JennAir 30"elec.slider downdraft unit/ blower location issue.

It is possible to remove the downdraft equipment from underneath your JennAir electric cooktop and still use the cooktop, but it depends on how the downdraft equipment is attached to the cooktop and whether there are any other issues that may arise from removing it.
Before attempting to remove the downdraft equipment, you should consult the user manual or contact JennAir customer service to ensure that it is safe to do so and to obtain any specific instructions for your particular model.
Some potential issues to consider when removing the downdraft equipment include:

1. Airflow: The downdraft equipment is designed to help draw smoke, steam, and odors down and out of the kitchen. Without it, you may experience reduced airflow and ventilation, which could result in lingering odors or smoke.
2. Heat distribution: The downdraft equipment may also help distribute heat evenly across the cooktop surface. Without it, you may experience hot spots or uneven cooking.
3. Stability: The downdraft equipment may provide additional support or stability to the cooktop. If it is removed, the cooktop may become less stable or secure.

If you decide to proceed with removing the downdraft equipment, it's important to follow all instructions carefully and to take appropriate safety precautions. You should also be prepared to address any issues that may arise as a result of the removal, such as by using an alternative ventilation system or adjusting your cooking techniques to compensate for any changes in heat distribution.
If you're unsure about whether or how to remove the downdraft equipment from your JennAir electric cooktop, it's best to consult with a professional technician or contact JennAir customer service for guidance.

If I can get the model # I can help you more with the removal and reinstall.

hi there,

initially downdraft ranges from 6oo CFm to 1600 CFM within the pushbutton control.

CFM means (cubic feet of evacuated air per minute)

Hope this initial info/idea helps.

Let me know for further clarifications,

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!

good day,

I would double check that the installer used the correct vent hood outside. The correct one has a spring that keeps the outdoor flap closed when not in use. Cleaning the outdoor flap area may also help it seal a little better. Even if the right hood was installed, you might check to see there is a spring present (or signs that there was one.

I have never had air blow out the downdraft, but I do feel cold travel to the fan unit which makes the floor cold in front of the range.

replace whole unit thats roughly what the whole unit costs 157.00 just a little secret there they dont tell you cause they mark up the prices i worked for the company that sold and installed this equipment you also remember tax

bibman: Sounds like the control switch or possible loose wiring. Take the element out and test the slots for voltage. You should get 220 Volts when on high.


DMA Jennair The fan motor is bad and needs to be replaced.

I suggest a new cooktop as THIS IS THE WORST DESIGNED COOKTOP I HAVE EVER USED. Not enough power, very hard to clean,

If you're talking about a downdraft style cooktop, you will just need to measure the discharge vent diameter and shape and match that up. Not all are the same shape but most are 6" diameter
