KitchenAid KTRS21KL Refrigerator Service Call

KitchenAid refrigerator

Most common issues on this model

  1. A worn-out gasket, with moisture around the door frame and a compressor that rarely stops
  2. Thermistor drift that leaves the top shelf frozen or the whole cabinet too warm
  3. An inlet valve dripping slowly behind the cabinet where it goes unnoticed
  4. A start relay that fails and keeps a good compressor from starting

Beads of moisture around the door frame are the first sign on a KTRS21KL that the gasket has perished. The refrigerator is a discontinued model, also sold as KTRS21KLSS and KTRS21KLWH, and when the seal loses its spring the compressor never gets a rest. The moisture itself can also stain the frame and the floor beneath it.

We replace a perished gasket without drama, then check the cold control and thermistor, because a drifted sensor can make a cabinet either run warm or freeze the top shelf. A look behind the cabinet reveals whether the inlet valve is weeping, and a meter test of the start relay rules out the compressor circuit. Each step is explained as we go, so you know what is worn and what is fine.

You see the price in writing before any work, and we back the repair with a 30-day workmanship warranty.

KTRS21KLKTRS21KL questions
What does moisture around my KTRS21KL door mean?

Warm room air is getting past a worn gasket and condensing on the cold frame. Replacing the gasket fixes it. We also check the door alignment, since a sagging door can crush the seal.

Is the thermistor in a KTRS21KL easy to replace?

Yes, once the panel covering it is removed. We test its resistance against the temperature, replace it if it reads wrong, and confirm the cabinet settles at the setting afterward.

Why does the KTRS21KL compressor run all the time?

A perished gasket, a drifted sensor or a dirty condenser can each cause it. We check all three in order, because fixing only one often leaves the cabinet working too hard.
