The timer/control module on my jennair electric oven keeps blowing up. I installed a rebuilt unit it worked fine for 2-3 minutes then blew up

Jennair says the fix is easy. It is a 'stuck' key which is causing a 'short' which actually isn't, but permanently on, closed circuit, you will need to get under the keys and clean them with electrical switch cleaner. Or you buy a new button module and control board for 1,000 bucks, thank you for buying Jennair!

I think that is a problem with the control assembly.

Try first unplugging power cord for ten minutes , and see if this clears the error message.

I couldn't find any information on that specific model number, but here is a link to a generic Jenn-Air Electric Range - Use and Care Guide which seems to be model non-specific. The instructions for performing a self-cleaning (as well as other tasks) might be the same for yours.

Part # 71003424 runs around $185.00
It's a common issue in Jen-air ovens,the display burns out,the control itself will still work fine but you just can't read it.

F1 Power to element relay energized during time of day display.
1. Wiring harness shorted.
2. Or change power relay board (PRB).

Note: for double ovens, change second oven board.

douglas9101,
I had the same problem and found the solution on-line.
Replace the C3 capacitor on the dispaly module. (100 UF, 35 volt, high temperature)
The local Jenn Air dealer wanted $211 for a new display module.
I purchased a Cap from a local electronics supply store for 79cents.
The only problem is that you need to have a soldering pencil/iron, a solder ******/wick and a small amount of solder.

Steps I had to take on my oven:
- Flip the AC breaker supplying the oven to off to be save
- remove 3 screws on top and 4 on the bottom of the display panel
- gently pull out the display panel and unplug the 2 cables to the display
- unclip the ribbon cable to the display module
- unclip the module itself by pushing on the 2 black tabs
- locate C3
- unsolder C3 and replace with new Cap- keeping the polarity strip the same as theh old Cap
- reasemble in reverse order.

It took me all of 20 minutes. It may sound difficult but is very easy if you have the tools
Good Luck

Bill ,i dont suspect the control unit is the problem im going back to the loud pop you heard I would say the pop you heard was one of the elemants blowing and that the reason the the breaker tripped if you say the clock,timer and light functon are ok it more so points to an elemant in most cases when an elemant blows it breaks the circuit .but the other componants also work when you reset the breaker i think in this case bill i would call a electrician it needs testing,sorry i could not help this time bill,but do not hesatate to contact me if i can help you again.adrian

hi The range timer is usually located in the control panel on top of the range. If you suspect the timer is faulty, don't try to fix it yourself. Remove it and take it to a professional service person for testing. Here's how to remove the timer:

Step 1: Remove the back service panel to the control panel and release the spring clips that hold it in position, or remove the retaining screws.

Step 2: Push the timer forward to release it.

Step 3: Remove the electrical lead wires from the timer housing. If, when disassembling the timer, you notice that the electrical wire terminals look burned, remove these leads and buff the leads and the terminal points with fine steel wool. Burned and/or dirty terminals can cause the timer to malfunction, but a good cleaning can solve this problem.

Step 4: Replace the old timer or install a new one of the same size and type, if this is necessary. Connect the new timer the same way the old one was connected.

It appears that the timer has gone faulty, possibly because of a short in the bulb holder, which probably explains why there is no display and the main oven not working. the top will still work as it is not controlled by the timer.
the solution hear would to be fit a new timer.

replace the control cpu unit the main control board is deffective
