KitchenAid KSSC42QK Refrigerator Diagnosis
Frozen lettuce on the top shelf, or milk that never gets quite cold, is a typical KSSC42QK story. The cold control or thermistor drifts over the years, and the cabinet follows the wrong number. We read the actual air temperature and compare it with the control’s target, because a reading that disagrees with a thermometer settles the question.
The other repeat finds are quieter. An inlet valve that weeps leaves a puddle behind the cabinet that nobody sees for months. A start relay that fails will stop a compressor that is mechanically fine. And after many years of service, the control board may simply stop honoring what you set.
We work from the simple tests toward the expensive ones, and we show you the readings. If the label reads KSSC42QKS, it is this same model. You get a written price first, and workmanship is covered for 30 days.
A drifting cold control or thermistor often causes exactly that. We measure the cabinet air, compare it with the target, and replace the sensing part if the two numbers disagree.
We ease the refrigerator out as far as the water line allows, inspect the valve and fittings, and check the floor and wall base for staining, which shows how long the weeping has gone on.
If the compressor windings test sound, yes. We replace the relay and overload as a pair when needed, then watch a full start-up to be sure the compressor runs steadily.
