Electronic Clock Control Board

Removed the 4 phillip head screws that hold the trim plate on the bottom of the display panel (and you probably could skip this step).
Next, I removed the knobs from the front of the display panel.
Then I removed the 4 phillip head screws that were located (1 each) behind the knobs.
Finally, I removed the 4 hex head screws from the bottom of the front panel.
You caan then remove the panel a few inches and remove the two cable connectors.
The trick part is to get the flat ribbin cable disconnected. If you squeeze the two small tabs (one on each end of the connector), the connector moves up and spreads open to CAREFULLY remove the ribbon cable.
The clock assembly has just two hex head screws holding it in place. Remove them, and reassemble everything in reverse.
If you did everything correctly, you should have a very bright stove clock again!

Was about to spend 2000 on new oven and decided to check here. At least 15 stories with same problem and solved. Add one more.

Only thing new to me was ribbon connector. Didn't really pay attention when I disconnected from the old assembly. When you squeeze the ends of the connector, part of the connector itself rises up to release the ribbon cable. Remember this when reinserting the ribbon cable on new assembly. If I hadn't followed the "If you have to force it, it ain't right" rule it could have gone bad.

One of the easiest repairs I've done in a long time!

First I turned off the power to the oven at the power box.
I removed 4 hexhead screws holding the front contol panel on. Tipped it out, and then removed 2 hexhead screws to remove the clock module and unplugged the wires. Reversed the sequence and
turned on the power again.
The trickiest part was checking how the wires were held in - easing the catches back while gently working the wires out.

I also replaced a grill element with a new radiant element cartridge. That was easier than replacing a lightbulb.

The front oven control panel was already in need of replacement. The digital readout had quit working sometime ago, so we began by replacing the control panel as well as the temperature probe. Neither of these items did the trick. Next I replaced the HI/Lo sensor switch. This replacement was a bit more labor intensive. Have to remove several screws and remove a large portion of the top of the stove. Once access is gained to the hi/lo switch, it takes (2) minutes to replace it. This of course did not take care of the problem either. Finally I replaced the bake/broil/convection circuit board. This was a bit of a job, only because of the amount of wires to and from this board. I litterally took a picture of the board (from this web site) and drew in the wires and marked them by color and noted where they went. I then merely unplugged each wire and with one screw, removed the board and installed the new one. After plugging in the wires as per my picture, SUCCESS. The board did the trick. Over all, it was not bad doing the work myself. I know we saved a lot of money my doing it ourselves. Just gotta have patience.

First I turned off the electricity to the stove.
I then removed the 4 burner dials from the front panel. Then I removed the 8 screws under the front panel. Removed the triangle side pieces - 1 screw each. Slowly pulled the panel down and out and turned it face down so there was easy access to the back of the digital clock. Unscrewed the 2 screws that hold the clock and replaced it. New clock worked perfect. NOTE: Included in the repair - I cleaned and repainted where there was grease and rust.

I did this job myself, but it might be handy to have a helper to assist in holding the control panel during unplug and replug stages of the process. Also strongly suggest you read through these and other posted instructions BEFORE getting started.

Kill Circuit Breaker Power To Unit.
Pull Four Burner Control Knobs off front panel.
Unscrew Phillips Head Screws from under each knob. (Be careful not to strip screw heads, I applied pretty firm pressure on screw driver to avoid stripping).
Open Oven door.
Remove 4 Phillips screws on trim piece under control panel and remove trim piece.
Unscrew 1 small Phillips screw on each side of panel to loosen plastic side trim pieces.
Use socket to remove 4 hex head screws holding control panel in place.
Gently pivot control panel top downward to access the circuit board panel. BE VERY CAREFUL NOT TO ALLOW CONTROL PANEL TO HANG BY FRAGILE CONNECTING CABLES!!!
GENTLY unplug the two white connector cables from the board. There is a locking tab on both that you can release with a fingernail or small flathead screwdriver while gently pulling the connector upward. (These connectors snap to lock more easily when you eventually re-assemble to the replacement board).
VERY GENTLY unplug the ribbon cable. This was a bit confusing to me at first, but if you gently squeeze the two very small tabs on both sides of the black connector, you can gently raise the center body of the connector upwards about 1/8 inch. (You might find it helpful to practice how this mechanism functions on your replacement part BEFORE you do the disassembly, it's really pretty simple once you see how it works). This will take the gripping pressure off the ribbon itself and you can gently wiggle the ribbon out free from the connector taking note of the two very small alignment holes in the ribbon connector as you do so.
Now with all cables free use a socket to remove 2 hex head screws holding the circuit board to the control panel.
Now install the replacement board by simply doing all above in reverse. Take care to line up cable connections to the board properly, noting the two alignment holes in the ribbon cable to tabs in the black connector. All three connections should snap in easily without undue force.
Your range display should be good as new.

i'm writing this several days after installling parts and from memory so forgive me if i miss a step or get the # of screws wrong.

Clock assembly replacement was very easy. Open oven door and remove screws just below the display panel, remove burner knobs and remove the 2 screws hidden by the knobs, remove the 2 screws holding the side triangular pieces (1 screw for each side). you may need to pull range out and away from the counter to remove the triangle pieces. remove the display panel, flip it over and remove 2 screws holding clock assembly. gentle remove the ribbon cables from the old assembly and then perform everything in reverse to reassemble.

Replacing the igniters was more difficult and took up the bulk of the time. Warning: find some way to test the spark module first. I replaced both igniters (1 wire was broken so it needed replacement for sure, but the other igniter may have been good...) and they still do not work. I'm waiting on delivery of a spark module.

remove all burner stuff (grill, burner assembly, etc.), then remove the top of the stove, there are 2 screws on each side and several in the back, there are also screws around the inside rim of the burner pans. also remove the panel on the back of the stove, this allows access to the spark module. gently lift the burner pans, reach underneath the pan and unscrew the nut holding the igniter in place. fortunately mine were easy to unscrew and i could do it with my fingers, getting a wrench underneath would have been a challenge. unhook the igniter wire from the spark module and remove the old igniter. install new igniter in reverse and reassemble.

Turn off the power! Removed 4 phillip headed screws from beneath panel, (not the smaller phillip head screws at the each end). Gently tilted out the control panel, disconnected the wire harnesses, removed hex screws attaching clock assy to switch membrane. Cleaned a few items before re-assembly. put everything back together... You'll be surprised how bright the new assembly is...the old one gradually dimmed to the point it couldn't be read.

The hardest part was learning how to access the electronic clock assembly. Once I figured that out the rest was easy. Finding your web site to locate parts was great. Having the esploded diagram for the Jenn Aire was very helpful.

First I removed the two screws that hold the bake element. I then pulled it out far enough to disconnect the two wires, and reversed the process to connect and secure the new element. I then removed the screws located under the control panel that held it in place. I removed the wiring, 3 cable connections, from the clock circuit board, and the two screws holding it in place. I installed the new circuit board, and reconnected the wiring, and returned the control panel to its place. The wife was upset that she had offered to do some of my chores while I fixed the oven when she found that it had only taken me 10 minutes to make the repairs. The parts were a perfect match, and the job couldn't have gone any smoother.
