#296382 Kitchenaid downdraft fan kird861vss1

Posted by OaklandBob on 14 June 2014 - 08:48 AM

Our KIRD is in our kitchen so I don't have to walk very far to raise my blood pressure.  Our original problem was caused by a power surge on-off-on that killed the unit.  The motor fuse was blown ( overload ) and the snorkel had moved past the upper limit switch into a mechanical stop.  I shut off power to the unit, moved the upper limit switch out of the way, lowered the snorkel a few inches with batteries, replaced the limit switch and the fuse, applied power, pushed the raise/lower button and the snorkel raised to it's proper position and the fan operates. We always keep the unit in it's raised position unless we are cleaning it and as long as the power is on to the system it operates normally.  If power is lost we are back where we started:  when power is restored ( snorkel up) a brief push of the raise/lower causes it to move past the limit switch, a longer push of the button drives it into the stop and blows the fuse. Something happened to the electronic control board that fouls up the sequence of operations and I don't want to buy a new one ( $300) and have it happen again. What I have done is this:  after the last power outage I followed the procedure for lowering the snorkel and getting it back into the proper position and then removed the fuse so the motor wouldn't operate. Now if power is lost or removed the fan won't operate until the raise/lower button is touched and then everything is fine. See my other posts for more details on what I did.

 

I would be very interested in getting a failed control board to look at and would pay for postage/handling etc.

#256292 Jenn-Air and KitchenAid Retractable Down Draft Vent System

Posted by OaklandBob on 29 May 2013 - 04:38 PM

PDuff - We are back in service.  The plug on the wiring harness for the gear motor is an ALEX (Taiwan) 8097 series that uses .045"

square pins.  I made up a couple of test leads with #17 solid wire (.0453") that fit right into the plug. To power the motor I used 2 - 12  volt gel cells in series.  I removed the upper limit switch and lowered the snorkel ( black lead positive lowers, red lead positive raises), replaced the switch, fired up the unit and everything works fine.  Some sort of glitch caused the snorkel to raise past it's

limit but the access plate allows you to see what happened in this case.  I think I'm going to keep the Cook N Vent blower in place

just in case.  Thanks for taking the time to check for more info for me!  Bob
