Can I look up Frigidaire parts by model number?
Yes. For your Frigidaire electric range model FEFB78DBB, using the full model number is the most accurate way to find parts that fit, because it narrows results to the exact cooktop, oven, and control components used on your range.
Your model number is typically listed on the serial plate. On many Frigidaire ranges, you can find it by opening the storage drawer (some models) or removing the outer lower panel (some models). Confirm the full model number before ordering.
- Look for the serial plate label, not a sticker on the control panel
- Write down the model number and serial number for reference
- Use the complete model number, including all letters
- If the label is hard to read, take a clear photo and zoom in
For model-specific locations and details, use the FEFB78DBB owner’s manual.
Searching by FEFB78DBB helps you match parts to the correct cooking system (ceramic smoothtop radiant elements, oven door parts, switches, and safety hardware).
| What you need | Example part type | Example from this model’s parts |
|---|---|---|
| Burner won’t heat | Surface element or control switch | Range radiant surface element, 6-in 318178110 or range surface element control switch 316436001 |
| Oven door issue | Glass, hinge, handle, latch | Range oven door inner glass (example available) |
| Range won’t sit level | Leveling hardware | Leveling leg |
Model-number lookup prevents ordering a similar-looking part that mounts differently, uses a different wiring connector, or has a different wattage or size. That saves time and avoids returns, especially for radiant surface elements and control switches.

How do I tell what model my Frigidaire stove is?
Your Frigidaire stove’s model number is printed on the appliance ID tag. On the Frigidaire FEFB78DBB electric range, you can usually find that tag around the oven door frame area or behind the bottom storage drawer; once you find it, take a clear photo so you have it for parts lookup.
Check these common locations on Frigidaire electric ranges like model FEFB78DBB:
- Open the oven door and look along the door frame (front frame) on the left or right side
- Pull out the bottom storage drawer and look on the frame below the oven cavity
- Look behind the lower drawer opening on the front frame rail
- If your range has a backguard, check the rear frame area (less common)
For diagrams and model-specific guidance, use the FEFB78DBB owner’s manual.
The model number and serial number help us match the correct Frigidaire parts, including surface element switches, radiant elements, and oven door components.
| Item | Example format | Why it matters |
|---|---|---|
| Model number | FEFB78DBB | Identifies the exact range design and parts list |
| Serial number | Letters and numbers | Helps confirm production run details |
| Product type | Electric range | Ensures you select the right category of parts |
- Use your phone flashlight and take a close-up photo
- Wipe dust or grease off the tag gently with a dry cloth
- Zoom in on the photo instead of trying to read it in place
- Copy the model number exactly as printed (including all letters)
Frigidaire ranges can look similar across multiple model numbers, but parts like a control switch, radiant surface element, or oven door latch can vary. Using the exact model number prevents ordering the wrong part and speeds up troubleshooting.

What are the most common issues with FEFB78DBB?
The most common problems we see on the Frigidaire FEFB78DBB electric range are surface burners not heating correctly, oven bake or broil temperature issues, and door or control problems (like a sticking latch or worn knob switch). Many of these symptoms trace back to a failed element, switch, or door hardware.
- Surface element will not heat or only heats on high: failed infinite switch or a bad radiant element.
- One burner works, another does not: the affected burner’s element or its control switch is typically the issue.
- Oven won’t bake or bakes unevenly: heating circuit problems; on many electric ranges this points to a failed bake circuit or control.
- Broil not working: a failed broil element is a common cause.
- Oven door won’t lock or won’t unlock (self-clean related): door latch parts can bind or wear.
- Door glass damage or heat loss at the door: inner glass can crack or loosen over time.
- Confirm the range has proper power (a tripped breaker can leave the unit with partial power).
- Try a different surface burner setting; note whether it cycles normally or stays off.
- Inspect the radiant element for visible damage (blisters, cracks, burned spots).
- For oven issues, test both bake and broil to narrow the failure to one circuit.
- If the door is misaligned or dragging, check hinge movement and mounting screws.
| Symptom | Likely part category | Example part for this model |
|---|---|---|
| Surface burner not heating right | Surface element control switch | Range surface element control switch 316436001 |
| 6-inch burner not heating | Radiant surface element | Range radiant surface element, 6-in 318178110 |
| 9-inch burner not heating | Radiant surface element | Range radiant surface element, 9-in 316135401 |
| Broil not working | Broil element | Range broil element 316430900 |
| Door won’t lock/unlock | Door latch | Universal/multiflex (Frigidaire) range oven door latch 316405800 |
On an electric range, a single failed switch or radiant element can look like a bigger electrical problem. Narrowing the symptom (which burner, which oven mode) helps you choose the right Frigidaire replacement part and avoid repeat repairs.
For model-specific operating steps, settings, and diagrams, use the owner's manual and the installation guide.
