I’m having a problem with my gun. I coated a wheel and then put it in the oven and cleaned the gun out for a new color went to spray another part and the powder wouldn’t stick. so I figured the I had forgotten to reconnect my ground I checked it and it was good, then moved it to the actual part and had the same problem. I then noticed that the red light on the top isn’t lighting like it should. so I’m wondering if anyone has had this problem before. if you have any info for me it would me greatly appreciated.
