I've had a Jet Air Filtration unit (AFS 1000B) system for years and it's worked perfectly. Recently I took out the filters for cleaning. When I put them back the unit would not start. All of the lights came on (ALL of them, including lights that should not be on at the same time) but the unit does not start.

Does anyone have any idea where to start in diagnosing the problem?

    When you put the filters in place they may push a tab or button which must be depressed for the unit to operate. This would be to insure that the unit is not operated without a filter in place. Remove the filters again and see if there is an interlock like this which is somehow not depressed the way the filters are currently in place. It might be that the order of the filters is important and the interlock is to insure that the filters are in the correct order. There could be two interlocks and one must be depressed and the other extended. Aug 13, 2019 at 15:57

    Did you try contacting Jet directly?

My AFS1000B air filter system started acting up after several years of use. In my shop I have it plugged into the same circuit where I have several fluorescent light fixtures connected. Over the years I have replaced several of the fluorescent fixtures with LED fixtures. My remote stopped cycling through the time selections and the fan would not run for very long before it would automatically shut off. I fixed this issue by removing the remaining two fluorescent light fixtures and replaced them with LED. So obviously it had something to do with Fluorescent fixtures, or perhaps my fluorescent fixtures got too old but anyway, it is working fine now, so for whatever it’s worth it might be useful to disconnect the fluorescent fixtures and see if the fan will operate properly
