Jenn Air StoveTop Fan Operation

[G***@JayMontero.com]

We bought a house with an existing Jenn Air gas stovetop installed. We
thought there was a wiring problem with it because the exhaust fan
comes on automatically (and cannot be shut off) whenever the left side
burners are used. We learned from a repair company that this is how
Jenn Air designed this unit. Can anyone tell me why in the world they
would do it this way when there is a switch for the fan within easy
reach right on the stovetop?

Another weird thing is when you fire up one of the burners, all of the
igniters light. Again, this is as designed. But every now and then,
you can hear one of the other igniters firing but the one you want to
light doesn't. Eventually, after a few tries, it does. Annoying, but
at least it works.

Can't speak for JennAir, but my over the range microwave does the same thing
if the temperature gets too high. It is a safety thing to prevent damage
from overheating.

The mulit ignier is probably as much for simplicity in wiring and
manufacture. On our Roper there are two igniters for four burners. No
matter if you turn the front or back knob the same (only) ignither on that
side works.

Cannot speak for the gas version but on the electric tops the left side
is automatically assumed to be the grill and apparently they assume that
if the grill is on the fan will be needed and always on high speed.
Unfortunately if I put the griddle over there or plug in the extra
burner module to use an oversize stock pot that the halogen module on
the right won't handle the fan still comes on. Can't locate my manual at
the moment but I don't think there is any workaround.

One thing I've been known to do is to reach under the stovetop and pull
the plug. That stops the fan from blowing, but I have to remember to
plug it back in so the igniters work when I need them.

Just use one of those torch lighters, like are used for lighting candles
or a BBQ. That's what I have to use on the gas stove when the elec.
power goes out.

I have a Jennair, electric, circa 1988 and the fan only comes on if I
turn on the switch for it. If I had one where the fan always came on,
I'd rewire it, because it sounds like a good way to suck hot/cold air
out of the house for no reason.

You'd probably be better off calling someone who does appliance repair instead of an electrician.

If you have to ask, probably not. Call a local appliance guy.

A model number of the exhaust fan would be helpful.

It's a JennAir. The exhaust fan is built into the stove.

Still, a stove model number would be lovely.

Doesn't matter. Gurlie is from Homemoaners Hub. She won't be back.

We have a gas Jenn Air which we bought new. The fan comes on only when
the grill or griddle is installed.

According to the wiring diagram there is a "pan switch" which is normally
closed. When the grill/griddle is installed there is no pan so the switch
is closed and the fan is on. There is a pin on the end of the pan so when
the burners/pan are installed the switch is opened and the fan is off.

Hope this helps.

Just another bit of info on the Jenn air fan.

I have the left side of our Jenn air set up with the griddle. As has
already been said, the fan comes on automatically when the griddle is lit.
I had assumed this was because we had replaced the grille with the griddle -
and that the fan was necessary when cooking on the grille.

Therefore, I thought the automatic fan was not needed for the grille. I
took off the front face /trim cover (take off knobs, take off face plate),
identified the wire that ran the automatic fan switch and disconnected it.
Sure enough, the fan no longer ran automatically when I lit the griddle.

The unfortunate part was that the griddle burners didn't really work
properly without the fan running - it seems like the fan (suction) pulls air
throught the space between the burners and the griddle and thus helps it to
burn properly. I re-installled the automatic fan wire and the burners
worked much better.

Just fyi, fwiw.
