Irrigation will not turn on when set to auto

I have an Intermatic model R8806P101C It operates and turns on each manually without a problem. Timer seems to be working ok but when it is set to auto it will not turn on. Has anyone experienced this and if so what is the cure?

It could be as simple as a bad toggle switch. You will have to diagnose this yourself with the aid of a multimeter. The controller is dead simple, so just find the bad part(s)

However, you might best be served by looking for a replacement. These show up on eBay a lot, as systems get modernized. Note that there are many variations on this clock, so other model numbers can be a match. Read the descriptions carefully.
