Whirlpool WRF535SWHZ Repair Guide
Whirlpool’s volume french-door box — conventional single-evaporator design with a bottom freezer, which makes it predictable to service: defrost problems show up as "fridge warm, freezer fine," and the ice maker is a standard modular unit with cheap parts availability.

Tech notes
The defrost drain on this platform clogs enough that techs carry the fix in muscle memory: flush with hot water and install the accessory drain clip so the heater keeps the hole open. Cheap and permanent.
