Frigidaire FEF339FSC electric range Parts

On the Frigidaire FEF339FSC electric range, an F30 error points to a problem in the oven temperature sensing circuit (most often the oven temperature sensor or its wiring). We fix it by checking the sensor resistance, inspecting the harness connections, and replacing the failed part if readings or wiring are out of spec.

What to check first (fast, safe steps)

• Turn off power at the breaker before touching any wiring.
• Let the oven cool completely.
• Inspect the sensor connector and harness for loose pins, corrosion, or heat damage.
• Reseat the connector firmly; a partially backed-out plug can trigger F30.
• If the code returns, test the sensor circuit with a multimeter.

How to test the oven temperature sensor (basic method)

1. Disconnect power.
2. Access the sensor connector (typically inside the oven cavity or from the rear, depending on the build).
3. Unplug the sensor from the harness.
4. Measure resistance across the sensor terminals.

Most Frigidaire-style oven sensors read about 1,080 ohms at room temperature (around 70°F). A reading that is open (infinite), shorted (near 0), or far from typical indicates a bad sensor.

Test result	What it usually means	What we do next
~1,080 ohms at room temp	Sensor likely OK	Check wiring/connector to control
Open circuit (OL/infinite)	Sensor or wire is broken	Replace sensor or repair harness
Very low resistance	Sensor shorted	Replace sensor

Parts that commonly solve F30 on this model

If your sensor tests bad, the replacement is typically the oven temperature sensor. For this model page, the listed sensor is the oven probe 316233903.

If the sensor tests good, the issue is commonly a damaged harness/connector or a control problem. If you see burning at the power connection area, inspect the terminal block and wiring; the model page lists the kelvinator range terminal block 5304409888.

Why it matters

When the control cannot trust the temperature signal, it may shut down heating for safety and accuracy. Fixing the sensor circuit restores normal baking, prevents overheating, and stops nuisance shutdowns.

To reset your Frigidaire electric range model FEF339FSC, turn the range off and reset power at the breaker (or unplug it) for about 30 seconds, then restore power. This clears many control glitches; if the oven or burners still do not heat, focus next on power supply and heating components.

Safe reset steps (recommended)

• Set all surface controls to OFF.
• If the range is plugged in, unplug it; otherwise switch the range breaker OFF.
• Wait 30 seconds.
• Restore power.
• Set the clock and test Bake and one surface element.

If it still will not heat after a reset

A reset will not fix a loss of 240V power or a failed heating circuit. Check these common causes:

• Tripped breaker: many electric ranges use a 2-pole breaker; one side can trip and leave you with partial power.
• Loose power cord/terminal connection: a burned or loose connection can stop heating.
• Failed bake or broil element: the oven may not heat properly if an element is open.
• Temperature sensor issue: inaccurate sensing can cause poor heating or error codes.
• Control problem: a failed electronic control can prevent elements from energizing.

Parts that commonly relate to “no heat” symptoms

Symptom	Most likely area	Example part for FEF339FSC
Oven will not bake	Bake heating circuit	Range bake element 316075103
Oven will not broil	Broil heating circuit	Range broil element 316203200
Oven temperature is erratic	Temperature sensing	Oven probe 316233903
Burners act up or do not regulate	Surface control	Range surface element control switch 316436001

Why it matters

Resetting power is a fast way to clear a stuck control state, but electric ranges still need a solid 240V supply and working elements, sensor, and controls to heat correctly. Identifying whether the issue is power-related or part-related saves time and prevents repeat failures.

A Frigidaire electric range like model FEF339FSC typically lasts 13 to 15 years with normal household use. Keeping the oven temperature accurate and fixing heating issues early (like a weak element) helps you reach the full expected lifespan.

What affects lifespan most

• Heavy daily cooking and frequent self-clean cycles
• Power supply issues (loose cord connections, overheating at the terminal block)
• Worn heating components (bake and broil elements)
• Door seal leaks that force longer heat times
• Control problems that cause temperature swings

Quick checks that help your range last longer

• If baking is slow or uneven, inspect the bake element for blisters, cracks, or burn spots; replace it if damaged.
• If broil is weak, check the broil element for visible damage.
• If the oven runs hot or cold, test temperature with an oven thermometer and consider the sensor/probe.
• If you smell hot wiring or see discoloration at the power connection, stop using the range and inspect the terminal block.

Common wear items for FEF339FSC

Symptom	Likely wear item	Example part on this model
Oven not heating or uneven baking	Bake element	Frigidaire range bake element 316075103
Broil not working	Broil element	Frigidaire range broil element 316203200
Oven light out	Bulb or socket	Range oven light bulb 316538904
Oven temp inaccurate	Temperature sensor/probe	Oven probe 316233903

Why it matters

Most “range is worn out” complaints are actually a single failed part (element, probe, switch, or wiring connection). Replacing the right component restores safe, consistent heating and can extend the service life of your Frigidaire FEF339FSC.
