The short answer
A YAER oven that lights the display but never gets hot has usually lost the last link in the chain rather than the first. Where the brand-generic page starts at the control board, this one starts at the element, because on these models that is the part that fails. A cavity that warms slowly and one that stays stone cold are two different faults.
What you actually observe
- The broiler works but bake does not — One function lost and the other kept is the most useful thing this oven can tell you.
- Food is consistently underdone at the usual setting — An oven thermometer confirms it in one bake.
- A bright scorch or blister on the element or the floor below it — An element fails visibly more often than not.
- NEAR MISS — the surface burners work and the oven does not — It does not narrow anything on its own.
Causes on the YAER listings, most likely first
- A failed bake element — An element that has burned through usually shows it: a blister, a break, or a bright scorch on the cavity floor beneath it. A broken bake element gives you a cavity that stays cold while everything on the panel behaves normally. The listings above differ by trim rather than by mechanism, so which trim you own does not move this ranking.
- An oven temperature sensor out of tolerance — This ranks high on the shorter runs in this family because those listings share a single sensor part across every revision. An oven thermometer on the middle rack settles it in one bake.
- A failed broil element masking the fault — On these models the broil element also contributes to preheat, so losing it gives you an oven that heats but takes far too long and never quite arrives. Bake alone will look almost right, which is why this fault is usually reported as a temperature problem rather than a failure.
- A failed relay on the control board — The board switches the element through a relay, and a welded or burnt relay gives you a control that is fine and an element that never sees power.
Check in this order, and why
- Cancel every timer and mode, then run a plain bake — It is free, it takes a minute, and a control left in a timed or locked state is a common reason for a cold oven.
- Run the broiler briefly and watch it — This splits an element fault from a control fault without any tools, because they share a board and not a part.
- Put an oven thermometer on the middle rack — Only worth doing on an oven that heats at all, and conclusive when it is a calibration question.
- Watch the igniter through a full light attempt on a gas listing — How long it glows before gas arrives, or whether gas arrives at all, is the whole diagnosis.
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. A standard US household branch circuit is 15 A or 20 A at 120 V; a large appliance circuit is typically 30 A or higher at 240 V. An oven circuit is not one to work on live under any circumstances. If you smell gas, do not switch anything on or off, leave the building, and call the gas utility from outside.

When to call a technician
The line on these listings is the rear cavity panel. In front of it you are checking settings, the door and the breaker; behind it are live terminals and, on the gas listings, a supply you should not open.
