The short answer
What you are seeing on a Summit oven most often comes back to an element failing to earth, with a failed relay, board or internal wiring behind it. Work the order below rather than the price list: the cheap causes here are also the common ones.
What you are seeing
- The breaker trips when the oven or the grill comes on — The fault appears with load, which is the most informative thing about it.
- A burning smell that is not food — Overheating insulation or a connection. Stop and isolate the oven.
- NEAR MISS: a smell on the first few uses of a new oven — Normal: the protective coating on new elements burns off.
What it usually turns out to be, in order
- An element failing to earth — An element that has blistered arcs to its sheath as it heats, which trips the circuit at the exact moment it switches on. First on Summit because heat is made by one circuit and protected by another, and either can stop it.
- A failed relay, board or internal wiring — The fault is inside the oven and nothing about the circuit or the elements explains it. Second, because a board decides the behaviour rather than a switch, so a control fault reads as a machine declining to act.
- A loose or scorched terminal connection — A connection carrying a heavy load warms, loosens and warms further, and that loop ends in scorching or worse. Third: nothing else can be judged until the machine is genuinely receiving power.
- Moisture from cleaning or a spill in the wiring — Water that has run into a wiring channel after a heavy clean trips the circuit until everything dries out. Last, which is why it is checked last: a seal fails gradually, so the symptom arrives long after the seal stopped being good.
The order to work in
- Note whether it trips on the oven, the grill or both — Which one trips names which element, and that is most of the diagnosis.
- Once the elements, the terminals and the circuit are clean, the fault is internal — Stop using the oven.
- Look for discolouration or a smell around the terminal block, without opening it — Scorching means stop using the oven now.
What an owner can safely check
- Note exactly which function trips the breaker, then stop using that function — Do not keep resetting to see: each arc damages more of the element and the wiring.
About 15 min
- With the breaker off, look for scorching or a burnt smell at the back, but do not open the terminal block — An oven terminal block is a heavy-current connection and is not an owner adjustment.
Tools: a torchAbout 15 min
- Leave the oven off and open to dry for a day or two after a heavy clean or a spill — Then test on a low setting rather than straight to full.
About 30 min
- STOP HERE: switch the oven off at the breaker and leave it off. Internal wiring is not an owner repair — A service call, and a prompt one.
Read this before you start
Safety
Switch the oven off at its breaker before removing any panel, and let the cavity cool completely first. A capacitor can hold a charge after the power is off. If you smell gas: do not switch anything on or off, leave the building, and call the gas utility or 911 from outside. Do not look for the leak yourself. Never defeat a door lock to open a cavity mid-clean, and never line the floor of an oven with foil.
Where the owner fix ends
Stop using the oven and call for any burning smell that is not food, visible scorching at the terminal block, or a breaker that trips repeatedly. Do not keep resetting a breaker to see whether it holds: each arc does more damage. If you smell gas, leave the building and call the gas utility or 911 from outside without switching anything on or off.
