The short answer
When an AFCS oven will not reach temperature, the question that sorts the list is whether it is heating at all or heating badly. The generic Amana answer cannot make that split for you; here it decides everything below.
What you actually observe
- Food is consistently underdone at the usual setting — That is calibration or the sensor, not a failure.
- A bright scorch or blister on the element or the floor below it — Look along the whole loop, including the bends.
- The breaker tripped when the oven was switched on — That changes the order completely and makes the electrical checks first.
- NEAR MISS — the surface burners work and the oven does not — It does not narrow anything on its own.
Causes on the AFCS listings, most likely first
- 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. A dead broil element produces slow preheat and pale baking rather than a cold cavity. This family is a single listing, so what is true of it is true of every unit carrying the badge.
- One leg of the supply lost — A range runs its heating on both legs of a split supply and its control on one, so losing a leg leaves the clock and the lights working and the heat gone. A partially tripped breaker or a loose connection at the terminal block does it.
- A calibration that has drifted — Drift of a few degrees is normal over years, and it shows up as longer bakes rather than as no heat. Measure it before you correct it.
- A failed relay on the control board — This is where owner diagnosis ends on these models. Confirming it means reading for voltage at the element with the oven calling for heat.
Check in this order, and why
- 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.
- Check both halves of the breaker and the terminal block — Do this first if anything electrical has happened; do it last if the oven is simply slow.
- 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.
Models in the AFCS family — A single listing: there is no revision spread on this family to account for. A masked suffix in a listing covers the colour and trim variants of that model.

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. Call if the breaker trips again after one reset, because a circuit that trips twice is telling you something and it is not asking for a third try.
