Sounds like a problem with the solenoid. If you have 24 volts to the solenoid then you need to replace the solenoid. It could also be a bad connection so if you don't have 24 volts or the voltage fluctuates then you need to go back to the controller and check the voltage there. If it's constant you need to rack down the bad connection.
Do you have more questions?
