I have a Jenn Air with a broken glass cooktop. I think you have a replacement part in stock, but do you have installation instructions? Is this something I need a technician for?
Answer Hello Mike,
As per the service manual:
Main Top Removal
1. Disconnect power to cooktop.
2 Remove cooktop from installation position and place face down on protected surface.
3. Remove screws securing main top to burner box bottom.
4. Remove screws securing control panel box and conduit mounting plate to burner box assembly.
5. Remove main top.
6. Reverse procedure to reassemble, verifying that cooktop frame is properly aligned.
NOTE: Make sure the pieces of insulation, located in the front left and right rear corners, are put back in place. Failure to do so could create excessive cabinet temperatures.
The service manual does not mention that if the power is disconnected and the unit is placed diagonally over the countertop opening, it can be serviced without disconnecting the power supply lines from the junction box. You do need to use some towels or similar items to protect the countertop.
