Frigidaire FEFB66ECC electric range Parts

To reset your Frigidaire electric range model FEFB66ECC, turn the range off and restore power with a quick power cycle (unplug for about 30 seconds, then plug back in). If the oven or all burners still do not heat, focus next on the home power supply and range wiring.

Reset steps (safe, quick checks)

• Set all surface controls to OFF.
• If the range is plugged in: unplug it for 30 seconds, then plug it back in.
• If it is hardwired: switch the range breaker OFF, wait 30 seconds, then switch it ON.
• Confirm the display and controls respond normally after power is restored.
• If the range was just installed, recheck that the anti-tip bracket is engaged and the unit is level (installation issues can also point to wiring problems).

If the range still will not heat after a reset

A “reset” only clears minor control glitches. No-heat symptoms usually come from a power supply problem (missing one leg of 240V), a loose connection, or a failed heating circuit component.

Most common causes

• Tripped breaker or a breaker that is only partially tripped (common with 2-pole breakers)
• Loose or overheated connection at the terminal block
• Burned wiring at the power cord connection
• Failed oven heating part (bake or broil element)
• Failed control component (clock/timer or wiring harness)

What to check first (power and wiring)

The installation instructions for this range emphasize secure terminal block connections and warn not to loosen factory-installed nuts that secure internal range wiring.

Symptom	What it usually points to	What we recommend next
Clock works but oven and burners do not heat	Missing one “hot” leg of 240V	Check breaker and terminal block wiring per the FEFB66ECC installation guide
Oven does not bake but broil works	Bake circuit issue	Inspect and test the Frigidaire range bake element 316075103
Oven does not broil but bake works	Broil circuit issue	Inspect and test the Frigidaire range broil element 316203200

Why it matters

A proper reset is a good first step, but electric ranges need a correct 240-volt supply to heat. A wiring or terminal block problem can stop heating and can also damage connectors over time, so it is worth checking promptly.

On the Frigidaire FEFB66ECC electric range, a “666” display is typically treated like a fault condition tied to the oven temperature sensing circuit or the electronic oven control. The most common fixes are testing the oven temperature sensor resistance and, if it tests good, replacing the control.

What to check first (safe, quick steps)

• Cancel the cycle and try a basic Bake start to see if the code returns.
• Power reset: turn the range breaker off for 1 minute, then back on.
• If the code returns, stop using the oven until the cause is found (to prevent overheating or no-heat conditions).
• Confirm the range is installed safely and stable; the anti-tip bracket and electrical connection requirements in the FEFB66ECC installation guide are important any time you service or move the range.

How we diagnose “666” (sensor vs. control)

Most Frigidaire ranges use an oven temperature sensor (RTD). A common baseline check is the sensor resistance at room temperature.

• Expected sensor reading (typical): about 1080 ohms at room temperature
• If the sensor is open, shorted, or far off spec, replace the sensor.
• If the sensor reads correctly, the issue usually points to the electronic oven control/clock-timer or wiring/connectors.

Quick decision table

Test result	What it usually means	What to do next
Sensor resistance is far from ~1080 ohms	Bad temperature sensor	Replace sensor; inspect connector pins
Sensor resistance is normal	Control not interpreting sensor signal correctly, or wiring issue	Check harness connections; consider control replacement
Code appears after moving range	Pinched/loose wiring, terminal block issue	Inspect rear wiring and strain relief; correct routing

Parts that may be involved on FEFB66ECC

If testing points to the control side, the FEFB66ECC parts list includes a control assembly that commonly relates to display and oven operation:

• Clock timer 5304509493

(If you need a sensor or wiring part and it is not listed in the parts shown, match it by model number and description in the full FEFB66ECC parts breakdown.)

Why it matters

A bad sensor circuit or failing control can cause no heat, runaway heat, inaccurate temperatures, or repeated beeping/error displays. Addressing the root cause restores safe, predictable baking performance.

Yes. For a Frigidaire electric range like model FEFB66ECC, using the full model number is the most accurate way to find compatible replacement parts because it pulls up the correct diagrams and part list for your exact range configuration.

How to find and use the model number

The model number is on the appliance’s rating label; copy it exactly (letters and numbers) before searching.

• Check the oven frame area behind the storage drawer or lower panel
• Look around the door opening or on the side trim
• Write down the full model number: FEFB66ECC
• Use the model number to match parts by function (bake, broil, surface element, control)
• Confirm the part description matches what you are replacing

For installation-related details (clearances, leveling, anti-tip bracket checks, and electrical connection requirements), use the FEFB66ECC installation guide.

Examples of parts you can match to FEFB66ECC

Once you are on the correct model parts list, you can narrow down by the symptom or the part name.

What is not working	Common part category to check	Example part for this model
Oven will not bake	Bake heating circuit	Range bake element 316075103
Surface element will not heat	Infinite switch / control switch	Range surface element control switch 316436001
Oven light is out	Bulb or socket	Range oven light bulb 316538904

Why it matters

Frigidaire ranges often have multiple versions that look similar but use different wiring, switches, and heating elements. Searching by FEFB66ECC helps prevent ordering a part that fits a different series or revision.

A Frigidaire Gallery electric oven typically lasts 10 to 15 years with normal household use. For a Frigidaire range like model FEFB66ECC, routine cleaning, avoiding overheating, and replacing wear items (like heating elements) on time can keep it cooking reliably longer.

Typical lifespan and what usually fails first

Most electric ranges reach the 10 to 15 year range before age-related failures become more common. The first issues are usually heat-related parts and door sealing.

Common wear items on an electric range:

• Bake element and broil element (no heat, slow preheat, uneven baking)
• Surface element control switch (burner stuck on, burner will not heat)
• Oven door seal (heat leaks, longer cook times)
• Oven light bulb or socket (light out or flickering)
• Electronic clock/timer or control overlay (display issues, buttons not responding)

Repair vs replace: a practical rule of thumb

If the oven heats correctly and the cooktop works, replacing a few parts is often the most cost-effective way to extend life.

Situation	What it usually means	Typical next step
Oven will not bake but broil works	Bake circuit issue	Test and replace the range bake element 316075103 if failed
One surface burner will not regulate	Switch issue	Check the correct surface switch for that burner
Oven takes much longer to preheat	Heat loss or weak element	Inspect door seal and bake element
Display or timer acts erratic	Control issue	Consider control/timer diagnosis

Why it matters

Knowing the expected lifespan helps you plan: a 12-year-old range that only needs a bake element is usually worth repairing, while repeated control or wiring problems can signal it is nearing end-of-life.

Safety note for older ranges

If you move the range for service, follow the grounding and connection guidance in the FEFB66ECC installation guide. Proper electrical connections and anti-tip setup help prevent shock and tip hazards.
