F2 – Power Board Over-Temperature

What Does the JennAir F2 Error Code Mean?

The induction power electronics board has overheated. The cooktop will shut down the affected zone or all zones until it cools. Ensure the ventilation fan beneath the cooktop surface is not blocked by pots, pans, or cabinet obstructions. If ventilation is clear and the error recurs, the cooling fan motor or power board may need service.

When your JennAir Cooktop displays the F2 code, it means the appliance's self-diagnostic system has detected a fault that requires attention. A single power cycle that clears the code is not a reliable fix if the underlying cause has not been addressed.

Common Causes of the F2 Error

Based on our technicians' experience servicing JennAir Cooktops, the F2 code is most frequently triggered by:

• Component failure: A worn or failed internal part — motor, pump, sensor, or control board — is the most common root cause when this code appears repeatedly.
• Blockage or restriction: Debris, lint, or mineral buildup in filters, hoses, or drain paths can trigger this error without any component failure.
• Wiring or connector issue: Vibration over time can loosen harness connectors, causing intermittent faults.
• Control board fault: Less commonly, the main control board may misread sensor signals and generate a false error.
• Installation issue: Improper leveling, restricted ventilation, or incorrect water supply pressure can cause error codes under normal operation.

Step-by-Step Troubleshooting

Before scheduling a service call, work through these steps in order:

1. Power cycle the appliance. Unplug from the wall outlet and leave unplugged for 60 seconds. Plug back in and run a short test cycle.
2. Inspect and clean filters. Locate the filter or trap for your specific model. Remove, rinse, and reinstall.
3. Check hoses and connections. Inspect drain hose, water inlet hose, and any visible connections for kinks, blockages, or loose fittings.
4. Verify installation conditions. Confirm the appliance is level, has adequate ventilation clearance, and water supply pressure is within spec.
5. Run a diagnostic cycle. Many JennAir models support a built-in diagnostic mode. Consult your owner's manual for the key sequence.

When to Call a Professional

If the F2 code returns after completing the steps above, a component has likely failed. Continuing to run the appliance with an active fault may cause secondary damage.

JennAir Support Center technicians carry the most common replacement parts on every service vehicle. In most cases, we diagnose and complete the repair in a single visit.

Repair Cost Estimate

Typical ranges based on our service history:
