Hello, I have a JP340B0A2BB GE cook top and the glass is broken and needs replacement. Can I replace it myself or do I need to buy a new cooktop? Thank you If you could also provide a few resources as to where I can buy either the replacement glass and/or the whole unit. Thanks Beth

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.

I'm sorry to hear this. you can get just the top, but your lookingat somewhere between 300-700 dollars just for the glass. also this is not a common part and will probably be back ordered, so you'll be looking at a wait of 2-5weeks for the part. you can change it yourself but due to the cost of the glass I would have a service company change it so that if it breaks while changing they will have to pay for a second one and you wouldn't be stuck having 2 broken glasses

TURN OFF CIRCUIT BREAKER. Lift out cooktop, remove all machine screws holding the glass frame. Remove plastic knobs and lift glass top straight up. Make sure rubber gromits are not ripped or torn. Unscrew the small screws on the selector switch and then lift up and tilt over the small aluminum chasis holding the switches to expose the wiring connections. Pull off the wires and pull out the defective switch. Replacre switch, connect wires, re-seat switch chasis, and secure switch with screws. Carefully drop in the glasstop lining up the switch shafts and the rubber grommets. Secure the top with machine screws and drop back in the cutout.

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.

It all depends on our capabilities... The top isn't all that difficult to replace. If it were me, I would call GE Factory Service 1-800-432-2737 or schedule an appointment online at www.geappliances.com as there may still be a warranty on the top which is expensive...

when ordering you would have to know the color also

Porceline (a coating over metal in this case) is actually a type of glass, and subject to fracture upon sudden thermal shock or physical stress. The part you indicate is WB62T10124 for a JGB939C1WW probably a bit over $150 or a WB62T10132 for a JGP939C2WW, probably a bit over $100, but the labor to replace it would be costly. If you rate this, please remember I did not manufacture this product, nor am I a GE employee, so please don't shoot the messenger.

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.
