Are step by step instructions available for changing the wrapper oven cavity assembly?
Unfortunately there are no written instructions on how to remove the oven liner assembly to replace. In order to do this you would need to remove the oven door assembly. Once removed there should be 3 screws at the top and 3 screws at the bottom of the opening of the oven door. You will need to remove the screws and the oven liner should be able to slide out from position.
How difficult is it to replace the wrapper oven cavity asm. on our JTP30BM1BB model wall oven? We have Reynolds Wrap melted on bottem of oven.
Answer Hi. I am sure you tried to soak it with oven cleaner to see if it will loosen it from the cavity. Replacing the oven cavity part # WB63T10128 is a doable effort but is a very labor exhausting issue. Just make sure all of the oven outer insulation wrap is exactly placed back as the manufacturer designed it. For cavity heating purposes and to protect the outer wiring and devices from melting etc..... Thank You.
