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?

  • Are there any error codes in the manual?

    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
  • I took a quick look last night and didn't see anything - I'll take a more thorough look tonight Aug 13, 2019 at 17:30
  • Did you try contacting Jet directly?
