Frigidaire Oven Not Heating Up – Causes & Fixes

1. Burned-Out Bake Element (Electric Models)

The bake element is the coiled heating component at the bottom of the oven cavity. When it burns out or cracks, the oven won’t reach the set temperature or won’t heat at all.

1. Unplug the oven or switch off the circuit breaker before doing anything.
2. Open the oven door and visually inspect the bake element for visible breaks, blisters, or burn marks.
3. If damage is visible, the element needs replacing—skip to step 5.
4. If no damage is visible, set a multimeter to Rx1 and test the element for continuity by touching each probe to one terminal. A reading other than near zero ohms indicates a failed element.
5. Remove the two screws securing the element bracket, gently pull the element forward, disconnect the wires, and install the replacement.

2. Weak or Failed Oven Igniter (Gas Models)

On gas Frigidaire ovens, the igniter must draw enough current to open the gas valve. A weak igniter glows but never gets hot enough to open the valve, so the burner never lights.

1. Disconnect power and shut off the gas supply to the range.
2. Remove the oven bottom panel (usually two screws at the rear) to expose the burner and igniter assembly.
3. Watch the igniter when you turn the oven on: if it glows orange for more than 90 seconds without the burner igniting, it is too weak.
4. Test with a multimeter: a healthy igniter typically reads 0–1,100 ohms. A reading of “OL” (open line) means it has failed completely.
5. Disconnect the igniter wire harness, unscrew the igniter from the burner bracket, and install the replacement.
6. Restore power and gas, then test with a bake cycle.

3. Faulty Oven Temperature Sensor

The temperature sensor (also called an oven probe) tells the control board how hot the oven is. If it fails, the board may shut off heating elements prematurely or never activate them.

1. Unplug the oven from the wall outlet.
2. Locate the sensor—it is a thin metal probe mounted to the upper-rear interior wall of the oven cavity.
3. At room temperature (approximately 70 °F / 21 °C), the sensor should read close to 1,080–1,100 ohms on a multimeter. A reading far outside this range indicates failure.
4. Remove the one or two screws securing the sensor bracket to the oven wall.
5. Pull the sensor through the hole, disconnect the wire connector, and connect the new sensor.
6. Reinstall the bracket, restore power, and run a test bake cycle to verify accurate heating.

4. Defective Electronic Control Board

The electronic control board governs every heating function in the oven. Burned relay contacts or failed components on the board can prevent the bake or broil circuits from ever activating.

1. Unplug the oven and allow it to cool completely.
2. Remove the back panel of the control console (usually several screws along the top or rear).
3. Inspect the control board visually for burn marks, scorch spots, or swollen capacitors—any of these are a clear sign of board failure.
4. If the bake element and temperature sensor have already tested good, a faulty board is the likely culprit.
5. Note the wiring positions with a photo before disconnecting any connectors, then swap in the replacement board.
6. Restore power and test all heating functions before reassembling the console.

5. Blown Thermal Fuse

Frigidaire ovens include a thermal fuse that blows if the oven overheats, cutting power to the heating circuit as a safety measure. Once blown, the fuse must be replaced—it cannot be reset.

1. Unplug the oven and pull it away from the wall to access the rear panel.
2. Remove the rear access panel screws and set the panel aside.
3. Locate the thermal fuse—it is typically a small cylindrical or rectangular component mounted near the oven cavity wall or on the control board bracket.
4. Test it with a multimeter set to continuity mode. A blown fuse will show no continuity (open circuit).
5. Disconnect the two wires, remove the fuse, and install an identical-rated replacement.
6. Before reassembling, investigate why the fuse blew (blocked vents, failed cooling fan) to prevent a repeat failure.

6. Tripped Circuit Breaker or Faulty Terminal Block (Electric Models)

An electric Frigidaire oven requires a dedicated 240-volt circuit; if one leg of that circuit trips or the terminal block where the power cord connects is loose or burned, the oven will receive insufficient power and fail to heat.

1. Go to your home’s electrical panel and look for a tripped double-pole breaker labeled “Range” or “Oven.” Reset it by switching it fully OFF, then back ON.
2. If the breaker trips again immediately, stop and call an electrician—there is likely a wiring fault.
3. If the breaker holds, test the oven. If it still won’t heat, unplug the range and inspect the terminal block at the rear.
4. Look for darkened, melted, or loose wire connections on the terminal block. Any sign of arcing means the terminal block should be replaced.
5. Tighten any loose screws on the block; replace the block entirely if burned.
