Kitchenaid side-by-side fridge-freezer is not cooling

SOURCE: Fridge not cold...freezer is ok.

Hi and welcome to FixYa,

Initially, this normally would point to the fan not spinning. The function of the fan is to draw the cold air from the freezer and force it through the vents to the refrigerator area. Even having said this, the fan is activated by the logic controller based on the the thermostat setting of the refrigerator and condition of the door (it must be closed).

Good luck and Thank you for using FixYa. Happy Holidays.

I had a similar problem where the refrigerator side was not cooling well but I could feel very little air coming through the vent in the top left corner.I blew hot air from a blow driver into the vent for about 1 minute which melted ice that was hanging from the bottom of the vent cover.Cold air started blowing harder thru the vent and cured the problem.

You have an issue with the defrost system, either the timer, thermostat or heating element. Probably the defrost timer refer to the manual to find it. If you don't have the manual check the makers web site for a parts breakdown. You should be able to put it into defrost manually by turning the knob and see if that helps. You may need to do this sevral times as it only stays in defrost for a little over twnety minutes and run cycle for 6,8 or ten hours. If the ice build up is heavy then twenty minutes may not do the trick thus the need for repated defrost cycles. If it does the trick replace the timer. If not check the thermostat and heater element.

if you have frost build up on rear wall of freezer section then your unit is not going through defrost. its either defrost heater, defrost thermostat (which are both located on evaporator) or defrost timer

Have you checked the damper at the top left hand side, could be frozen - take it off thaw it out and replace. The freezing could have damaged the unit though.
