Door spring replacement tip worked fine.
Light bulb a little more difficult. Could not move complete oven from the wall without causing damage to decorative molding...
Solution; metal trim on sides of the oven has screws towards the bottom end- when removed -the trim can be slid down and off. This exposes the 2 screws on the control panel - when removed - panel can be moved enough to take out the vent and the microwave can then be slid out enough for the bulb to be replaced.
