La Cornue in Union City
La Cornue in Union City kitchens.
Union City's La Cornue ranges sit almost entirely in the hillside homes east of Mission Boulevard, up against the Fremont border, where the larger custom lots gave remodeling owners room to design a kitchen around a serious range. It is a short list of ranges, and we likely already know the models on it: mostly CornuFe 110s, one or two all-gas Chateau installs.
What matters for a Union City owner is that the brand experience does not have to be local. We run this corridor constantly between Fremont, Hayward, and Newark, and the La Cornue-specific knowledge rides along: how the ignition pack is laid out, what the oven controls should read at each set point, which door hardware wears first, and which parts wait on a shipment from France.
You get a $75 diagnostic waived with repair, a written quote before any parts order, a one year warranty on the work, and scheduling 7 days a week.
Common repairs we do
What we close on the truck.
- Oven temperature drifting after years of service. A range that baked true for a decade and now runs hot has a control drifting, gas thermostatic valve on the Chateau or electric thermostat on the CornuFe. I chart the cavity against a calibrated probe through full cycles and correct the control side, then leave you the before and after numbers.
- Electrodes shorting through cracked ceramic. Hairline cracks in the electrode insulators bleed spark to the burner body, so you hear clicking but see no arc at the tip. The cracks hide under residue and get missed. I inspect every position under good light, replace the failed electrodes, and confirm crisp light-off at each burner.
- Oven door seal worn on the latch side. Right-handed cooks work the door from one side and the gasket wears asymmetrically, leaking heat along the latch edge years before the rest fails. I replace the full gasket, square the door on its hinges, and check compression around the entire frame rather than just the obvious edge.

FAQ
La Cornue in Union City questions, answered.
-
How long from San Ramon to Union City?
About 30 minutes, either down 680 and across on 84 or along the 238 corridor through Hayward. Union City sits in the middle of our Fremont, Hayward, and Newark routing, so we are in the area most days and can usually offer a slot quickly. -
Can a regular appliance tech handle a La Cornue if you are booked?
Mechanically some faults are universal, but the settings are not. I have re-done work where a generic repair got the burner lighting and left the simmer calibration and door alignment wrong. If we are booked, my honest advice is to wait the extra day or two rather than pay twice. -
What does a written quote from you include?
The specific failed component and the measurement that identified it, the part source and lead time, labor, and the total. The $75 diagnostic comes off the bill when you approve the work, and the repair is covered for one year after.
