Can I look up Frigidaire parts by model number?
Yes. Looking up parts by model number is the most accurate way to get compatible replacement parts for your Frigidaire gas range model FPGF3685LSA, because the model number ties directly to the correct diagrams, burner ratings, and the exact parts list in the FPGF3685LSA installation guide.
For FPGF3685LSA, the installation instructions place the serial plate on the oven front frame behind the drawer. Use the full model number exactly as shown on that plate when searching.
Tips that prevent wrong-part orders:
- Write down the model number and serial number from the serial plate.
- Include any lot number or letter shown on the serial plate when ordering.
- Match the appliance type: Frigidaire gas range (not a wall oven or cooktop).
- If you are converting fuel or checking flame issues, note the fuel type and pressure listed on the plate.
- Use the model number first, then narrow by symptom (no bake, weak flame, no ignition).
Searching by model number filters out look-alike parts that fit other Frigidaire ranges but not yours.
| What you search | What you get | Risk level |
|---|---|---|
| Model number (FPGF3685LSA) | Exact parts list for your range | Lowest |
| Part name only (example: “igniter”) | Many similar options | Medium |
| Measurements or photos only | Often close but not exact | Highest |
If you are troubleshooting oven heat or ignition, these are frequently searched items for FPGF3685LSA:
- Range bake igniter 5303935066 (for bake burner ignition problems)
- Range oven temperature sensor 5304504897 (for temperature accuracy issues)
- Appliance light bulb, 40-watt 316538904 (for a burned-out oven light)
Using the correct model number helps ensure the part matches your range’s configuration, including burner ratings and fuel setup, so the repair is safer, faster, and avoids returns.

How do I tell what model my Frigidaire stove is?
For your Frigidaire gas range model FPGF3685LSA, the model and serial plate is located on the oven front frame behind the drawer. Pull the storage (or service) drawer out and look for the serial plate; use the exact letters and numbers when ordering parts.
On this Frigidaire range, the most reliable spot is behind the drawer on the oven front frame. When you find the plate, copy the model number and serial number exactly.
- Pull the storage/service drawer fully open and remove it if needed
- Look on the oven front frame behind the drawer opening
- Use a flashlight; the plate can be low and hard to see
- Write down the model number, serial number, and any lot number/letter
- Match characters carefully (for example, 0 vs O, 1 vs I)
For the exact drawer removal steps and the model/serial plate location callout, use the FPGF3685LSA installation guide.
Having the full ID information prevents ordering the wrong Frigidaire parts (igniters, burner heads, sensors) and speeds up troubleshooting.
| What you’ll see | What it’s used for |
|---|---|
| Model number (example: FPGF3685LSA) | Ensures parts fit your exact range configuration |
| Serial number | Helps match production changes within the same model |
| Lot number/letter (if shown) | Further narrows down correct replacement parts |
Frigidaire ranges can have multiple versions that look identical from the outside. Using the model and serial plate information helps us match the correct gas components and electrical parts for safe, reliable operation.

How to replace the igniter on a Frigidaire gas stove?
On the Frigidaire FPGF3685LSA gas range, first identify whether you are replacing the bake igniter (bottom burner) or the broil igniter (top burner). The access steps are similar: shut off power and gas, remove the correct oven panel, swap the igniter, then test ignition timing using the FPGF3685LSA installation guide.
Before you touch any wiring or gas components:
- Turn off the circuit breaker (or unplug the range)
- Close the manual gas shut-off valve
- Let the oven cool completely
- Pull the range forward only if needed; avoid pinching the flexible gas conduit
- Use a work light and gloves; sheet metal edges are sharp
Use this quick check so you install the right part in the right location:
| What is not working? | Igniter location | Part to check/replace |
|---|---|---|
| Bake will not heat | Bottom of oven at the bake burner tube | Range bake igniter 5303935066 |
| Broil will not heat | Top of oven near the broil burner | Range broil igniter 318177730 |
The mounting style varies slightly, but the workflow stays the same:
- Remove oven racks.
- Remove the panel that covers the burner you are servicing:
- Bake: remove the oven bottom panel (and flame spreader if equipped).
- Broil: remove the broil burner shield or upper cover (if equipped).
- Locate the igniter mounted to the burner tube.
- Remove the igniter mounting screws.
- Disconnect the igniter wiring connector (or wire nuts, depending on harness style).
- Install the new igniter in the same position; route wires away from hot surfaces.
- Reinstall all panels and racks.
A glow-bar igniter must heat up before the oven gas valve opens. Typical operation:
- Set oven to BAKE 300°F
- The igniter glows, then the burner lights after about 30 to 60 seconds
- Let it cycle once, then turn the oven off
Bake and broil igniters are different parts with different locations. Installing the correct igniter restores reliable ignition, normal preheat, and proper burner cycling.
