AFS1000 Jet Air Filter doesn't work

[Wade Lippman]

It spun by hand easily enough. I put some oil into it, and it didn't change.

I tried spinning it by hand and then turning it on. It acted like a brake. Trying to spin it faster by hand while it was turning didn't help either.

Since it was cheap to try, I replace the capacitor and it didn't help. A new WEN is cheaper than replacing either the motor or circuit board (and I don't know which is bad...) so actually repairing it is probably not an option at this point.
I would think that I could wire around the circuit board and have it run on only high. How would I do that? The wiring is shown in:

Might not work, but I've got nothing to lose.

I have similar Jet and similar problem: mine only runs on high, no low or med speed; off-delay timers work fine; same output regardless of my inputs = on-board control panel and remote.

I did basic trouble-shooing to find the problem, and motor seems fine. So I'm convinced it is in the on-board electronic control module, tho' I see no obvious damage or magic smoke release. I could replace the baord ($?? - assuming its still available?), perhaps repair it if I can ID the failed surface mount 'chip', or live with it as-is.

I always ran it on high before, so at this point, as-is it is!

In your case, if you want / can live with just high, I'd probably look at wiring the motor direct to a wall switch. I can't open the link to the manual, so not sure the OEM motor will support this? Might mean a motor swap?

(Will try the link again later; can't access my hardcopy at the moment.)

ETA - the link site just let me in. Manual's schematic is useless to determine voltage, so far as I can see. I know its tough to access, but does your motor nameplate have wiring diagram? If so, can you post photo of it? (Too long since I looked at mine.)

Take a look at this...

Another dirt quick search shows 'black/blue/yellow' motor wires all tied to same 120VAC line source *IGNORE THIS* (for high speed); 'white' motor wire goes to source neutral; green motor wire to source ground.

**************
I do very little with fractional Hp motors and it shows. Other sources say connect only ONE of these blk/blu/ylw wires to source. Not sure what to tell you except consult with a HVAC guru.

I've got the same unit . Mine doesn't respond to the remote for speed changes , but will for on/off . It's 20 yrs. old , so I'm hanging on and hoping for the best .

I replaced a 2200mf capacitor on the circuit board and it works! Can you believe that, I fixed it!
If I had know more about electronics I would have noticed that the capacitor was puffed out at the back and saved an awful lot of time.
The soldering looks like a monkey did it. I am going to try to improve it a bit; sure hope I don't ruin anything.
Thanks all.
(I would have been happy to run it on high off a toggle switch, had it come to that.)

Nice going Wade. Go very easy with heat when soldering and be sure to clean off any flux residue, especially if you didn't use solder intended for electronic use. Alcohol usually does the trick and won't harm the electronics.

Great! Electronics, that's above my pay grade.

Thank you... I was wondering about that.
