Common fault
Why is my oven not heating properly?
Short answer
Most ovens called dead are still making heat. Just not the amount printed on the dial. Say so when you call Point Loma Sub-Zero Specialists on (858) 375-1585.
The reasoning behind that
Sensors drift as they age, the control takes that reading on trust, and the household experience is uneven browning and a roast that has quietly started needing an extra half hour. Calibration, in other words, rather than a range at the end of its life. No heat whatsoever is usually the cheaper diagnosis: a gas oven whose glow bar lights up beautifully while drawing too little current to open the safety valve, or an electric one with a dead bake element or relay behind it. And when an oven quits the instant a self-clean finishes, look at the door latch before anything else.
How the diagnosis goes
If it is gas and you can see the igniter, watch it before you call. Switch the oven on, look underneath, and time it. A healthy glow bar has the valve open inside about a minute. One that sits there glowing orange for four or five minutes and never lights gas is failing in the classic way, and the reason it fools people is that it looks perfect the entire time. It is drawing too little current to trip the valve, and it will never tell you so. That single observation usually settles the diagnosis before the range gets pulled out of its opening.
In the older Point Loma houses there is a second thing worth thinking about, which is the room rather than the range. Kitchens around Loma Portal and the Wooded Area were laid out when a range was thirty inches wide and ventilation meant opening a window. A professional range has since gone into that space and the venting was solved with whatever the remodel would allow. Heat that cannot leave the room sits around the control housing and the sensor, and neither part enjoys that year after year.
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 fit, and is the work covered afterward?
OEM parts, or an authorized supplier when the factory part is unavailable, and the repair carries a warranty on parts and labor. Cheaper pattern components circulate and we leave them where they are: a non-original fan motor or sensor runs a while and turns up on the same fault list a season later. Proximity to the water sharpens that, because the hardware holding a fan or a connector together is working in salt air. Call Point Loma Sub-Zero Specialists on (858) 375-1585 and ask.
The appliance is still inside its factory warranty. Who should I call?
Call the manufacturer first. Coverage on the sealed system can hinge on who opens the machine, and paying out of pocket for protected work helps nobody. Once the term expires, or the fault falls outside it, the job gets priced whole before a panel moves. Most Sub-Zero equipment here is well past its factory date, some of it having outlived a remodel of the kitchen around it. That is a two-minute call to Point Loma Sub-Zero Specialists on (858) 375-1585.
