I know everyone is busy prepping for this evening but I'm hoping someone has some insight as to why my fog machines aren't working. Pulled them both out of storage and when I press the fog button, they click (relay works) and hum (not vibrate like usual) but nothing happens. I disassembled the pumps on both, made sure everything was good there and was rewarded briefly by a burst of fog on my Chauvet 1301. Thinking the problem was solved I put the cover back on. Moved it out front and no fog. I took the line, hooked up a syringe full of fog fluid and squeezed, out came fog so it doesn't appear to be clogged and the heating element is working. Has my coil mysteriously gone bad on both machines since last year on both machines? One is a Chauvet 1301 and the other is a Chauvet 1100...the 1301 only lasted one season. Can anyone think of anything else to try? Thanks in advance!
