Frigidaire Oven Not Heating
Quick answer: The oven turns on and the display or knob responds, but the cavity stays cold or only gets lukewarm. On electric ranges the bake element is by far the most common cause, followed by the oven temperature sensor, a failed relay on the control board, and a burned wire terminal at the element.
- Unplug the range or switch off its circuit breaker before removing any panel or touching element terminals. Electric ranges run on 240 volts.
- On a gas range, close the gas shutoff valve behind the range before disconnecting any gas component, and never test for leaks with a flame.
- Let the oven cool completely before working inside the cavity; elements and igniters stay hot long after the oven is turned off.
Why is my oven not heating?
The oven turns on and the display or knob responds, but the cavity stays cold or only gets lukewarm. On electric ranges the bake element is by far the most common cause, followed by the oven temperature sensor, a failed relay on the control board, and a burned wire terminal at the element. On gas ranges a weak or failed oven igniter is the usual culprit, followed by the gas safety valve and the control.

Most Likely Causes, in Order
1. Bake element burned out (electric)
The bake element is a resistance heater that runs on 240 volts. Over years of heating and cooling the metal sheath and inner coil fatigue, and eventually the coil opens, blisters, or arcs to the sheath. Once open, no current flows and the oven produces no bottom heat.
How to check: Set the oven to bake at 350 and watch the lower element after a few minutes; a healthy element glows evenly red along its full length. Look for blisters, breaks, bubbles, or a spot that looks burned or split. With power off, disconnect the element wires and measure resistance across the two terminals; most bake elements read roughly 15 to 40 ohms, and an open reading means the element has failed.
Fix: Replace the bake element. Remove the two mounting screws inside the cavity, pull the element forward, transfer the wires one at a time so they do not fall back into the wall, and screw the new element in place. If a wire terminal is burned, replace the connector as well. (Difficulty: Easy)

2. Oven igniter weak or failed (gas)
A gas oven uses a hot-surface igniter wired in series with the safety valve. The igniter must draw enough current to open the valve; as the silicon carbide or nitride element ages it still glows but draws less current, so the valve never opens and the burner never lights.
How to check: Remove the oven bottom panel or look through the vent, set the oven to bake, and watch the igniter. It should glow bright orange and the burner should light within about 30 to 90 seconds. If it glows for more than 90 seconds without a flame, or glows dull orange, the igniter is weak. A clamp meter on the igniter lead typically shows 3.2 to 3.6 amps for a flat igniter and 2.5 to 3.0 amps for a round one when healthy.
Fix: Replace the igniter. Shut off gas and power, remove the oven bottom and burner baffle, unscrew the igniter bracket, unplug its connector, and install the new one without touching the fragile element with bare fingers. Restore power and confirm the burner lights within the normal time. (Difficulty: Moderate)

3. Oven temperature sensor faulty
The sensor is a thin probe inside the cavity whose resistance rises with temperature. If it drifts, shorts, or opens, the electronic control either thinks the oven is already hot and never turns on the heat, or it detects a fault and displays an error code.
How to check: With the oven cold and power off, unplug the sensor connector behind the rear panel or at the sensor itself and measure its resistance. Most sensors read about 1080 to 1100 ohms at room temperature. A reading far from that, an open circuit, or a short indicates a bad sensor. Also inspect the connector for corrosion or burned pins.
Fix: Replace the sensor. It is held by one or two screws at the back wall of the cavity; pull it forward, unplug the harness connector, and plug in and screw down the new one. (Difficulty: Moderate)

4. Control board relay failed
The electronic oven control switches power to the bake element or igniter through relays soldered on the board. A relay contact can burn open or the driver circuit can fail, so the control shows the set temperature but never sends voltage to the heater.
How to check: Rule out the element or igniter and the sensor first. Then, with the range plugged in and the oven set to bake, carefully measure the voltage at the bake output terminals of the board or at the element leads; electric ovens should see about 240 volts, gas ovens about 120 volts on the igniter circuit. No voltage with good wiring points to the board. Also look for scorched areas or a relay that clicks but does not pass power.
Fix: Replace the oven control board. Photograph every connector before unplugging, transfer the overlay or keypad if the new board ships bare, and mount the new board in the same position. (Difficulty: Advanced)

5. Burned wire terminal or broken harness wire
High current through a loose spade connector heats it until the metal oxidizes and the insulation chars. Eventually the connection fails and the element or igniter receives no power even though every part tests good.
How to check: With power off, pull the element forward and inspect both spade terminals and the wire ends for discoloration, melted insulation, or a connector that slides on loosely. Trace the wires back through the rear panel and check for a break or a chewed spot. A continuity test from the board connector to the element terminal confirms the run.
Fix: Cut back the damaged wire to clean copper and crimp on a new high-temperature terminal, or replace the affected section of harness. Make sure the new connector grips the element terminal firmly. (Difficulty: Moderate)

6. Gas oven safety valve failed
The safety valve opens only when the igniter draws full current through its bimetal. If the valve coil or bimetal fails, gas never reaches the burner even though the igniter glows brightly.
How to check: Confirm first that the igniter glows brightly and draws the correct amperage; a good igniter with no flame after 90 seconds points to the valve. With power off, measure resistance across the valve terminals; a typical bimetal valve reads only a few ohms, and an open reading means it has failed.
Fix: Replace the safety valve with the gas shut off, using new fittings or thread sealant rated for gas, then leak-test every joint with soapy water before relighting. (Difficulty: Advanced)

Frequently Asked Questions
The broiler works but bake does not. What does that mean?
Broil and bake use separate heaters, so a working broiler tells you the range has power and the control is at least partly working. On an electric oven that almost always means the bake element is open; on a gas oven it usually means the bake igniter is weak.
The igniter glows but the oven never lights. Is the igniter still bad?
Usually yes. A glowing igniter can still be too weak to draw the current needed to open the safety valve. If it glows for more than about 90 seconds without a flame, replace the igniter first; only suspect the valve if a new igniter does not fix it.
Can I keep using the range if only the oven does not heat?
On an electric range you can keep using the cooktop, since the surface elements are on separate circuits. On a gas range, do not run the oven repeatedly while it fails to light, because unburned gas can accumulate in the cavity.
When to Call a Professional
Call a technician if the element, igniter, and sensor all test good, if you find scorched wiring or a burned control board, or if any gas component such as the safety valve or gas line needs to be disconnected and you are not comfortable leak-testing the joints.
