My 27' Fever 496 ci silent choice activates just fine, but after a minute, or so, it goes off. Anyone know if this is fixable? Thanks!

Look at the air pump and you will see a fitting on the side of the pump. This is an over pressure relief valve. Take the valve off the pump and you will see it has a nut and spring on the inside. The valve may have some trash on the seat or, like in my case the spring just got weak and I tightend the nut to put more pressure on the spring and

fixed my problem

When you look at the pump there is a 4 way block. one port is screwed to the pump and the other two have hoses hooked to them and the brass fitting with nothing ho

hooked to it is the valve.

Some systems are air actuated.
Some systems have electric solenoids.

The solenoid controlled systems can and do have solenoids that fail over time.

Thanks...will approach as you two kind folks advised.
