How do I reset my GE oven control board?
To reset the controls on your GE JB480SM2SS electric range, disconnect power at the home breaker for at least 30 seconds, then restore power and let the control fully reboot before pressing any pads. This clears many display glitches and repeating function codes.
- Turn the range off.
- Switch the range circuit breaker OFF (or unplug the cord if accessible).
- Wait at least 30 seconds.
- Restore power.
- Wait for the display to stabilize, then set the clock if needed.
- Test a basic function like Bake to confirm the control responds.
Your model has a control lock feature that can make it look like the board is “frozen.”
- Press and hold the +/- pads for 3 seconds to lock or unlock.
- Remember: Cancel/Off stays active even when controls are locked.

If a function code repeats after a power reset, the issue is usually not a one-time glitch.
| What you see | What it often points to | What to do next |
|---|---|---|
| Function code returns after reboot | A failing component or wiring issue | Check connections, then schedule service if needed |
| Display goes blank | Tripped breaker or blown fuse | Reset breaker or replace fuse |
| Clock flashes | Power outage or surge | Set the clock and restart cooking function |
For electrical checks, we use a meter and follow safe practices: how to use a multimeter to test electrical parts video
A proper power reset clears the control’s memory and reinitializes the range’s electronics. If the problem returns immediately, it helps narrow the cause to a component, wiring harness, or control-related failure rather than a temporary software state.

What does F350 mean on my GE stove?
On a GE JB480SM2SS free standing electric range, the F350 code points to a problem in the upper cooling fan circuit, most often a blocked fan, a loose/burned wire connection, or a failed fan-related component that is preventing proper cooling.
- Press Clear/Off to stop the alarm; let the range cool completely.
- Make sure nothing is blocking airflow around the back of the range.
- If the code returns during baking or broiling, stop using the oven until the cooling issue is corrected.
- If you recently moved or installed the range, confirm the power cord and rear cover area are not pinched or contacting hot surfaces.
- Review the error code and cooling guidance in the JB480SM2SS owner's manual.
Most F350 situations come down to airflow, wiring, or a fan circuit problem.
- Cooling fan blade obstructed by debris or a shifted panel
- Loose, overheated, or damaged wiring in the fan circuit
- Failed cooling fan motor (or fan not receiving power)
- Control sensing an abnormal temperature rise because cooling airflow is not happening
| Step | What you do | What it tells you |
|---|---|---|
| 1 | Power the range off at the breaker for 1 minute, then restore power | Clears a temporary control fault |
| 2 | Run the oven and listen for fan operation when the oven heats | Confirms whether the fan is running |
| 3 | If the fan is not running, inspect wiring connections (with power off) | Finds loose/burned connectors |
| 4 | If wiring looks good, schedule service for fan/control diagnosis | Identifies failed fan or control |
The cooling fan helps protect the oven control and wiring from overheating. When the fan circuit is not working correctly, the range may shut down and display F350 to prevent heat damage and unsafe operation.

How do I find the model number on my JB480SM2SS?
For the GE JB480SM2SS free standing electric range, the model number is printed on the rating label. You can find that label on the front of the range behind the storage drawer, or on the oven frame or the side of the drawer frame.
Pull the storage drawer out and check these common label locations:
- Front of the range behind the drawer (most common)
- Oven frame (visible with the door open on some units)
- Side of the drawer frame
- Frame area near the drawer opening
Use these steps to avoid damage while you check the rating plate:
- Make sure all controls are OFF and the oven is cool
- Pull the drawer straight out; lift slightly if it stops on the slides
- Use a flashlight to read the label clearly
- Write down both the model and serial number for parts lookup
- Slide the drawer back in evenly so it seats on both rails
The rating label typically includes both identifiers you will need for parts and service.
| Item | What it’s used for | Example format |
|---|---|---|
| Model number | Matching diagrams and replacement parts | JB480SM2SS |
| Serial number | Identifying production run details | Letters and numbers |
Using the exact model number (including every letter and digit) ensures you get the correct GE range parts for your JB480SM2SS, such as an oven rack, bake element, or control components that can vary by revision.
