Hi,

You will need to remove the cabinet to change the bulb, the part number is 4359741, now the bulb is part of the base so the part number is the correct part for this model. Good luck

Please post a new request that includes your detailed symptoms are well as the full model number.

That model number from the tag on your oven should be KCMS1555SS0, KCMS1555SS1, or KCMS1555SS2.

We would need more detailed information about what it's doing or not doing.

Does it respond to key presses?
Does the inside light come on when you open the door?
Can you enter the cooking time?
What happens when you press "Start"?
Does it run but not heat?
Does it count down but the inside light and fan do not come on?

Please post a new help request with the model number and detailed sympotms.
