How much does it cost to replace a GE oven control board?
For the GE JKP20BF2BB wall oven, replacing the oven control board typically runs $200 to $600 total. The control board itself is commonly $150 to $300, and professional labor often adds $150 to $300, depending on access, diagnosis time, and local rates.
Typical cost breakdown
Here is what we see most often for an electric wall oven control board repair:
- Control board part: $150 to $300 (new OEM-style board)
- Service call/diagnosis: $75 to $150
- Labor to replace board: $150 to $300
- Total typical repair: $200 to $600
| Scenario | What you pay for | Typical total |
|---|---|---|
| DIY replacement | Board only (plus basic tools) | $150 to $350 |
| Pro replacement | Diagnosis + board + labor | $300 to $600 |
| “No heat” but not the board | Diagnosis + other part | $200 to $500 |
What changes the price the most
A control board quote can swing a lot based on these factors:
- Correct diagnosis (a bad sensor, thermal cutout, or wiring issue can mimic a bad board)
- Whether the oven is a single or double wall oven configuration (more disassembly time)
- Access to the control area (built-in installs can add labor)
- Parts replaced at the same time (for example, a noisy cooling fan)
- Warranty or service plan coverage (reduces out-of-pocket cost)
Before you buy a board: quick checks that often save money
We recommend confirming the basics first, using the JKP20BF2BB owner’s manual for control and troubleshooting guidance:
- Reset power at the breaker for 2 to 5 minutes, then retry BAKE/BROIL.
- Check for error codes and match them to symptoms using GE wall oven error codes.
- Listen for the cooling fan; a failed fan can cause overheating and shutdown behavior.
- Look for heat symptoms: broil works but bake does not (or vice versa) often points to an element, not the board.
Why it matters
The control board is one of the highest-cost electrical parts in a GE wall oven. A fast diagnosis helps you avoid replacing an expensive board when the real issue is a heating element, cooling fan, or an over-temperature safety device.

What are the parts of an electric oven?
An electric oven like the GE JKP20BF2BB is built around heating, temperature control, airflow, and safety components. The core parts include the bake and broil elements, temperature sensing and control parts, the oven door and gasket, interior racks, and the oven light. See the JKP20BF2BB owner’s manual for your model’s exact features and care details.
Main parts you’ll find in most electric wall ovens
- Bake element: provides the primary heat for baking
- Broil element: provides high, top-down heat for broiling
- Oven control (electronic or thermostat): manages temperature and cooking modes
- Temperature sensor: tells the control how hot the oven is
- Cooling/venting system: moves heat away from controls and vents the cavity
- Door system: door glass, hinges, handle, and gasket to seal heat in
- Oven light and lens/cover: illuminates the cavity
- Racks and rack supports: hold cookware at different positions
Examples of model-related parts for GE JKP20BF2BB
These are common components you may see listed for this model:
| Part type | What it does | Example part for this model |
|---|---|---|
| Safety device | Helps prevent overheating conditions | Wall oven safety thermostat WB24T10060 |
| Air movement | Cools the control area during/after use | Range control panel cooling fan WB26T10018 |
| Heating | Provides top heat for broiling | Broil element WB44T10051 |
| Heating | Provides bottom heat for baking | GE range bake element WB44T10031 |
| Accessory | Supports pans and cookware | Range oven rack WB48T10027 |
Why it matters
Knowing the major oven parts helps you troubleshoot faster. For example, no-heat problems often point to a heating element, a safety thermostat, wiring, or the control, while uneven baking can relate to rack position, sensor accuracy, or airflow.
Quick troubleshooting clues by symptom
- No heat in bake or broil: check power supply, control, and safety devices
- Bake works but broil doesn’t (or vice versa): suspect the failed element
- Oven overheats or underheats: sensor or control calibration issues
- Control area gets very hot: cooling fan or venting issue
- Door leaks heat: worn door gasket or door alignment

What does F20 mean on GE oven?
On the GE JKP20BF2BB electric wall oven, an F20 error indicates the oven sensed an over-temperature condition (the temperature rose above the control’s allowed limit). For safety, stop using the oven until you reset power and confirm the cooling and temperature-sensing system is working correctly using the JKP20BF2BB owner’s manual.
What to do right away
- Press CLEAR/OFF to stop the cycle.
- Let the oven cool with the door closed for at least 60 minutes.
- Restore power (reset the breaker) and try BAKE at a moderate temperature.
- If an F code returns after cooling and a restart, disconnect power and schedule service.
- Avoid self-clean until the issue is resolved; self-clean runs at very high temperatures.
Common causes we see with over-temperature errors
These are the most common issues that can drive temperatures too high or make the control think they are too high:
- A failing oven temperature sensor circuit (sensor or wiring)
- A stuck relay on the electronic control that keeps a heating element on
- Poor airflow or a failed cooling fan that overheats the control area
- Door gasket leaks that cause unstable temperature control
- Power issues after an outage that require resetting the clock and functions
Parts that are often involved
| Symptom | What it points to | Example part for this model |
|---|---|---|
| Oven overheats or won’t regulate temperature | Control or sensor circuit problem | Range oven control board WB27T10409 |
| Error appears during long bakes or after self-clean | Overheat protection opening | Wall oven safety thermostat WB24T10060 |
| Control area gets unusually hot | Cooling/venting problem | Range control panel cooling fan WB26T10018 |
Why it matters
An over-temperature condition can damage wiring, the control board, and heating components. Addressing the cause protects the oven’s electronics and helps prevent repeat shutdowns during baking or broiling.
For code interpretation and next-step troubleshooting, we also use the GE wall oven error codes guide alongside the model’s manual.
