Refrigerator not cooling: what it usually is

When customers reported “not cooling” on a refrigerator, AssistAnt technicians most often found: sealed system (compressor / refrigerant) (57%), not cooling (fan, defrost or controls) (32%) and ice maker (18%), across 56 diagnosed repairs since June 2026.

Finished on the first visit in 54% of the 48 repairs that recorded it; the rest needed a part ordered or a second trip.

These are repair reports, not a reliability ranking: we see more of the brands more people own, and many of these jobs came through home-warranty companies. Counts are what the technician found; one job can show more than one problem.
