Hi glors732,m

A chip perhaps, but not a crack, you will need to replace the whole glass panel. Will be quite expensive though.

Kind Regards

Replaced main glass cooking surface on cooktop

First, shut of the breaker to the cooktop.
Then removed two screws to release brackets holding cooktop down. Then lifted the cooktop out of the recess in the counter top and removed the screws around the outside of the glass top. Removed the old, cracked top, by unplugging from the motherboard.
Turned the new cooktop upside down on table and placed weather stripping around the entire underside outside edge (to keep spills from going under the cooktop and cushion the cooktop from the counter top.
Then plugged the new cooktop into the motherboard, replaced screws around outside edge, lowered the cooktop into the recess in the counter, and reinserted the two screws into the hold-down brackets.
Turned the breaker back on.
Note: Just need Screw drivers and 40 minutes of your time.

Only a couple things would cause this First if it is to tight in the opening. Next is there was a small crack on the edge somewhere and when it heated up or the slightest vibration expanded it similar to a small chip in a windshield that grows over time.This could easily happen during installation if not being very careful. And finally is a defect in the material, This is probally unlikely but possible look at the glass very carefully for flaws. If you find any see if LG will repair for free.

A small crack, turns into a big crack, Short of ordering a new piece of glass, there is no "fix" sorry. YOu can continue to use it, but eventually it will run across the cook top, and then shatter the glass... Better be safe than sorry.

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.

when ordering you would have to know the color also

Yes. It is. i always feel weary when i see it to however the top is not glass its ceramic so it is a little stronger.if you are in fear wrap tape all the way around the top and tight. if the top is tempered then wrapping the tape around it would make it almost indestructable.

The cook top is attached to the wood frame by brackets, just remove the screws and the electric connection, make sure the power is off from the main box, it's a 220 volt wiring and then just lift the top off. to remove the glass, look around the edges and you should see some small screws, just remove them and the glass should lift off.

You probably need to replace it. They are though fairly expensive. A little under $200 to be exact. http://www.partstore.com/ModelSearch.aspx?MfgName=Maytag&BrandName=JennAir&CloselyRelatedModels=true&ModelNumber=JED8430&x=41&y=30
