I have a pressurized CO2 system which has been running for a month. I have a solenoid which is attached to a timer and is set to switch on and off with the lights. Yesterday it switched off normally but today it didn't switch on. I plugged in the solenoid directly to the electricity skipping the timer to make sure the timer wasn't the problem but it still didn't switch on. I'm assuming there is a problem with the solenoid. I emailed the company where I bought if from. In the mean time is there anything I can try doing?
