The short answer
On Frigidaire Gallery an oven that will not come up to temperature is most often only part of the electrical supply reaching the oven. Ranked that way because the relays and the sensor both sit on the control side, so what looks mechanical from the front is often electronic underneath.
What you observe
- The display lights but nothing gets warm at all — Points at a mode, a missing supply leg or a failed element rather than at calibration.
- It broils but will not bake, or the reverse — That names which element has failed without any tool at all.
- NEAR MISS: it heats fine but the food burns or undercooks on one side — That is a distribution or door problem, not a heating failure. Read the door-seal page for this brand.
Causes, most likely first on Frigidaire Gallery
- Part of the electrical supply is missing — First here, where the control sits between you and the mechanical parts underneath. An electric oven that lights its display and heats nothing at all has often lost half of a double breaker: the control runs on one leg and the elements need both. It is a classic and it is checked before any part is bought.
- The bake or broil element has failed — Second, and the display will not name it for you. An element that has burnt through usually shows it: a bright spot, a blister, a break or a section that stays dark while the rest glows. An oven that broils but will not bake, or the reverse, is naming the failed element for you.
- The oven is in a mode that does not heat as expected — Third. A timer left set to auto, a sabbath or demonstration mode, a delayed start, or a fan-only setting will each give an oven that lights up and stays cold.
- A relay, the control board or a thermal cut-out has failed — Last, and it is the reason the order above matters. Mode, elements, sensor and supply all check out and the oven still will not heat.
Check in this order, and why
- Switch the double breaker fully off and back on, and retest — It explains a fully lit control with no heat whatever, which nothing else quite does.
- With the oven cold, look along the element for a break, a blister or a bright scar — A visible break is a confirmed cause, and the bake-versus-broil test narrows it without any tool.
- Read the display for a clock, an auto symbol or a lock before anything else — It costs nothing and it explains an oven with no fault at all.
What an owner can safely check
- Switch the double breaker fully off, then on, and retest on a plain bake setting — A breaker that trips again is a fault: leave it off and call rather than resetting it repeatedly.
About 15 min
- Inspect the visible element cold, then test bake and broil separately — Stop there.
Tools: torchAbout 15 min
- Cancel any timer or delayed start, select a plain bake setting and a temperature — An oven that heats after this was never faulty.
About 10 min
- STOP HERE if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Switch the oven off at its breaker before removing any panel or touching an element, and let the cavity cool fully first. An oven element carries far more than a lighting circuit and its terminals are live at the back. If you smell gas at a gas oven, do not switch anything on or off, leave the building, and call the gas utility or the emergency services from outside.
When to call a technician
Call when the mode is right, the elements look sound, the supply is complete and the oven still will not heat, because that puts the fault in a relay, a cut-out or the control. Call immediately if you smell gas, if the breaker trips when power is restored, or if you can see arcing or scorching at an element terminal.

What this page does not cover
This page covers the brand and the oven class, not one family or model line. Where a family-specific or model-specific page exists for your unit, that page is the more specific answer and it takes precedence over this one. Not here: part numbers, wiring colours and component locations, which differ by family.
