SYMPTOM/CONDITION:
On the listed models, a roll pin is used as a door hinge pin that may be difficult to lubricate. A lack of lubrication may result in a noisy door hinge or a
stiff operating door. A new solid hinge pin and a teflon impregnated self-lubricating bushing, used in production (MDH 02-18-XX and later - front door
and MDH 01-28-XX and later - rear door), are now available in a service package.
