Most likely causes, in the order we check them
| Cause | What you see | Fix |
|---|---|---|
| Weak oven igniter (gas) | Glows orange but never opens the gas valve. The classic slow death: preheat takes longer each week until the oven stops heating. | Us |
| Failed bake or broil element (electric) | One works, the other does not. Sometimes visible as a break or blister in the element. | Us |
| Oven sensor drift | Oven heats but sits 25 to 50 degrees off. Baking suffers first, roasting later. Display still shows the number you set. | Us |
| Door not sealing | Hinge springs tired or gasket flattened. Heat escapes, the oven chases temperature and never settles. | You or us |
| Convection fan not turning | On convection settings the oven browns unevenly and takes longer. The fan or its relay. | Us |
| Control board | Display works but nothing heats, or settings do not hold. Checked last, because the cheaper causes are the common ones. | Us |
What you can safely check yourself
- The clock and mode. Confirm the oven is not in a delayed start, sabbath or self-clean mode. It happens more often than people admit.
- The door. Close it and look for a gap at the top corners. Put a sheet of paper in the gap and pull. If it slides out freely, the seal is done.
- An oven thermometer. Set 350, wait 20 minutes, read the thermometer. A 25 degree gap or more is the sensor, not your imagination.
- The breaker. On electric and dual-fuel, a half-tripped double breaker leaves the display alive and the elements dead. Reset it once.
Not heating at all, and heating wrong: different faults
If the oven never gets warm, the fault is on the heat side: igniter, element, or the board that switches them. If the oven heats but food comes out wrong, the fault is on the control side: sensor, door, fan.
We ask which of the two you have before the visit, because they need different parts on the van.
Why a Viking igniter fails slowly rather than suddenly
A gas oven igniter has to draw enough current to open the safety valve. As it ages it still glows, but draws less, so the valve opens later and later. That is why preheat creeps from ten minutes to twenty-five, and then one day the oven never lights. A glowing igniter does not mean a working igniter.

Questions we get asked
The igniter glows. Does that not mean it works?
No. Glowing only means it is drawing some current. The test is whether it draws enough to open the gas valve, and that is measured, not seen.
Can a drifting oven be recalibrated instead of repaired?
Small offsets can be calibrated in the control. A sensor that has failed will not hold calibration, and we will tell you which one you have.
How long does the repair take?
Igniters, elements and sensors are usually one visit. Boards for older models are sometimes ordered, and you get the part name and date before we leave.
Is it worth repairing an oven that is fifteen years old?
On a Viking, usually yes. The cabinet and burners outlive the parts that fail, and those parts are still made.
