Hi all, Hope you can help. I have a Master TC-20 a few years old but hardly used. It's been in storage, went to use it the other night... Everything was fine then all of a sudden the motor stops and of course no air. The power light is on, but nothing. I let it sit for a couple days just plugged it in and tried it again... and of course nothing. It seems to have power but nothing else. Do you have any ideas? Thanks!
