After using the broiler a sound like a fan starts

Can you get to the switch terminals and try jumping them out with a piece of insulated wire? That would tell you if the switch is defective (my suspicion). Please be careful not to touch any live terminals - only the wire insulation you use for the jumper.

yes you are right..there are switches that should be detected that the unit is in its proper level ans hould stop and turn the fan on.

you may inspect the railing or where the moving part is moving to find limit switches or sliding switches or sensors..it could have been defective with oil or grease and not making contact to transfer the signal to the controller.

tnx 4 using fixya,

I think you will find it to small to fit behind the range top

Remove the motor together with the blower wheel, go to the local self service car-wash and use the engine de-greaser cycle (if not available, buy a can at the auto supply, spray the fan blade and let sit for a while) and get all the grease of the fan blades. make sure the fan blades are cleaned thoroughly. the fan will now ran quietly and will remove all the grease away. in the future, clean the filters often.

The downdraft is electric so there must be something malfunctioning with it. It is a high volume downdraft fan that is to be vented to the outside. Could it be that something has clogged the vent hole up, not allowing the fan to evacuate the smoke?

While I am not a big fan of Jenn-Air, their fans are usually high quality if they are installed correctly, with the proper vent lines.

not that I know of but the fans on these ranges usually have multiple speeds. Try using the lowest. The fans are very strong on them. Hope this helps. good luck.

some times the wall nest to the vent when is wendy, it force the air in side, i recommend to replace the vent position out side.

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!

open your cabniet up under the unit you will have to disconnect the venting in this will give you access to the blower section also make sure the filter is not hitting it inside they usally install a screen to prevent this but maybe yours is missing
