Frigidaire FGB500CGBB gas wall oven - p5995323150 Parts

If your Frigidaire FGB500CGBB gas wall oven smells like gas, treat it as a potential gas leak first. Turn the oven off, avoid using electrical switches, and follow the “what to do if you smell gas” steps in the owner's manual before doing any troubleshooting.

What to do right away (safety first)

• Turn the oven control to OFF.
• Do not try to light the oven or any other appliance.
• Do not touch electrical switches or use a phone inside the building.
• Leave the area and follow your gas supplier’s instructions (or contact emergency services if needed).
• Do not resume use until the odor is gone and the cause is corrected.

Common causes when the oven is running

A brief, faint odor at ignition can happen, but a persistent gas smell usually points to a problem with ignition, combustion, or a connection.

• Weak or delayed ignition (gas flows before it lights)
• Dirty or restricted burner ports (poor flame pattern)
• Loose gas connection or failing seal at a joint
• Gas valve not closing fully

Parts that commonly relate to ignition and flame quality

If the oven is slow to light or you smell gas during preheat, these model-compatible parts are often involved:

Symptom	What it often points to	Example part for FGB500CGBB
Delayed ignition, gas odor before flame	Igniter not heating properly	Uni ignitor 5303935066
Weak/uneven bake flame	Burner ports restricted or burner issue	Range bake burner 5303210787
Odor seems tied to burner operation	Gas control issue	White-westinghouse wall oven gas valve 3203702

How we recommend checking for leaks (no flame)

For the FGB500CGBB, the installation guidance is clear: check gas connections with a manometer or a liquid leak detector, and never use a flame.

• With gas supplied, apply liquid leak detector to joints and connections
• Tighten connections if bubbles form
• Use pipe joint sealant rated for LP gas on pipe connections when applicable

Why it matters

A gas odor can signal incomplete combustion or a leak. Addressing it quickly protects your home and helps prevent damage to components like the igniter, burner, and gas valve.

Wall ovens like the Frigidaire FGB500CGBB are usually more complicated to repair than a freestanding range because key components are harder to access once the oven is installed in the cabinet. Many fixes are still doable, but they often require careful disassembly, gas shutoff, and electrical safety steps from the owner's manual.

What makes wall oven repairs more challenging

• Access: the oven is built-in, so you may need to partially pull it from the cabinet.
• Safety: you may need to shut off gas and disconnect power before servicing.
• Heat-related parts: igniters, burners, and wiring can be fragile and tightly packed.
• Reinstall steps: the oven must be leveled and connections checked after reassembly.
• Weight: built-in units are heavy; moving them safely often takes two people.

Repairs that are commonly manageable

These are typical DIY-friendly repairs when you follow the correct shutoff steps and use the right tools:

• Replacing a failed igniter (common when the burner will not light reliably): uni ignitor 5303935066
• Replacing the oven light bulb: bulb 316538904
• Replacing a damaged light socket: receptacle 316116400

Quick difficulty comparison

Repair type	Typical difficulty	Why
Oven light bulb	Easy	Minimal disassembly; basic hand tools
Igniter replacement	Medium	Requires access to burner area; careful handling
Gas valve or burner work	Hard	Gas connections and precise reassembly

What we recommend before you start

• Turn off electrical power at the breaker; confirm the oven is off.
• Shut off the gas supply before pulling the oven for service.
• Pull the oven out only as far as needed to disconnect power and access components.
• After reassembly, check operation (for example, ignition and burner cycling at 300°F).
• If the house fuse or circuit breaker trips, correct that issue before replacing parts.

Why it matters

Wall oven repairs often fail because of access and reinstallation issues, not because the part swap is difficult. Following the correct removal, shutoff, and operational check steps helps prevent gas leaks, wiring damage, and repeat failures.

Yes. Gas wall ovens are real, and your Frigidaire FGB500CGBB is a gas wall oven that uses natural gas or LP/propane (after proper conversion) for heat while still requiring electricity for safe operation and controls. Review the safety and installation requirements in the installation guide.

What makes a wall oven “gas”

A gas wall oven heats with a gas burner (typically at the bottom of the oven cavity) and uses an igniter and gas valve to light and regulate the flame.

Common gas wall oven components include:

• Gas shutoff valve and supply piping connection
• Pressure regulator and safety valve assembly
• Oven burner and flame spreader
• Hot-surface igniter (glow igniter)
• Electronic controls and wiring (still powered by electricity)

Important safety and power details (model-relevant)

The installation instructions for this style of oven call out two key points:

• Do not operate the oven during a power failure; turn the oven control to OFF if power goes out.
• Never use a flame to check for gas leaks; use a manometer or a liquid leak detector.

Gas vs. electric wall oven: quick comparison

Feature	Gas wall oven	Electric wall oven
Heat source	Natural gas or LP/propane burner	Electric bake/broil elements
Electrical power needed	Yes (controls, ignition, safety)	Yes (heating and controls)
Typical symptom when ignition fails	No heat, no flame	No heat, element not glowing

Why it matters

Knowing you have a gas wall oven helps you troubleshoot correctly. For example, “no bake heat” often points to ignition or gas delivery issues (not an electric heating element), and safe service requires shutting off both gas and electric supplies.

Parts that commonly relate to “no heat” on gas ovens

If your FGB500CGBB won’t heat, these model-listed parts are often involved:

• Uni ignitor 5303935066 (ignites the gas at the burner)
• Range bake burner 5303210787 (delivers gas flame for baking)
• White-westinghouse wall oven gas valve 3203702 (controls gas flow to the burner)

To reset your Frigidaire FGB500CGBB gas wall oven, turn all oven controls to OFF, then restore power by cycling the breaker (or unplugging if it’s on a cord). After power returns, confirm the oven is still set to OFF and re-set the clock or timer as needed (see the owner's manual).

Quick reset steps (safe, standard)

• Turn the oven temperature knob and any function controls to OFF.
• If a timer was used, reset all controls to OFF afterward.
• Turn OFF the circuit breaker to the oven for about 1 minute.
• Turn the breaker back ON.
• Reprogram the clock or any cooking settings.
• Test bake at a moderate temperature (example: 300°F) to confirm normal ignition.

What a reset fixes (and what it doesn’t)

A reset clears many temporary control glitches, especially after a power interruption. It does not fix a failed igniter, gas supply issue, or a control that is shorted.

Symptom after reset	Most likely cause	What to check next
Display or functions act “stuck”	Control glitch	Repeat reset; confirm controls are OFF
Oven won’t heat at all	Gas supply or ignition problem	Verify shut-off valve is open; watch for ignition
Burner tries but won’t light	Weak ignition	Inspect igniter glow; consider replacing uni ignitor 5303935066
Light doesn’t work	Bulb or socket issue	Replace bulb 316538904 or inspect receptacle 316116400

Why it matters

On the FGB500CGBB, leaving controls in an ON state during a power failure can cause the oven to begin operating again when power returns. Resetting to OFF and power-cycling helps you start from a known-safe state and makes troubleshooting more accurate.

If the oven still won’t operate after resetting

• Confirm the gas shut-off valve is open.
• Check the house fuse or breaker and make sure it’s fully engaged.
• If the oven was recently installed, re-check the gas connection steps in the installation guide.
• If the igniter does not light the burner within about a minute during a bake test, replace the igniter.
