Side by side doored, Hotpoint 27.7 cu ft model. Water tap in front door access (next to icemaker outlet) has a steady drip. Notice I can't access the top screw to pull out the assembly. Removed panel on inside of freezer door and some of the insulation, but looks like even access there will be limited. Do I need to somehow disassemble the entire freezer door or am I overlooking something easier?
