Common fault

Why does frost keep building up in my freezer?

Short answer

Frost that returns after you clear it means the defrost cycle is not completing. The usual causes are a failed defrost heater, a thermistor that has drifted, or a door seal that has lost its magnetic pull and is letting humid air in. The coil then insulates itself with ice and cooling degrades a little more each day — which is why owners describe it as gradually getting worse rather than breaking.

If that matches what your appliance is doing, say so when you call — it tells us which parts to bring, and most of these are finished in one visit.

When our Sub-Zero refrigerator broke down during the holiday, their service was a lifeline. A technician was dispatched quickly to Loma Portal and resolved the issue the same day. Genuine 24/7 support that truly helps in emergencies.

Our wine cooler wasn’t maintaining temperature. They understood the urgency, arrived the same day, and swiftly replaced a faulty sensor from the technician’s truck. Exceptional, efficient service near Sunset Cliffs.
