Thermador UCV36 Cook'N'Vent Downdraft System recoouring part replacement

I have had issues with this Thermador Downdraft system since I bought it. There is a part that has to be replaced about every 9-12 months. It would need to be replaced more often except that I don’t cook very much. The repairman suggested a design flaw in this unit. Apparently the design problem has two issues: 1) is that the yoke is a piece of flat sheet metal bent into shape instead of a more durable part - in not only bears all the load to drive the vent up and down but it also does so by a twisting action which causes more stress on this flimsy part; 2) is the only thing that holds the filter assembly on the yoke is gravity, it is not secured on it. Can anyone offer an alternative fix? Every time I have to get it fixed it costs me $250-350.

    I have the same problem on my RED30V Thermador. Thermador no longer makes the part for mine. Where do you find the yoke? Maybe the one you're using will work on mine?

sears labor is 137 plus parts. that is something that would need to be looked at. it could be a few different things. if he is handy he can open it up to see if anything is misaligned or broken. the vent may even just be a little crooked and once straight may go up and down like normal

I have three 90s on my downdraft unit - 90 down from unit into slab, 90 out from slab to outside, then 90 down again. If you are talking a 6" or 8" dia vent it should not make a difference at all.

SOURCE: Thermador CVS36R Cook'n'vent vent won't go down and fan stopped workin

You probably will find that the vent is clogged with grease. A switch device works with the vent so the fan operates only when the vent is open and does not operate when the vent is closed. Things should get back to normal after a thorough cleaning unless the fan is defective and won't operate at all.

Up & down push button not working


Repaired the same problem several months ago. The up/down control has a very small switch located under the button. The switch is part of the selector switch assembly that costs upwards of $100. However, the switch itself is available from Digi Key electronics part # P12321-SCT-ND at about $1.00 each, plus shipping. If you can handle the unit disassembly, which is extensive in this repair, and can solder very small switches, this is an inexpensive fix. I suggest you buy some spares. I'm looking for a seal replacement for this unit right now. Good luck.

Cook 'n Vent Downdraft Up/Down Mechanism Replacing


just the switch should be replacable. My vent has a screw at each end (philips flatheads - accessible only when vent is up) just under the top cap. Removing the screws and cap should give you access to the switch. Just make sure you cut your breaker off first.

Thermador cook top with down draft ventalation


I would think you can. Most of the cooktops are 240v and the vents are 120v, so the vent may be feeding off of one of the cooktop's hot wires. My vent is fed from it's own receptacle but is harnessed along with the cooktop's 240v.

Install a Thermador UCV36 cook'n'vent


Hi schmidt_rich,

I'm Harvey the Master Plumber.

Your question is: You took over as owner builder when your builder "took the $ and ran". You are installing kitchen cabs now and discovered the PVC vent pipe (which goes into the foundation and out the side of the house) is in the wrong place for the location of the downdraft unit and integral blower. The vent is actually under the electrical connection panel. You were told initially( 2 yrs ago when you bought the downdraft cook'n'vent) there could be no bends in the exhaust fan route or it would change the effectiveness. Does anyone know if it is ok to put a bend in the connection to the vent? Or do you need to redo your kitchen cabinets?

I can syphathise. I have had to deal with this same problem. I have found that one ell will not degrade the effectiveness enough to notice. If you need more then you may need to adjust cabinets.

Feel free contact me again!
