The short answer
On TF models a running appliance that produces no heat is a door question more often than owners expect. The latch arrangement common to this roster does two things: it lets the appliance run, and it separately enables the part of the circuit that does the heating. A chain that is marginal can do the first and not the second, which is precisely the complaint on this page.
The signature on this platform
- Everything runs and nothing gets warm — Lamp, turntable, fan and countdown all normal, food cold.
- Holding the door firmly shut makes it heat — Close to conclusive on this platform, and a test rather than a way to use the appliance.
- It heats sometimes and not others, with no pattern — Intermittent behaviour in the chain, and the stage at which to book.
- A hook looks rounded or sits differently from its pair — Visible with the door open and usually the underlying cause.
The chain, and what it enables
- A door chain made up only partly — Enough contact to let the cycle run, not enough to enable the heat. It leads because it is the mechanism behind the exact symptom on this page and because the platform shares one latch arrangement across the roster.
- Worn latch hooks — The cause upstream of it. Worn hooks close the door convincingly while holding the contacts short of where they belong, and they are what an owner can actually see.
- A switch in the pack that has gone intermittent — It produces the heats-sometimes version of the complaint, and it is the last stage at which the repair is simple.
- The settings, before any of the above — A low power level or a timer programme produces the same description from a healthy appliance, and it costs nothing to rule out.
- The heating side itself — Last on this platform rather than first, because the door explains this symptom here more often than the expensive parts do.
Test the heat, then read the door
- Run a mug of water on full power for a short time — Water, never an empty cavity. It converts an impression into a test.
- Repeat it while holding the door firmly shut — A difference between the two runs points straight at the door chain. Do it once, as a test.
- Check the power level and the programme first — They produce the same complaint from an appliance with nothing wrong with it.
- Compare the hooks with the door open — Uneven wear between them is the visible form of the cause above.
- Ask how long the door has been awkward — On this platform the history is part of the evidence and it costs nothing to recall.
Before you open anything
Safety
Holding a door shut is a diagnostic test performed once, not a way to keep cooking. Do not interfere with the latch, the hooks or the contacts behind them to make the heat come back — the chain being fully made up is what guarantees the appliance cannot heat with a door it cannot confirm. Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off.
When to call a technician
Testing with water, checking the settings and looking at the hooks are owner work. The switch pack is not: it is behind a panel, the parts are matched as a set, and a half repair on this platform produces an appliance that fails dead rather than gradually. Call as soon as the held-door test makes a difference, or as soon as a hook looks unlike its pair.
