Frigidaire FGF378ACH gas range Parts

Yes. For your Frigidaire FGF378ACH gas range, looking up parts by the exact model number is the most reliable way to get compatible replacement parts because it ties the search to your range’s specific burner ratings, fuel type, and factory gas-pressure setup. See the FGF378ACH owner’s manual for model and serial plate details.

Where to find the model number on FGF378ACH

On this Frigidaire range, the serial plate is typically on the right-hand surface of the oven front frame near the storage or warmer drawer, or in the lower panel area.

• Pull out the storage/warmer drawer and look along the right front frame
• Check behind the lower panel (on some versions)
• Write down the model number, serial number, and any lot number/letter
• Use the full model number exactly as shown (letters and numbers matter)

How to use the model number to get the right part

When you search by model number, you can match parts by function and fit, then confirm by description.

• Start with the full model number: FGF378ACH
• Choose the system you’re repairing (surface burners, oven burner, controls, lighting)
• Compare the part name and ID before ordering
• If you’re converting fuel types, verify the correct kit for your setup

Common examples for this model

What’s not working	Part type to check	Example part for FGF378ACH
Oven won’t ignite or heats slowly	Oven burner igniter	Range oven burner igniter 5303935066
Oven light out	Oven light bulb or socket	Range oven light bulb 316538904
Oven temperature seems off	Temperature sensor/probe	Oven probe 316233903

Why it matters

Using the model number helps prevent ordering a part that looks similar but does not match your range’s gas configuration or mounting style, which can lead to ignition problems, poor baking performance, or repeat repairs.

To remove the cooktop (main top) on your Frigidaire FGF378ACH gas range, we start by shutting off the gas supply and power, then removing the grates and burner pieces so the top can be lifted or unfastened safely. Follow the steps and fastener locations in the FGF378ACH installation guide.

Safety first (before you touch the cooktop)

• Turn all surface burner knobs to OFF.
• Shut off the manual gas shut-off valve to the range.
• Unplug the range or switch OFF the circuit breaker.
• If you need to pull the range forward, pull only as far as needed to access the connections.
• After any reconnection, check joints with a liquid leak detector (never use a flame).

Basic cooktop removal steps (typical for this Frigidaire-style sealed burner top)

1. Remove all burner grates.
2. Lift off the burner caps.
3. Remove the burner heads (on many models they lift off; some are secured with screws).
4. Look for screws at the front lip or under burner heads; remove them if present.
5. Lift the front of the main top and raise it; if it is hinged, support it.
6. If the top is tethered by wiring (spark module/igniters), do not strain wires; disconnect only what you must.

Parts you may handle during this job

Part you remove	What it does	Common issue if mis-seated
Burner cap	Spreads flame evenly	Uneven flame, clicking
Burner head	Mixes gas and air	Poor ignition, yellow flame
Mounting screws	Secure cooktop	Rattles, gaps

If a burner head is damaged or heavily corroded, replacement is often the cleanest fix; match it to your model, such as the range surface burner head 316212400 when applicable.

Why it matters

Removing the top correctly prevents gas leaks, pinched igniter wires, and burner alignment problems that cause delayed ignition or constant sparking.

Yes. Frigidaire makes gas ranges, and your Frigidaire FGF378ACH is a gas range model with features and installation requirements covered in the FGF378ACH owner’s manual and FGF378ACH installation guide.

What that means for parts and service

Because FGF378ACH is a Frigidaire gas range, you can shop and troubleshoot by gas-range systems such as the surface burners, oven burner ignition, oven temperature sensing, and the gas supply components.

Common gas-range parts customers replace include:

• Oven burner igniter (for no-bake or slow ignition symptoms)
• Surface burner head and cap (for uneven flames or poor ignition)
• Oven temperature sensor/probe (for temperature accuracy issues)
• Oven light bulb and light socket (for no interior light)
• Gas pressure regulator (for fuel supply regulation and conversions)

Quick model-specific checks (FGF378ACH)

Use these basics to confirm you are working with a gas range and to avoid common setup issues:

• Confirm the range is connected to the correct fuel type; many ranges are preset for natural gas.
• Verify clearances and overall dimensions before installation.
• Keep the range level and stable; an uneven floor can affect fit and alignment.
• For ignition problems, make sure the control knob is turned fully to the LITE position.

Helpful parts for common symptoms

Symptom	Most likely area	Example part for FGF378ACH
Oven will not heat (bake)	Oven ignition	Range oven burner igniter 5303935066
Surface burner flame is uneven	Burner head/ports	Range surface burner head 316212400
Oven temperature seems off	Temperature sensing	Oven probe 316233903

Why it matters

Knowing Frigidaire makes gas ranges (and that FGF378ACH is one) helps you choose the right repair approach: gas ignition and fuel supply issues are diagnosed differently than electric-element heating problems, and the correct parts must match the exact model.
