There is a big model list more recently added as of this posting, manufactured under Whirlpool Brands, that you can find on top-class actions that have a combination of problems from design, manufacturing - parts. I have model # WRX986SIHZ00 French door "dual evaporators" RC not cooling. FC works perfectly. The first place to "START" is the 3-way refrigerant solenoid valve and install a new receiver dryer simultaneously. This 3way valve is part of the sealed refrigerant system. Externally, the solenoid valve slides onto the refrigerant valve that magnetically turns the internal refrigerant valve either to FC or RC, so the refrigerant is directed to each individual evaporator compartment. The internal valve is defective and getting stuck in the wrong position. Currently, there is a back order on a new solenoid and refrigerant valve design. This combination can also cause "electric control boards" to become defective and have to be remanufactured. The manufacturing defrosts defect causes will be no ice cube production, warm in either FC, RC, or both. Ice build-up on RC evaporator middle drawer pushing out from ice build-up etc.
