Not to burst your bubble, its more than likely going to ice again. Those models are plagued with all kinds of different problems from evaporator fan thermistor failure to multiple board problems & points in between. Don't think you're out of the woods yet.
most likely your defrost thermistor or main pcb is the problem for ice
Wow what warranty plan is that? How much extra did it cost at time of sale and what was the additional years coverage beyond the mfg warranty?I always try and calculate if those plans are worth it.I read all the fine print and most say they are allowed to use refurbished parts or aftermarket parts or give you a similar style machine that may be refurbished if unit cannot be repaired so I never but those plans.Bottom line is whatever they gave you for the fridge, you have to deduct the cost you paid for the plan.
In hopes that it will help someone else with this problem, I just spent a week plus with a repair company trying to correct the PO Error Code Issue on my KitchenAid KRMF706ESS01 refrigerator/freezer. Here is what was the diagnostics and repairs performed: 1) Found main PCB bad. Check low voltage coming out from power supply. But no voltage coming to EVAP. Motor infreezer. Because main PCB bad. Replace PCB and still PO Error.2) Ordered Power Supply Board. Replaced both boards and still PO ERROR. 3) ORDERED FREEZER FAN MOTOR.Left both boards in refrigerator. And found EVAP. Coil was frosted on top and bottom. Fan was bad. Replace evap. Fanmotor kit in freezer. And working ok. No error.I'm out $565 and wondering if just replacing the fan motor would have solved the problem. Anyone else with the issue, might want to check that first.Good Luck!
