Frigidaire FGB504CHBA gas wall oven Parts

To reset a Frigidaire wall oven model FGB504CHBA, we recommend doing a power reset: turn the oven controls to OFF, shut off power at the breaker (or unplug if accessible) for about 1 minute, then restore power and set the clock. Use the FGB504CHBA owner's manual for the exact control steps.

Quick reset steps (power reset)

• Turn all oven controls and any programmable timer functions to OFF.
• Shut off power at the circuit breaker (preferred for a wall oven).
• Wait 60 seconds.
• Restore power.
• Reset the clock, then test Bake at 300°F to confirm normal operation.

If the oven still will not heat after a reset

A reset restores the control logic, but it will not fix an ignition or gas supply problem. The installation instructions for this type of Frigidaire gas wall oven call out checking that the house fuse or circuit breaker is OK and verifying igniter operation after gas connections are confirmed leak-free.

Common checks we use:

• Confirm the breaker is fully reset (OFF then ON).
• Make sure the manual gas shutoff valve is open.
• Listen for the igniter and watch for burner ignition within about a minute when set to 300°F.
• If the igniter glows but the burner does not light, the igniter can be weak and may need replacement.

If you suspect an igniter issue, the model parts list includes the uni ignitor 5303935066.

What a reset does (and does not do)

Action	What it helps	What it will not fix
Power reset (breaker off 1 minute)	Frozen display, minor control glitches, some error conditions	Failed igniter, gas valve issues, wiring damage, gas supply problems
Turning controls to OFF	Clears a timed function left running	Heating problems caused by failed parts

Why it matters

Resetting the oven is the fastest way to clear a temporary control issue and confirm whether you have a control problem or a heat/ignition problem. Testing Bake at 300°F after the reset is a practical way to verify the burner cycles normally.

Yes. Gas wall ovens are a real product category, and your Frigidaire FGB504CHBA is an example of a gas wall oven that uses gas for heat but still requires a properly grounded electrical connection for controls and ignition. For model-specific safety and hookup details, use the FGB504CHBA installation guide.

What “gas wall oven” means (and what it still needs)

A gas wall oven burns natural gas or LP gas for baking and broiling, but it also relies on electricity for items like the igniter, controls, and timer.

• Gas provides the heat at the burner.
• Electricity powers ignition and oven controls.
• The oven must be properly grounded.
• You should not operate the oven during a power failure.
• Gas connections must be leak-tested using a liquid leak detector or manometer (never a flame).

Quick comparison: gas vs. electric wall ovens

Feature	Gas wall oven (like FGB504CHBA)	Electric wall oven
Heat source	Gas burner	Electric bake/broil elements
Electrical requirement	Yes (controls and ignition)	Yes (all heating and controls)
Power failure behavior	Do not operate; turn controls OFF if power fails	No heat without power

Parts that commonly support gas-oven operation

If your gas wall oven won’t heat or struggles to ignite, these are common areas we check first.

• Ignition system (hot surface igniter)
• Gas supply and manual shutoff valve position
• Pressure regulator setting (natural gas vs. LP conversion)
• Wiring connections and grounding
• Oven light and control panel components

For ignition-related symptoms on this model, the uni ignitor 5303935066 is a common replacement part.

Why it matters

Knowing whether you have a gas wall oven helps you troubleshoot correctly. A “no heat” complaint on a gas oven often points to ignition or gas supply issues, while an electric oven more often points to heating elements or power supply problems.

To calibrate the oven temperature on your Frigidaire FGB504CHBA gas wall oven, use the oven’s temperature offset (calibration) feature in the control settings so you can raise or lower the displayed baking temperature to better match actual oven temperature.

Before you calibrate

We recommend confirming the oven is actually off by a consistent amount before changing calibration.

• Use an oven thermometer or a probe rated for oven use.
• Preheat at least 20 to 30 minutes after the preheat signal.
• Test at 350°F and record the average of 2 to 3 cycles.
• Keep the rack in the center position.
• Avoid opening the door during the test (heat loss skews results).

Calibration steps (typical Frigidaire electronic control)

The exact button sequence can vary by control style, so follow the steps in the FGB504CHBA owner’s manual. In most Frigidaire wall ovens, calibration is done by entering a settings or bake adjustment mode, then changing the temperature offset in small increments.

What you are changing

Calibration does not make the oven heat faster; it changes the temperature the control targets during Bake.

Item	What it affects	What it does not affect
Temperature offset (calibration)	Bake temperature accuracy	Gas supply, igniter operation, preheat time
Preheat habits	Temperature stability	Control calibration value

If temperature is still off after calibration

If the oven is more than about 25°F off, swings wildly, or takes too long to ignite and stabilize, treat it as a heating system issue instead of a calibration issue.

• Verify the oven ignites reliably; many models should ignite within about 60 seconds when set to 300°F.
• Check for weak ignition, delayed ignition, or burner cycling problems.
• Confirm the unit has proper electrical power and the house breaker is not tripped.
• If the oven light is out, replace the bulb 316538904 so you can observe ignition and burner behavior more easily.
• If ignition is inconsistent, a common repair is replacing the igniter such as the uni ignitor 5303935066.

Why it matters

Correct calibration helps baking results match recipe times and temperatures, while persistent temperature errors can point to an igniter, burner, or control problem that calibration will not fix.
