Fisher & Paykel RF201AHUSX1 French Door Repair Help

The RF201AHUSX1 is the ice and water version of the current-generation 20.1 cu. ft. Series 7 French door line. It stands free in the kitchen, so we can reach the back panel and the condenser without opening any cabinetry.
A dispenser that has slowed gets the filter, line and valve in that order, and we measure flow rather than guess. Temperature drift sends us to the ActiveSmart sensor, which we test against a thermometer before we replace it. A drain clogged with ice can send meltwater under the crisper, so we flush it and confirm the defrost heater clears the coil. Afterward we draw water and run a short ice cycle to verify both paths.
A written price comes before work, and a 30-day workmanship warranty covers the repair.
