Factory-Authorized: Sub-Zero · Wolf · Cove
A cold oven the night you're hosting is more than an inconvenience. We repair high-end ranges, ovens, and cooktops across the North Bay — most the same day — with genuine parts and a price you approve first.
Advance Appliance Services repairs ranges, ovens, and cooktops across Sonoma, Marin, and Napa counties, and has since 2006. We service more than 20 brands — including Wolf, which we're factory-authorized for — from gas and dual-fuel ranges to induction cooktops and built-in wall ovens. Our trucks carry genuine parts, so most repairs are completed the same day, with a written estimate before any work begins.
The problems we see most across every brand. If yours isn't here, call us — we've almost certainly fixed it before.
A worn igniter or dirty burner cap is the usual cause. We restore a clean, reliable light.
Igniters, bake elements, and sensors all cause it. We find which and fix it right.
Ovens drift over time. We test and recalibrate so what you set is what you get.
Induction has its own coils and boards. We diagnose the electronics precisely.
Blocked ports or a failing gas valve starve the burner. We clean and correct the flame.
Latch motors and thermal cut-offs are the common cause. We get the cycle working again.
A failing fan motor throws off even baking. We replace it and restore true convection.
Control-board faults throw codes and blank screens. We read them right and repair the cause.
Not every range is a Wolf — but every range deserves a specialist. We bring factory training to the brand that demands it, and genuine-parts care to all the others.
For Wolf, we're factory-trained and authorized on sealed burners and dual-fuel ovens. See our Wolf range & oven repair page.
Ilve, Bluestar, Lacanche and more — we install authentic components, not aftermarket substitutes.
Our vans carry common cooking parts, so we finish most repairs the same day we diagnose them.
