Frigidaire FGB24S5ABC gas wall oven Parts

Yes. 27-inch gas wall ovens exist, and the Frigidaire FGB24S5ABC is designed for a 27-inch cabinet cutout, so 27-inch gas wall ovens are a real, supported size (even though 30-inch models are more common).

What “27-inch” usually means

Most brands use “27-inch” as a nominal size. The actual cabinet opening and clearances are what matter for fit, venting, and safe operation.

From the installation requirements for this Frigidaire gas wall oven, the cutout width is shown as 27 inches for certain configurations. Use the installation guide to confirm the exact cutout and clearance requirements for your specific cavity style.

How to shop the right size (and avoid fit problems)

Before buying any 27-inch gas wall oven, we recommend matching these items:

• Cabinet cutout width, height, and depth (not just the advertised oven width)
• Door swing clearance so the door opens fully
• Gas hookup location and shutoff valve access
• Electrical outlet location and grounding method
• Venting and minimum clearances to combustibles

Quick fit checklist (typical items to compare)

Use this table to compare your cabinet opening to the oven’s installation requirements.

What to measure	Where to measure	Why it matters
Cutout width	Inside edges of the cabinet opening	Determines whether the oven frame fits
Cutout height	Bottom support surface to top of opening	Prevents binding and trim gaps
Cutout depth	Front of cabinet to back wall	Ensures the oven chassis clears
Door clearance	In front of the oven	Prevents the door from hitting nearby cabinets

Why it matters

A “27-inch” label does not guarantee a drop-in fit. Gas wall ovens also have strict requirements for grounding, shutoff valves, and safe clearances, so matching the installation specs is the fastest way to avoid returns and unsafe installations.

On a Frigidaire FGB24S5ABC gas wall oven, an F045 error typically points to a problem in the oven’s electronic control system, most often the keypad (touchpad) or its wiring connection to the control. We fix it by resetting power, checking keypad wiring, and replacing the failed control component when the code returns.

Quick reset and safety first

• Turn the oven control to OFF.
• Shut off power at the breaker for 1 minute, then restore power.
• If the code returns, stop using the oven until you complete the checks below.
• If you smell gas, do not operate the oven; shut off the gas supply and have service performed.
• Follow the power-failure guidance and shutoff steps in the FGB24S5ABC installation guide.

What to check (most common causes)

1. Keypad or touchpad ribbon connection

   • Remove power.
   • Access the control area and reseat the ribbon connector fully.
   • Look for discoloration, corrosion, or a loose latch.

2. Damaged wiring or connector pins

   • Inspect for pinched wires, heat damage, or broken conductors.
   • If you find damaged wiring, repair it correctly or replace the harness.

3. Failed oven temperature sensor (less common for this code, but worth ruling out)

   • If the oven also overheats, underheats, or behaves erratically, test the sensor circuit.
   • For this model, the sensor part is Frigidaire range oven temperature sensor 316217002.

Basic troubleshooting flow (what to do next)

• F045 clears after reset and stays cleared: monitor; no repair needed.
• F045 returns immediately: keypad/touchpad circuit is the top suspect.
• F045 appears during heating: inspect wiring near hot areas; check sensor circuit.

Symptom you see	Most likely area	Typical fix
Code returns as soon as power is restored	Keypad/touchpad connection	Reseat connector; replace keypad/control if needed
Random beeping or unresponsive buttons	Touchpad	Replace touchpad/control overlay assembly
Temperature swings plus error	Sensor or wiring	Test sensor; repair wiring; replace sensor if out of spec

Why it matters

An F045 control fault can cause unreliable operation, including unexpected heating behavior after a power interruption. The installation instructions emphasize turning the control OFF during a power failure to prevent the oven from operating when power returns.

To reset your Frigidaire FGB24S5ABC gas wall oven, turn the oven off and restore power by unplugging it (or switching the circuit breaker off, then back on). This clears many control glitches and is the first step before troubleshooting an error code.

Reset steps (safe, basic)

• Turn all oven controls to OFF.
• Switch the circuit breaker OFF (or unplug the oven if accessible).
• Wait 1 to 5 minutes.
• Restore power.
• Set the oven to 300°F and confirm normal ignition and cycling.

If the oven still will not heat after a reset

The installation instructions for this model emphasize checking the home fuse or circuit breaker first, then confirming the igniter system operates normally after power is restored.

• Verify the house fuse/circuit breaker is not blown or tripped.
• Make sure the oven door is closed, then set 300°F; the burner typically ignites in about 60 seconds.
• If you smell gas or suspect a gas leak, shut off the gas supply and stop using the oven.

Common symptoms and likely direction

What you notice	What it usually points to	What we check next
No heat, no ignition	Ignition problem	Inspect/test the igniter and wiring
Slow ignition, weak heat	Weak igniter	Replace the igniter
Oven heats but temps are off	Temperature sensing issue	Test the sensor

Parts that commonly relate to “won’t heat” or “won’t ignite”

If the reset does not help and the burner does not light reliably, these model-matched parts are common suspects:

• Frigidaire range oven burner igniter 5303935066 (ignites the gas at the burner)
• Frigidaire range oven temperature sensor 316217002 (reports oven temperature to the control)

Why it matters

A reset can clear a temporary control fault, but repeated ignition failures usually mean the oven is not lighting consistently. Fixing the root cause helps prevent undercooking, long preheat times, and repeated shutdowns.

For model-specific electrical grounding and safety notes (including disconnecting power before service), follow the FGB24S5ABC installation guide.
