wiring, the timer, etc

I assume the pump shuts off when the breaker is off.. Does the pump run off of 120 volts or 240 volts??
