Could be a timer issue - they don't make those anymore. An electrical multimeter can help you see what is happening.

Hi, I've seen this a few times. The knob that sets the amount of time is held on with an O-ring. It's most likely loose. Those old clocks are impossible to set to an exact amount of time to run. You need to actually time it. The zone in question maybe set to run 10 minutes but because of the loose O-ring it thinks it's set to 0. Try adjusting the dial. If it's set for 10 minutes put it on 20 and see what happens. Those O-rings are fairly easy to replace if need be.

Good luck!

I believe your neighbor is wrong. It's just about impossible for this to be a valve issue. The controller only provides power to the solenoids of the valves. If the valve is "broken", the controller wouldn't know it, it would still try to run the station. Since you've already mentioned in manual mode it skips the station in question, so that pretty much will eliminate it being a valve issue.



MrFixit seems to be heading you down the right path of where to look.

Worst case, you might have to just replace the controller, but is you record exactly which wire goes where on the current controller, that should be a fairly simple DIY job if need be.
