It's one of our most common calls, and one of the most cheerful to resolve: the refrigerator made perfect ice for years, someone dutifully changed the water filter — responsible! — and within a day the ice maker went on strike. Tiny cubes, no cubes, a dispenser that spits and coughs. The instinct is "the new filter broke something." The truth is usually simpler: the filter change introduced air, and nobody evicted it.
The purge nobody does
Every cartridge swap fills the housing and lines with air, and air is where good ice goes to die: the maker meters fill by time, so a half-air fill makes half-size, hollow cubes, and an air-locked line can stall flow entirely. The fix is in every manual and skipped by everyone: purge two to three gallons through the water dispenser after the swap — run it in one-minute pulls until the stream flows smooth and silent — then discard the first two or three ice harvests. Most "broken since the filter change" calls end right there, at zero parts.
Fit: a quarter-turn from working
Modern cartridges seat with a firm push and a definite quarter-turn stop — and a filter that's almost seated engages its bypass poorly, strangling flow. Pull it and re-seat until it locks decisively. And check the ice maker's own switch while you're there: on plenty of models the shut-off arm or power toggle gets nudged during the wrestling match, and the "failure" is an off switch.
The wrong-filter economy
Bargain cartridges are the false economy of this story: loose tolerances leak at the head, flow restrictions starve the maker, and around here they meet their match fast — well-water sediment out toward Rochester and Rainier eats cheap media in weeks. OEM or certified-equivalent, especially on rural water, is the one place we push brand names without apology.
If it's still sulking
Purged, re-seated, switched on — and still no ice after 24 hours? Now it's a real diagnosis: fill tube frozen from the earlier starved fills, a valve that chose this week to retire, or a filter head o-ring nicked during the swap.
