Common fault
Why is my oven not heating properly?
Short answer
An oven the cook has given up on is usually still working. It heats faithfully to the wrong number, because the sensor has drifted and the control believes it. Temecula Valley Sub-Zero Appliance Repair Specialists takes those calls on (858) 465-4117.
Why we start there
No heat at all is simpler: on gas a glow-bar igniter too weak to open the valve, on electric the bake element.
What happens next
Drift announces itself as browning that is wrong on one side of the tray, and as a roast that has quietly needed an extra half hour for a year, rather than as an oven that never comes up to heat. Calibration is the fault most worth catching, because it never announces itself. A Wolf or Viking oven that has drifted well under its setpoint still lights, still runs, still smells like a working oven, and simply turns out food that is wrong in a way the cook keeps compensating for without ever calling it a fault. It is settled by measurement rather than argument: a calibrated probe at rack level read against the sensor's own resistance table. The fix is usually the sensor or an offset in the control, not a range at the end of its life. People replace entire ranges over this, and in these kitchens that is a very expensive way to correct a small number.
No heat at all splits cleanly by fuel. On gas we measure igniter current draw under load rather than judging it by how brightly it glows, because a weak glow-bar looks perfectly healthy and still will not open the valve, and it fails gradually, so the oven takes longer and longer to come up before it stops altogether. On electric it is the bake element, its relay, or a connection at the back of the cavity that has cooked itself loose. And if the oven went dead the instant a self-clean finished, look at the door first: a latch that never released is a far more common answer than a failed board, and it costs a fraction of one.
If that matches what yours is doing, say so when you call — it decides which parts come on the van.

Questions
Frequently asked questions
What parts do you use, and what happens to my factory warranty?
Genuine parts, fitted after the repair has been quoted and agreed. Temecula Valley Sub-Zero Appliance Repair Specialists stays out of the pattern-parts market: a non-original evaporator fan will usually run, and usually be back on the fault list inside a season. Still under factory warranty? Call the manufacturer first, then (858) 465-4117.
Our built-in is getting on in years. Is repairing it still the sensible call?
Repair wins nearly every time here, and the cabinetry is as much of the reason as the appliance. A built-in is sized to an opening that was framed once and never meant to change. Most jobs end in ordinary parts, and Temecula Valley Sub-Zero Appliance Repair Specialists prices them before fitting: (858) 465-4117.
