Ice maker stopped working? We repair frozen water lines, inlet valves, and ice maker modules. Same-day service, 90-day warranty. Average repair cost: $100–$350. Some causes are DIY-fixable — see below.
San Jose's moderately hard water from blended local and imported sources at 280 ppm TDS is one of the leading contributors to ice maker failures across the South Bay. Dissolved minerals — primarily calcium and magnesium — gradually deposit inside the water inlet valve, reducing the orifice diameter until water flow drops below the minimum required for the ice maker's fill cycle. This process accelerates in San Jose's hot, dry climate where higher water consumption means the inlet valve processes more total volume per year. Many 1960s ranch homes in Willow Glen and Cambrian have original copper supply lines that develop pinhole leaks at solder joints, reducing pressure to the ice maker. Tech-savvy San Jose households frequently install premium refrigerators with through-the-door ice and water dispensers, adding complexity with dual-valve systems and electronic flow sensors that are sensitive to mineral scale. With 65 competing repair services in Santa Clara County, finding one that stocks common Samsung and LG ice maker parts for same-day service matters.
San Jose's blended water at 280 ppm TDS deposits mineral scale inside water inlet valves and ice maker fill tubes faster than in soft-water East Bay cities. The hot, dry climate increases household water consumption, processing more total volume through the inlet valve annually and accelerating scale accumulation. Many 1960s homes have aging copper supply lines with deteriorating solder joints that reduce water pressure below ice maker minimums. Premium through-the-door dispensers with electronic flow sensors are especially sensitive to flow restriction from mineral buildup.

Normal wear on internal parts is the leading cause of ice maker ice maker not working issues. Regular use over 5-10 years gradually degrades moving parts and seals.
Cost: $100–$200 | Time: 60-90 minutes
Control board malfunctions, faulty sensors, or wiring issues can cause ice maker not working symptoms. Power surges and age-related degradation are typical triggers.
Cost: $120–$240 | Time: 45-75 minutes
Debris, mineral deposits, or foreign objects can restrict normal operation. This is often preventable with regular maintenance.

Ice maker repairs in the Bay Area run $100-$350. San Jose's hard water makes inlet valve replacement the most frequent ice maker repair in the South Bay, typically costing $150-$250 installed. Installing an inline water filter ahead of the refrigerator extends inlet valve life significantly in San Jose's mineral-heavy water.
In San Jose, wide day-night temperature swings (30f+ delta) stress thermal expansion joints, thermostat cycling, and sealed-system pressures. This can affect your appliance's fill tube: cold ambient temperatures freeze residual water in the fill tube, blocking water flow and stopping ice production entirely If ice production stops in cold weather, check the fill tube for ice blockage; a hair dryer on low can thaw it
