High pitch noise from sprinkler

When my sprinkler goes on in the morning I hear a high pitch noise and they actually don't go on.
I usually have it on auto and I tested the system by putting it on manual. When I did the noise came on and the sprinkler didn't work.
The sound is definitly coming from the unit which is above the ground where all the pipes meet and where the electrical connection is.
Any help is appreciated.

Thank you.
