Question about Jenn-Air JJW8530C Expressions Collection Dual Single Oven
The exhaust fan seems to start working when the oven reaches a warm enough temperature....but, you can hear it whine up and down as the oven cooks in fact, when you think it should be on to exhaust the heat and cool the oven down AFTER the cook cycle is done, the fan is noticeably silent and obviously off. We think this is a problem but not sure what component is causing the issue. I cannot seem to find any related issues on any forums so I am hopeful someone here at FIXYA has some guidance/ideas.
In not sure but i think that fan runs off a thrmistor that goes to the contol board.open the oven door and look on the right side of the oven see if theres a metal looking bulb.

thats the thermostat bulb.if there are no other sensors inside the oven compartment the thermostat might also be controlling the fan.if you can trace where that bulb goes to see if any wires/boards look burned.i will try to find a schematic for you.
still looking for a schematic.there has to be a probe to turn that fan on and off.like i said it could be sensed by the t-stat,if you find where the wires run to (like the control board)either the probe is bad or the board.how old is the oven?
did that part connect to a board?see if you notice any other wires coming off the board.look for a plug with just 2 wires in it and unplug them.if that is the only thing that you removed and it was connected to the board your control board is bad.

ok - I located a metal probe (back left towards top inside oven) and a round 'screen' on the top of oven in center)...no thermometer or thermostat. I'm not sure what I was supposed to do once I found it anway.
Any other ideaS?
ok..I am with you so far - I will try and remove that item and see if any wires are burned/worn.
One new thought is that the fan seems to turn off when the temp gets higher than a certain temperature (whereas it does seem to properly come 'on' when it first begins to warm up).
Does this signify anything with it being 'temperature' driven (a thermostat issue vs. a control board issue)?
the oven is 5 years old
frankly the oven is a total piece of crap but we're not in a position to swap it out for new yet. It's one of Jenn Air's finest which had the defective door hinge issue (well-publicized). We finally had someone fix that to the tune of $150 last year so we have enough invested in the current one to seek inexpensive ways to fix this current issue.
I'll plan to tinker with it this weekend to see what I come up with the wires.
I've pulled the probe/thermometer out and noticed no burned or disconnected wires.
The oven seems to function the same as described previously even after pulling this part out and putting it back in place.
What's next?
