Sub-Zero Freezer Repair in the Bay Area
Freezer trouble is rarely “just the freezer.” On Sub-Zero, frost build-up, soft ice cream or a unit that won’t hold temperature usually points to the defrost system, an evaporator fan, or a tired door gasket. We test the whole chain and fix the cause.

Common freezer repair problems
If your unit is doing any of these, we can almost certainly help — usually the same day.
Not freezing / too warm
Food softening, ice melting, temperature creeping up above set point.
Frost & ice build-up
Heavy frost on walls or coils — almost always a defrost heater, sensor or timer fault.
Over-freezing
Frozen-solid produce and frost where it shouldn’t be, from a stuck damper or control issue.
Drawer & seal problems
Drawers that won’t glide or seal, letting humidity and frost in.
Loud or cyclical noise
Buzzing, knocking or fan noise that signals a failing motor or iced-up evaporator.
Drain & leak issues
A frozen defrost drain pushing water into the cabinet or onto the floor.

What Bay Area homeowners say
Our built-in Sub-Zero stopped cooling overnight. They came the same day, found a failed evaporator fan, and had it cold again before dinner. Clear pricing, no drama.
I thought I needed a whole new fridge. Turned out to be a control board — they diagnosed it properly instead of throwing parts at it. Saved me thousands.
Our Wolf range wouldn’t light. The tech replaced the igniter and cleaned up a burner the same visit. Knew the appliance inside out.
Wine fridge was swinging in temperature and I have bottles I actually care about. They recalibrated the zones and replaced a sensor. Rock-steady since.
The ice maker had quit completely. They traced it to the water valve, not the whole module like another company wanted to replace. Honest and fast.
Replaced the door gaskets and dialed in the temps on our Sub-Zero column. Food’s fresher, the bills dropped, and the tech left the kitchen spotless.
