How do I tell what model my Frigidaire stove is?
Your Frigidaire gas range model number is printed on the appliance identification plate. On PLGFZ390ECB, the ID plate is typically on the right-hand surface of the oven front frame at the storage or warmer drawer area, or in the lower panel area; copy the full model and serial exactly.
Check these common ID plate locations first:
- Open the storage drawer or warming drawer and look along the oven front frame (often the right-hand side)
- Look in the lower panel area near the drawer opening
- Use a flashlight and look for a silver or white rating plate with a barcode
- Write down the model number, serial number, and any lot number/letter shown
- Take a clear photo so you can zoom in later
The model number is a mix of letters and numbers (for example, PLGFZ390ECB). For parts lookup and service, we recommend recording everything shown on the plate.
| Item on ID plate | Example | Why we need it |
|---|---|---|
| Model number | PLGFZ390ECB | Matches the correct parts diagrams and parts list |
| Serial number | Varies | Helps identify production run details |
| Lot number/letter | Varies | Sometimes used to confirm exact configuration |
Frigidaire ranges can look similar across model families, but burner components, igniters, oven parts, and even hardware can vary by revision. Using the exact model number helps ensure you get the right replacement part the first time.
Once you have the model number, confirm operating details and identification plate guidance in the PLGFZ390ECB owner’s manual.

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 PLGFZ390ECB, because the model number ties directly to the correct diagrams, part lists, and revisions shown in the PLGFZ390ECB owner's manual.
For this Frigidaire range, the identification plate is typically found at the storage drawer or warming drawer area. The manual also notes the serial plate location by opening the warming drawer (some models) or storage drawer (some models).
- Open the warming drawer or storage drawer and look along the front frame area
- Check the right-hand side of the oven front frame near the drawer opening
- Write down the full model number and serial number exactly as shown
- Include any lot number or letter if you are ordering parts or requesting service
When you search by PLGFZ390ECB, you avoid ordering a part that fits a similar-looking Frigidaire range but has different burner ratings, fuel setup, or hardware.
| What you’re doing | Why it’s better | Example on this model page |
|---|---|---|
| Search by model number | Filters to parts designed for your exact build | PLGFZ390ECB parts list and diagrams |
| Search by part name only | Can return multiple similar parts | “Oven light bulb” may vary by base/type |
| Match by part ID | Confirms the exact item you’re buying | Range oven light bulb 316538904 |
- Match the model number first, then confirm the part name and part ID
- If you are replacing a surface burner component, verify which burner position it fits (front/rear, left/right)
- For gas-related parts (regulator, valve, igniter assemblies), shut off gas and power before servicing
- If you pull the range out to access connections, reinstall it level and check gas connections for leaks (per the installation guidance)
Using the correct model number prevents wrong-part returns and helps your range heat and ignite properly, especially for gas components like burner heads, igniters, and the pressure regulator.

How to replace the igniter on a Frigidaire gas stove?
On the Frigidaire gas range model PLGFZ390ECB, replacing an oven igniter typically means accessing the igniter at the oven burner, disconnecting power, removing the old igniter from its mount, and installing the new igniter in the same position so it can glow and open the gas valve during bake or broil. Use the PLGFZ390ECB installation guide for access and test steps.
- Shut off electrical power at the breaker; the igniter circuit is live when the oven is on.
- Shut off the gas supply valve.
- Let the oven fully cool.
- Remove oven racks for working room.
- Have a nut driver/screwdriver and work gloves ready.
- Remove the oven racks and the oven bottom panel to reach the burner area.
- Locate the igniter mounted at the oven burner.
- Disconnect the igniter wiring connector (or carefully separate the wire connection).
- Remove the mounting screws, then lift off the old igniter.
- Install the new igniter in the same orientation and secure it with the mounting screws.
- Reconnect the wiring, reinstall the oven bottom panel and racks.
When you set the oven to BAKE or BROIL, the igniter should glow like a light bulb; once hot, the oven valve opens and the burner lights. A normal ignition delay is about 30 to 60 seconds.
| What you see | What it usually means | What to do next |
|---|---|---|
| Igniter glows, burner lights in 30 to 60 seconds | Normal operation | Let it cycle once, then recheck temps |
| Igniter glows, no flame after 60 seconds | Gas not opening or weak igniter | Recheck wiring and mounting; consider valve/igniter diagnosis |
| No glow at all | No power to igniter or failed igniter | Check power, connections, and controls |
A properly working igniter is what allows the oven gas valve to open safely; if it’s weak or miswired, you can get no-heat, long preheat times, or intermittent baking.
