The short answer
On EM models a fair number of no-heat calls are the appliance doing exactly what it was asked. The roster spans more than one control generation, the programmes are not presented the same way across them, and a level or a mode set by accident produces an appliance that runs, counts down and warms nothing. Rule the panel out before you rule the appliance in.
What the panel is reporting
- The display counts down normally and the food is cold — A programme is running. Whether it is a heating programme is the question.
- The appliance has never heated since it was installed — That history points at a mode rather than at a failure.
- It heats weakly rather than not at all — A power level is a far likelier explanation than a partial failure of the heating side.
- A word or symbol on the display you do not recognise — On the builds that show mode indicators this is the whole answer, once it is looked up.
- It heats on one programme and not on another — Conclusive: an appliance that can heat at all is not suffering a heating-side failure.
Ranked causes on this roster
- A demonstration or display mode — It runs the panel and the turntable and disables the heat deliberately. It leads this list because it explains the most confusing version of the complaint — an appliance that has never worked — and because clearing it costs nothing.
- The power level — Left low after a defrost, or set by a key press nobody remembers. The appliance heats, just not at the rate anybody expects, and owners reasonably describe that as not heating.
- The programme that was selected — Weight-based and timer programmes behave differently, and on some builds of this roster a timer will run the display with no heat at all.
- The door circuit — Once the panel is cleared, this is the leading hardware candidate: the appliance can run while the part of the circuit that enables the heat is never made up.
- The heating side of the appliance — Last, and only after the panel has been cleared and the door eliminated. It is the one item here that needs a technician rather than a minute.
Clear the panel, then test properly
- Clear the appliance to a known state and run a short heat on full power with a mug of water — Always test with water in the cavity, never empty. This single test answers most of this page.
- Check the power level explicitly rather than assuming it — On several builds of this roster the level is not shown once a programme is running.
- Try a different programme — An appliance that heats on any programme is an appliance whose heating side works.
- Look up any unfamiliar indicator on the display — Mode indicators differ across the control generations here, and one of them disables the heat by design.
- Work the door deliberately, then retry — It is the free end of the hardware branch, and it goes before the appliance is opened by anybody.
Before you open anything
Safety
Test with water, never with an empty cavity. Nothing on this page needs a panel removed, and the panel is where the danger is: unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Stop using the appliance if you see arcing in the cavity or smell burning during a run.
When to call a technician
Clearing modes, checking the level, trying another programme and working the door are all owner work, and on this roster they account for a large share of no-heat calls. What is not owner work is anything behind a panel. Call once the appliance has been tested from a known state, with water, on full power, and the water is still cold.
