Sub-Zero Ice Maker Repair in South Side, Hazelwood & Homestead, PA

Two different machines share this heading. Inside a full-size Sub-Zero, the ice maker is a module in the freezer fed by a solenoid valve, and it stops when the water supply is weak, the fill tube freezes or the freezer itself runs warm. The standalone undercounter ice makers are separate appliances with their own refrigeration, water circuit and drain; the pump-drain versions add a drain pump that can clog and back water into the bin. On any ice maker, mineral scale from the water supply builds up on the parts that touch water and slows production. Descaling by the maker's procedure comes before any part is condemned, and a slow feed from an old saddle valve or kinked line is ruled out early.

One more point: most Sub-Zero built-ins have two independent refrigeration systems, one per side, each with its own compressor, so the first job is finding which side is at fault.

What we look at first on this pairing: Fill tube frozen in the freezer; Water valve not opening fully; Scale slowing undercounter production; Drain pump clogged and flooding the bin; Bin sensor misreading and stopping production.

That's where we start, not a verdict. The same complaint can come from an inexpensive part or a costly one, which is why the cause is confirmed in your home before any price is given.

A refrigerator in an unheated space works on the edge of its design. In summer it runs constantly; in January it may hardly run at all, and a freezer that depends on the fresh-food thermostat thaws.

Before paying for a repair on a garage unit, check the manual's ambient-temperature range. We'll check it too, and tell you if the location is the actual problem.
