Common Signs of Cooktop Control Failure
While the exact symptom wasn't documented for this Jenn-Air unit, electronic control board failures in electric cooktops typically exhibit these warning signs:
- ⚠️ The glass touch-controls become completely unresponsive or register phantom touches.
- ⚠️ Specific surface elements will not turn on, or they turn on but immediately shut off.
- ⚠ Surface elements get stuck on high heat regardless of the chosen setting.
- ⚠️ The appliance continually flashes a fault code (e.g., F-codes) on the digital display.

The technician diagnosed the cooktop with a bad control board.
Importantly, the diagnosis also included testing another component: The thermostat was tested and found to be good.

Repair Intelligence™: Component Testing & Repair Decisions
A confirmed component failure does not automatically mean the customer will proceed with the repair. After diagnosis, the homeowner may need to compare the proposed repair with other considerations surrounding the appliance.
This service event represents a confirmed electronic-control diagnosis followed by a repair-versus-replacement decision:
- Thermostat: Tested good
- Control Board: Diagnosed bad
- Control Board Replacement: Not documented
- Quoted Repair Total: $604
- Customer Decision: Considering appliance replacement
This record contains two useful diagnostic data points from the same appliance: 1 component ruled out + 1 component diagnosed failed. A diagnostic record can preserve both confirmed failures and tested components that were found to be functioning properly, providing more context than recording only the final failed part.

Homeowner Tips
Electronic cooktop problems can involve more than one possible component. Before replacing an expensive electronic component:
- Have the appliance properly diagnosed.
- Test relevant components when appropriate rather than assuming they have failed.
- Obtain the repair estimate before deciding whether to proceed.
- Compare the proposed repair with the condition and expected future use of the appliance.
- Avoid ordering expensive electronic components based solely on a symptom.
In this service event, testing helped establish that the thermostat was good while the control board was diagnosed as bad.
Preventive Maintenance
The available service documentation does not establish what caused this control-board failure or that routine maintenance would have prevented it. For general electric cooktop care:
- ✅ Keep the cooking and control surfaces clean.
- ✅ Avoid allowing liquids to remain around electronic touch controls.
- ✅ Follow manufacturer instructions when cleaning the glass surface.
- ✅ Avoid impacts to the glass cooking surface.
- ✅ Have persistent control or heating problems diagnosed rather than repeatedly resetting or operating a malfunctioning appliance.
