Start here
Expect splatter baked onto the sealing surface first. The limit on this page is clear: cleaning and alignment are owner work; a damaged door, a bent frame or a failed interlock is not, and the oven stays off until it is dealt with.
What you observe
- The door needs a push or a lift to latch — A latch or hinge that has worn, which will get worse and eventually stop the oven running at all.
- The door drops or hangs low on one side — A hinge that has worn or a fixing that has loosened.
- Food residue and grease on the seal face around the cavity — The commonest and most correctable cause: debris holds the door off its frame.
- NEAR MISS — the oven runs but does not heat — A door that latches and an oven that runs cold is a heating fault, and that page ranks the causes for it.
The ranking, and why it is this way round
- Splatter baked onto the sealing surface — It is the most common cause of every complaint on this page and the only one that costs nothing to correct: warm soapy water, a soft cloth, and no abrasives. Top of the list, because everything below it is harder to check and less likely to be the answer. This is a brand with a service network behind it, so the ranking assumes parts can be had and focuses on which one is actually at fault.
- Spring tension lost in the door catch — A sticking catch produces the intermittent version: the oven runs sometimes and stops mid-cycle other times, which owners read as an electronic fault. It follows the first because the two produce the same complaint, and this one is the cheaper of the pair to eliminate.
- Hinge pins that have worn oval — It sits here because the diagnosis is visual and immediate — hold the door closed and look along the gap — and because the fault is structural rather than cosmetic. It ranks here because it is genuinely less common, not because it matters less when it happens.
- Door panel damaged, dented or cracked — The door is part of the oven's shielding, and its inner panel and mesh are what keep the energy in the cavity. Any dent, crack or hole in that assembly is a stop-using-it fault, and no amount of cleaning or adjustment changes that. Last, and deliberately so — it should be where a diagnosis ends rather than where it starts.
Check in this order, and why
- Look along the flat face around the cavity opening with a torch — Baked splatter is often invisible head-on and obvious at an angle. Begin with this one; everything after it depends on what you find.
- Open and close the door slowly and listen for the catch engaging — A catch that clicks reluctantly or needs help is on its way out. Next, because it takes the same few minutes and covers the other likely half.
- Close the door and look along the gap at the top and the bottom — A gap that tapers means the door is hanging low or the frame has moved. Third, and the last thing worth doing before the phone comes out.
The checks you can make yourself
- Dry both faces and close the door slowly, watching how it meets the frame — It should pull itself home without a lift or a push.
About 10 min
- Clean the latch area and the catch recess of grease and crumbs — Do this with the oven unplugged; debris in the recess is a common cause of a sticking catch.
Tools: cloth, torchAbout 20 min
- Stop using the oven if the door hangs visibly out of square — A door out of square is a shielding question, not a convenience one.
About 5 min
- STOP here and write down what each check showed — A technician arriving with the cheap causes already eliminated spends the visit fixing rather than repeating your work.
Read this before you start
Safety
Unplug the appliance before touching anything inside the cavity, and keep the outer cabinet closed — the components behind it hold a charge after the power is off. Use no abrasives on the door face or the cavity, and never run the oven with nothing in it.
When this becomes a service call
Book a visit when the latch no longer holds, when the oven stops as the door is nudged, or when the door hangs out of square. Never remove the outer cabinet yourself: the capacitor inside can hold a dangerous charge long after the oven is unplugged.
