The short answer
On the AN family an electrical complaint - a trip, a tingle, a hot smell - points at the connection at the back of the appliance far more often than at anything inside it.
What you observe on these models
- The breaker trips when the oven calls for heat — The heating stage is the heavy part of the load, so a marginal connection or a failing element shows there and nowhere else.
- A hot or scorched smell from behind or below the appliance — At the terminal block that is a loose connection heating under load. Isolate before investigating.
- A tingle from the door, the frame or a pan on the hob — Stop and isolate at the breaker. This is an earth-path fault and it is not something to test by touching again.
- NEAR MISS - the oven simply does not heat and nothing trips — That is a heating fault rather than an electrical-safety one, and the checks are different.
Causes, most likely first on this family
- Terminal block or supply connection loose or wrongly made — First on this family. The block takes the full load of the appliance, and a screw that was not properly tightened at installation heats every time the element runs until something gives, and because the family is one platform whose model numbers share a prefix, the same fault turns up across the models listed above.
- Heating element shorting to its sheath or to the cavity — Second. An element that has blistered or sagged into contact trips protection repeatably at the heat stage, which is a distinctly different pattern from the intermittent trips a loose connection gives.
- Moisture and grease tracking around the door switch, lamp or wiring — Third. Cleaning water in the cavity vents, in the lamp housing or across a connector produces intermittent trips that come and go with the humidity of what is being cooked.
- Circuit, breaker and protection device themselves — Last as a cause but first as a question for an electrician: a circuit shared with other heavy loads, or an ageing protective device, produces trips that no oven repair will cure.
Check in this order, and why this family dictates it
- Isolate at the breaker before doing anything else — Everything on this page is done with the appliance dead. A tingle or a burning smell is not something to investigate live.
- Note exactly when it trips: at switch-on, at heat, or at random — Second, and it is the single most valuable piece of information you can give a technician. The timing separates connection faults from element faults.
- Look for discolouration or melted plastic at the connection point — Third, with the power off: heat damage at the block is visible and it is conclusive.
- Stop at the point where a meter is needed — Last: element and earth-path measurements need isolation, a meter and someone who knows what the readings mean, and that is where owner work ends.
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 immediately for any tingle from the appliance, for any burning smell, for heat damage at the terminal block, and for a breaker that trips more than once. Call an electrician rather than an appliance technician when the damage is at the outlet or in the circuit, because replacing the oven will not fix the wiring feeding it.
