The short answer
An oven that will not heat, or that never reaches the temperature it is set to, usually has a fault in the heat source or in the sensor that tells the control what is happening. On a compact cabinet the ranking below starts with the things an owner can genuinely verify and then stops at a clear line, because oven work involves either a large electrical load or a gas burner.
What you observe
- The oven is completely cold with the display working — No heat being produced at all, which points at the element, the igniter or the supply.
- It heats but never reaches the set temperature — Sensor, calibration or a door that is not sealing.
- NEAR MISS: the display is dark and nothing responds — That is a supply or control fault and belongs on a different page.
Causes, most likely first on this appliance
- The oven is in a mode that prevents heating — A sabbath mode, a demonstration mode, a delay start or a self-clean lock left engaged. Ranked first on Danby: a compact oven has a thin cavity, a small door and electronics sitting close to the heat, so the seal and the heat path dominate everything behind them, and this line spans bar cabinets to apartment units, all of them designed to go where a full-size appliance would not.
- Half the supply missing on an electric oven — An electric oven needs both legs of its circuit. Ranked second: it ranks here because it is common enough to be worth checking, but only once the free checks above are clean.
- A failed bake or broil element on an electric oven — An element that has opened stops producing heat, and it often shows a visible break or blister. Ranked third: it is in the middle of the list because it is cheap to rule out and expensive to assume.
- The oven temperature sensor — The probe in the cavity that tells the control the temperature. Ranked last: it is last because on an appliance this size the major components outlive everything around them, and replacing one often costs more than the appliance is worth.
Check in this order, and why
- Clear everything and set a plain bake at a normal temperature — An oven that heats on a clean simple setting was in a mode rather than broken.
- Note whether nothing at all heats while the display is normal — A fully working panel with no heat anywhere points at the supply rather than at any one part.
- Look at each element while the oven preheats — An element that does not glow at all, or one with a visible break, names the fault without any tools.
What an owner can safely check
- Cancel every programme and set a plain bake cycle — Clear any delay, timer or special mode, then select ordinary bake at a middling temperature and give it time to preheat.
About 15 min
- Preheat and look at each element in turn through the door — Watch which elements glow.
About 20 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Switch the oven off at its breaker before removing any panel or touching anything inside the cavity beyond a thermometer, and keep it off while your hands are inside. Let the cavity cool fully before reaching into it. On a gas oven, do not disturb the burner, the igniter or any gas fitting, and if you smell gas at any point: do not switch anything on or off, leave the building, and call the gas utility or your emergency services number from outside. Do not look for the leak yourself.
When to call a technician
Call once the mode, the elements, the door seal and the calibration have been checked and the oven still will not heat or will not reach temperature. Everything left, on both electric and gas, involves either a large-current connection or a gas valve, and neither has an owner version.
