New October last year. Used yesterday and worked but today can’t get red light to turn off. Use to fill my 2l tank as needed which isn’t often given my weather. Is there a reset button? Bad switch? Doesn’t look difficult to take the cover off but haven’t yet. Bought on amazon and sent a note to the seller but don’t know if/when I’ll hear back from them. Suggestions? Who do you contact when you have a problem with a GX compressor? Thanks.
