Ignore the chowder-heads who think a 1970's Jenn-Air Drop-In Downdraft Range has self diagnostic codes. The oven thermostat has a copper tube that goes from the control knob all the way to the right upper wall of the oven. That contains a fluid that expands a bellows in the control. The knob adjusts a sprung teeter-totter to remove the power from the element when the desired temperature is reached. Sometimes a controlled poor temperature control because it is gummy, sometimes the fluid system has malfunctioned, and rarely the mechanical teeter totter or electrical contacts have failed. You can clean a gummy control with an electrical or electronics spray cleaner from an auto parts chain store or an online vendor. Use some paper toweling around the control to soak up the greasy solvent. Do follow the directions below for replacement to gain access to the bottom of the control and to move the control down from its installed position before attempting to clean it. Electronics Cleaner sprayed carelessly can remove the markings from the control panel and the number wheels of the clock. (BTW if your clock is stopped its rarely burned out, just gummed up and stalled. it can be removed and opened up and carefully degreased using cotton swabs and it will run again. The place to degrease is the gears closest to the round metal can clock motor, and when necessary inside the clock motor can. Don't touch the clock's number wheels for anything, the white paint can weaken with age and wipe off as if it only holds on by habit. The motor can be stalled indefinitely without damaging itself so it should be able to start up again when powered, it has very little force until it's multiplied by the gear train, so it's usually stalled by the early gears. If the clock wheel gearing is gummy enough to stall it when it's time to shift a digit or turn over multiple digits I suggest trying to use a thin cooking oil on a cotton swab to dissolve the grease and swab it away before trying anything more aggressive that is harder to control and may find its way onto a wheel face more easily, The timer gears are only engaged when the timer is running, resolve any gummed timer and chime gear problems after the clock runs correctly.)

To replace the oven temperature control;: Disconnect the power, and make sure it's off, you'll be working where you could touch a live wire, Open the oven door and remove the 4 screws holding the black cover under the controls. Remove the oven temperature knob, remove the nut holding the control to the panel. Migrate the existing control down to where you can shift the wires one at a time to the new control. You should be able to see the path the oven temperature probe follows. If you find you need to remove the control panel to thread it It's better to wiggle the drop-in out a bit to get to the screws left and right than to disconnect the flexible exhaust sleeve to move the range freely, because the exhaust can be a bit of doing to reconnect - mainly because you'll notice it's a greasy mess that has to be cleaned. Withdraw the old probe and install the new one. If the stand-off clips on the oven wall are missing or damaged they have to be replaced, it can;t just dangle. Close the wire tray and turn the power back on.

There is a high limit thermostat that will cut all the power to the upper oven elements. Their is a wiring diagram in this link
when clicking on it,it will say not avaliable. A trick i have found is to open that link and then using your computer tools select the maximum zoom i use IE set to 400% and its pretty ledegable.

Jenn Air Range Model 88370 oven only bakes in the back and leaves food raw in the front.

It will be the oven element that has failed, a new one wiil need to be fitted.

It is located at the rear of the oven compartment behind a removeable cover.

I hope this helps.

Instructions to replace Jenn Air oven thermostat

To remove the control panel, open the oven door wide as possible. Remove the screws from the top of the CP and the screws from the bottom of the CP. Grasp the CP bu placing hands on the right and left sides of the panel, pull out and down to disengage. Depending on manufacture run you might need to lift up and out to diengage.
Have a cloth on the oven rack to lay the control on so you won't scratch the pretty facing. Once that is done you have easy access. Wear some rubber gloves doctor, this prevents harm to the electronics. Static discharge is a no no around expensive electronics. You can do this. Take your time. Piece of cake.
You will be able to check high limit cooling fan door latch and motors 9if applicable on your model) cool ain't it?

Oven and stove top not getting hot.

The most probable cause is that the heating elements are getting 110V instead of 220V. Check the voltage to the heating elements.

Every time I have seen this problem, it has been a bad display assembly. These are fairly easy to change yourself, but the part is kind of expensive, I think in the $150-$200 range. Hope this helps!
