7091 Controller not switching

[catman78]

Hi,

Took out pump for cleaning. When I reassembled and plugged controller back in it does not switch channels. Stays on # 2.
Tried unplugging and restarting several times with no luck.

Any suggestions ?

Thanks
Mark

Usually the cause will be that the pulse knob is turned all the way clockwise to off or the photocell is in darkness or salt creep has shorted the photocell socket.
