The short answer
On the ACR oven this symptom is usually the bake element, the part that does the work and the part that fails visibly, which is why it leads on an electric range of this kind. The ACR family splits across trim and finish suffixes rather than across different machinery, so the order below holds for every one of them.
What you observe
- The panel works and accepts a temperature but the cavity stays cold — Control alive, heat absent — which splits the list into the heat path and the things that block it.
- Food takes far longer than it used to and never browns — Partial heat, which points at a sensor or a single element rather than at a dead circuit.
- The igniter glows but no flame ever appears — On a gas cavity this is the single most informative observation there is.
- The oven went cold straight after a self-clean cycle — That sequence points at thermal protection having tripped rather than at a part having failed.
- NEAR MISS — the whole panel is dark and nothing responds — No display and no response is a power or board fault and belongs on the will-not-start page, not here.
Causes, most likely first on the ACR family
- Bake element open, blistered or broken — First on this family. It fails at the end of a heating cycle when it is hottest, so the machine often works one day and does nothing at all the next.
- Oven temperature sensor reading wrong — Second on these models. A sensor reading high tells the board the oven has arrived when it has not, so the cavity never gets hot and nothing looks broken.
- Control board relay not closing the heat circuit — Third. It is the cause that explains a cold oven with a perfectly normal-looking control panel and no error at all.
- Broil element or the upper heat path — Last of the four, and the one to reach for only when the others are clean. Broil failures are reported as heating failures more often than they are recognised, since the oven still reaches temperature and simply never browns anything.
- Body: A brand-generic article on this symptom starts with the bake element, and so does this one.
Check in this order, and why
- Call bake from cold and watch the lower element for an even glow — No glow at all after several minutes, or a glow that stops part-way along, settles it without a meter.
- Put an oven thermometer on the middle shelf and compare it with the set point — A wide, repeatable gap between the thermometer and the panel points at the sensor rather than at the heat source.
- Listen at the console for the relay click when bake is called — A click with no heat points past the board; no click at all points at it, and either way the next step is a meter.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off, and a range circuit is a large-appliance circuit rather than a lighting one.

When to call a technician
Call once the free observations are done — glow or no glow, thermometer against set point, lock travel — because everything past them needs the back off and a meter on. Call for anything on the gas side without exception, including a valve that will not open with a healthy igniter.
