Hunter Pro C zones 4,5 & 6 stopped working


Today I tried to turn on my sprinkler system for the first time since the system was turned on and checked for the season back in May. I was using the manual override to spot-water my first few zones. Numbers 1, 2 & 3, 7, 8, 9 & 10 all work perfectly, however zones 4, 5 & 6 do not come on even though the digital display shows they are running. No one has touched any of the wiring or control panel since May. I haven't found any threads discussing this particular problem. Any suggestions?

The module might be bad for 4-5-6. Take out the back up battery and unplug the controller. Take out the module, swap it with the 7-8-9 module. Turn the power back on. Now see what's working and what's not.
If your Pro-C has a locking mechanism for the modules, make sure it's locked into place after replacing the modules. Of course you have to unlock it to get the modules out.

I suppose it's possible that 4-5-6 have their own common wire but wait and see what happens with swapping the modules.
Maybe move the number 7 wire to the number 6 slot and see if 7 still works.
