Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: NQ70T5511D*
What that covers: Samsung microwave combination wall oven — no cooktop at all; every burner symptom is out of scope for this unit.
Not applicable to this hardware: This Samsung NQ70T5511 microwave combination wall oven does not have the hardware for: gas burner clicks but will not light; electric or radiant burner will not heat correctly; induction zone does not detect the pan. Those symptoms have no page here for this model rather than a page that guesses.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Type — WALL OVEN (no cooktop at all): This is a built-in WALL OVEN, not a range — it has NO cooktop or burners, so any cooktop/burner symptom does not apply to it. It is an oven-only appliance installed in a cabinet, paired with a separate cooktop elsewhere.
Oven — electric: An electric oven with convection and (on many) a combination microwave or Flex Duo split. No-heat is the bake/broil element or control; some are microwave-combo, in which case a 'not heating' can be the microwave vs the oven element — identify which mode.
Self-clean & features: Steam/high-heat self-clean (door locks, some smoke normal), Air Fry on some, SmartThings Wi-Fi. Being built-in, its power is a dedicated circuit — a dead oven is often that breaker.

Exact questions

Questions that only have an answer for the Samsung NQ70T5511 microwave combination wall oven

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

Which burner controls what on my Samsung NQ70T5511?+

None — this is a wall oven, not a range, so it has no burners or cooktop. It is an oven-only unit built into a cabinet, and your cooktop is a separate appliance. So cooktop and burner troubleshooting does not apply here; for the oven itself, no-heat points to the bake/broil element or control, and a completely dead unit is usually its dedicated circuit breaker.
