The short answer
On the AN family an oven that will not reach temperature is usually a control or a sensor problem, and an oven that will not heat at all is usually an element or its supply.
What you observe on these models
- The oven heats but never reaches the set temperature — Something is telling the control it is hotter than it is, or the heat is escaping as fast as it is made.
- No heat at all, with the control lit and the fan running — The appliance has power and a control. What it does not have is an element circuit.
- One element works and the other does not — Grill without bake or bake without grill is an element or a selector fault, not a thermostat one.
- NEAR MISS - the oven heats but the breaker trips — A trip under load is an electrical-safety complaint and belongs on that page, not this one.
Causes, most likely first on this family
- Bake or grill element open circuit — First on this family for an oven that makes no heat at all. Elements fail where they pass through the cavity wall, and a visible blister or a break confirms it without any measurement, and because the family is one platform whose model numbers share a prefix, the same fault turns up across the models listed above.
- Temperature sensor or thermostat out of calibration — Second, and first for an oven that heats but underperforms. A sensor reading high satisfies the control early, and the oven then sits below its set point for the whole cook.
- Door seal and door alignment losing heat as fast as it is made — Third. A gradual decline in performance with no component failure is usually the door, and it is worth ruling out before any part is bought.
- Selector switch, control board or supply — Last. One function working and another not points at the selector, and an oven that is dead across the board points at the supply rather than at any of the parts above it.
Check in this order, and why this family dictates it
- Decide first whether there is no heat or not enough heat — They are different faults with different parts, and everything after this depends on the answer.
- Watch the element through the cycle with the light on — Second: an element that never glows, or glows in patches, has answered the question for the no-heat case.
- Put an oven thermometer in the centre and compare with the setting — Third, and it is how the not-enough-heat case is proven rather than argued. A consistent offset points at the sensor; wild swings point elsewhere.
- Paper-test the door seal all the way round — Last of the owner checks, and it is the one that explains a slow decline that no part replacement has fixed.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, and an oven circuit stays live at the terminal block even when the appliance looks dead. Never defeat the door lock or the door switch to keep an element running with the door open. If you smell gas: do not switch anything on or off, leave the building, and call the gas utility from outside.

When to call a technician
Call when an element is visibly broken or blistered, when an oven thermometer shows a consistent offset from the setting, when one function works and another does not, or when the appliance is dead with a known-good supply.
