1. Turn off the power at the breaker box.
2. lift off the air grill.
3. remove the two screws at the front of the control switch panel (escutcheon)..
4. slide the control panel forward until it disengages, then lift up to expose the switch assembly and wiring.

The top can not be repaired. The glass must be replaced . DO NOT USE IT CRACKED!!!!!!!!!!!! This is very dangerous as it can explode from the temperature. Also this is a severe electrical danger as glass top units have exposed elements underneath. Any liquid at all can short it out and cause a fire. I don't know if it is worth repairing. I don't have the exact price for your cooktop but last one I priced was between $350 - $500.

Yes you can. Call Jenn Air ((877) 232-6771) and give them your model number (serial is helpful too). They sent my replacement glass within a week. I have a model JED8430ABD from 2000 and they had the top. Fit perfectly and took about an hour to replace.

To change it out, after unplugging the cooktop, I removed the metal tape connecting the external vent shaft to the blower. Then I just lifted the entire cooktop out up out of the countertop so I could access the screws on the sides of the cooktop (looking at the edges of the new cooktop glass helped me figure out which screws to remove around the edge). Then I removed the 2 screws in the vent area on top (1 black screw on each side). And that released the cooktop glass from the metal box that holds the burners. I then took the rubber rings out of the knob holes so I could put them in the new cooktop (I almost missed that...). Finally, I put the new cooktop glass on, put the screws back in, lowered the cooktop back into the counter, and retaped the blower to the vent shaft. Voila!

I really wouldn't be afraid of doing this yourself if you are handy at all. And it will save you a ton. Good luck.

PS The screws around the perimeter are hexigon shapped, so you can't just use a screwdriver. I found my Black & Decker electric screwdriver had that same shaped hole that it held the bit, so I just pulled out the bit and used the screwdriver that way. Worked like a charm.

Looking up the service manual - it is no longer available.

Hope this is helpful.

Thanks for using FixYa!!

Epoxy would not work. If it is a very small chip and is NOT STRUCTURAL or in the heated are you could TRY the adhesive used for rear view mirror to glass attachment.
