Common fault
Why is my oven not heating properly?
Short answer
Most ovens described as not heating are heating, just not to the number on the dial or not evenly across the cavity.
What is actually going on
On a convection oven the complaint is frequently the convection fan or its ring element rather than the bake element: food browns on the side nearest the fan, the third rack never cooks, and everything runs long while the display insists the oven is at temperature. Even browning with long cooking times throughout is calibration, where the oven sensor has drifted and the control is faithfully obeying it. A genuine no-heat fault is usually cheaper than either. On gas the glow-bar igniter is the usual answer: it goes on glowing bright orange while the current through it falls under the threshold that lets the safety valve open at all. On a dual-fuel range the electric half fails at the bake element, or at the relay behind it.
What we check, and in what order
Bake, broil and convect are three different circuits sharing one cavity, so they get tested separately. An oven that bakes correctly and browns unevenly on convection has a fan or a ring element fault, not a sensor. An oven that reaches temperature on bake but takes far too long has either a weak element or a door that is no longer sealing, and on a wall oven the door gasket and the hinge springs are as much a temperature part as anything electrical. We run each mode and record what the cavity actually does rather than trusting the setpoint, because the display reports what the control believes and what the control believes is precisely what is in question.
On gas ovens the glow-bar igniter is the part we replace most often and the one most commonly misread. It is a heater and a current sensor at the same time: gas only flows once the igniter draws enough current for the safety valve to open. As it ages that draw falls off, so the oven is slow to light, then unreliable about lighting, then done, all while glowing bright orange and looking perfectly healthy. That is why valves and control boards get replaced over it. The test is a clamp meter on the igniter leg, not a look at the color.
If that matches what yours is doing, say so when you call — it decides which parts come on the van.
Reviews
Long drive, gate and keypad out in Rancho Santa Fe, and they asked for the code and the model number when I booked rather than calling from the end of the driveway. The garage refrigerator was the dead one, and he pulled the grille on the Viking outside while he was here.

Drawers in the island were rattling and kicking on and off every few minutes. Downtown condo, everything crammed in tight, and the condenser under there had never been cleaned. Grille off, coil done, fan checked. Fast, tidy, explained everything.

Questions
Frequently asked questions
We are at the far end of the county, out toward Fallbrook or Valley Center. Does that change anything?
It changes how much the phone call is worth. A second trip out the 76 or up the 15 costs a day, so we ask more before setting off: model and serial number, which compartment is warm, whether the freezer is still hard frozen, any display code, and whether there is a gate or keypad at the drive. Same-day or next-day still applies.
