Frigidaire Oven Not Heating — Bake Element, Temperature Sensor & Relay Board Fix

Common Symptoms

• Oven does not heat at all when bake is selected
• Oven heats slowly or never reaches the set temperature
• Bake element glows orange at one spot only, then trips the breaker
• Oven works on broil but not bake (or vice versa)
• F10 or F30/F31 error code appearing alongside no-heat symptom
• Self-clean cycle runs but oven won't heat for normal baking
• Gas oven igniter glows but gas does not ignite

Most Likely Causes

1. 1

   Burned or Cracked Bake Element (Most Common — Electric)

   The bake element is a coiled resistance heater mounted at the bottom of the oven cavity on electric Frigidaire ranges. It heats the oven for bake cycles and provides the majority of heat during self-clean. When the element fails, it typically shows a visible burn spot, a crack, or a hole where the coil has blown. A failed element breaks the circuit — the oven will turn on and the control board will activate, but no heat is produced. Part 318255006 is a common Frigidaire bake element (~$30). Test with a multimeter: a good element reads 20–40 ohms; an open (failed) element reads OL.

2. 2

   Failed Oven Temperature Sensor (RTD Probe)

   The oven temperature sensor (RTD — Resistance Temperature Detector) is a thin metal probe mounted inside the oven cavity near the top rear. It measures oven temperature and sends that reading to the control board, which adjusts the bake or broil element cycling. A failed sensor causes the control board to misread the temperature — the oven may not heat (board thinks it's already at set temperature), heat continuously without shutoff (F10 runaway), or display F30/F31 error codes. The sensor should read approximately 1,080–1,100 ohms at room temperature (70°F). Part 316490000 (~$20) is the replacement RTD sensor for many Frigidaire electric ranges.

3. 3

   Burned or Failed Broil Element (Broil Failure Only)

   The broil element is mounted at the top of the oven cavity. On most Frigidaire electric ranges, the broil element also assists during the preheat phase of bake cycles. A failed broil element may cause the oven to heat slowly or fail entirely on broil. Inspect the element for visible burn spots or cracks. Test with a multimeter for continuity — a working broil element reads 10–30 ohms; OL indicates failure.

4. 4

   Relay Board or Control Board Failure

   The relay board controls power to the bake and broil elements based on signals from the main control board. Burned relay contacts on the relay board can prevent the element from receiving power even though the control board is sending the correct signal. Visible burn marks, melted plastic, or a carbon smell on the relay board indicate failure. A failed main control board is less common but possible — typically diagnosed after all elements and the sensor test good.

5. 5

   Thermal Limiter (Thermal Fuse) Blown

   Frigidaire ovens include one or more thermal limiters (thermal fuses) that cut power to the heating circuit if the oven overheats — typically during self-clean cycles. A blown thermal limiter interrupts the circuit permanently and prevents the oven from heating until replaced. Test with a multimeter for continuity — a blown limiter reads OL. Thermal limiters are non-resettable and must be replaced after a self-clean overheat event.

6. 6

   Gas Oven Igniter Failure (Gas Models Only)

   On gas Frigidaire ranges, the bake igniter is a silicon carbide or silicon nitride element that glows to ignite the gas burner and simultaneously acts as a safety valve — it draws enough current when hot to hold the gas valve open. A weak or partially failed igniter may glow red but not draw enough current (3.2–3.6 amps) to open the gas valve, so the burner never lights. Listen and watch: if the igniter glows for more than 90 seconds without the burner igniting, the igniter is weak and should be replaced.

Quick DIY Checks

1. 1Perform a visual inspection of the bake element first — takes 2 minutes and often reveals the failure immediately. Open the oven door and look at the bake element at the bottom of the cavity. Look for a visible hole, burn mark, crack, or dark spot anywhere along the coil. If you see a break or burn area, the element has failed and needs replacement. A good element is uniform in color and shape with no breaks. If it looks intact, proceed to the resistance test.
2. 2Test bake element resistance with a multimeter. Turn the circuit breaker OFF for the range. Remove the two Phillips screws securing the bake element mounting bracket to the oven back wall. Pull the element forward slightly and disconnect the two wire connectors (press the tab and pull). Set a multimeter to ohms (Ω). Touch the probes to the two element terminals. A working bake element reads 20–40 ohms. An OL (open/infinite) reading confirms the element has failed. Frigidaire part 318255006 (~$30) fits many Frigidaire and Electrolux-platform ranges — verify with your full model number.
3. 3Test the oven temperature sensor (RTD probe). With the circuit breaker OFF, locate the RTD sensor — a thin metal rod mounted inside the oven at the upper rear, attached with 2 screws. Unplug the sensor connector at the back of the oven wall. Set a multimeter to ohms. Probe the two sensor terminals. At room temperature (68–75°F), the reading should be 1,080–1,100 ohms. A reading below 500 ohms or OL (open circuit) indicates a failed sensor. Part 316490000 (~$20) is the replacement RTD probe for many Frigidaire electric ranges.
