A solid slab on the back wall behind the shelves, with the rest of the cabinet fairly clear, is the defrost circuit. They are different repairs and the pattern tells you which before anybody opens anything. ### What it usually means, by the company that built it Kenmore manufactures nothing, so the same behavior points at different things depending on who made the appliance. The three digits before the period on the rating plate are what tells them apart. - **253 Frigidaire** — Standalone Frigidaire-built freezers, upright and chest. Chest units have no defrost circuit at all and the scraper came in the box. - **106 Whirlpool** — Whirlpool-built uprights with automatic defrost, where the heater and its thermostat are the usual finding. ### Frost is water that got in Every scrap of ice inside a freezer arrived as humidity, and in South Florida there is a great deal of humidity to arrive. That is why frost problems here run ahead of the schedule the manual assumes, and why a door seal on a garage freezer is worth more attention than one on a kitchen refrigerator. ### Why a defrost repair starts with the door Because a defrost circuit that failed under normal load and one that failed while working twice as hard are two different stories, and only one of them is finished when the heater is replaced. We check the seal in the same visit for that reason. It is a manual-defrost cabinet Chest freezers and some older uprights have no defrost circuit. The frost is expected and defrosting it once or twice a year is the maintenance. The door seal Warm humid air in, frost out. Here that happens faster than the manual expects.

Does the door close by itself from an inch open If not, level and hinge come before anything electrical. Is it in a garage or a porch Every door opening in unconditioned air brings in far more moisture than one in a kitchen. More ice than there should be, and it keeps coming back What it usually means On a chest freezer this is normal On an automatic-defrost cabinet it is not Where the frost sits tells you which problem it is Look at where the frost is An even light coating over everything, worst near the door, is air getting in — a seal, or a door that is not closing square.
