Frigidaire Induction Cooktop: not heating, temperature gauge malfunction
What is this symptom?
Experiencing issues with your Frigidaire Induction Cooktop not heating properly? If the cooktop powers on but fails to heat cookware effectively, or if the temperature gauge displays abnormal readings, you're not alone. This can result from incompatible cookware, sensor malfunctions, or internal wiring issues. Discover the potential causes and solutions to get your cooktop back to optimal performance.
Important Tips for Frigidaire Models
- Error code E9 is reported as often associated with temperature sensor, IGBT module, or internal control board issues; video walkthroughs suggest checking sensor harness and IGBT as potential causes before replacement.
Possible Causes
Incompatible or improperly detected cookware
How to Identify: Cooktop fails to heat despite selecting power level or temperature; magnet test on cookware fails or cookware is off-center on zone
Part: Cookware recognition sensor/induction coil interaction
Internal temperature sensor or control board fault (sensor misread)
How to Identify: Displays error codes (e.g., sensor fault, irregular temperature readouts, cooktop shuts down due to false overheat signal; error codes relating to sensor, temperature sensor open/short on powerboard indicate this.
Part: Temperature sensor/induction power board or control board
Loose or corroded internal connections to sensor/coil
How to Identify: Intermittent heating, errors clear on reset but recur; symptoms improve after reseating connections in internal service diagnostics.
Part: Sensor harness/internal wiring
Overheating or internal thermal shutdown
How to Identify: Cooktop shuts off or won’t heat after prolonged use or heavy load; may resume after cooldown.
Part: Thermal protection circuit/temperature sensor
Faulty induction coil or powerboard driving coil
How to Identify: Localised zone never heats even with known good cookware; error persists after resets and routine checks.
Part: Induction coil/induction power board
DIY Solutions
Check and Use Compatible Cookware
- Stop cooktop and remove cookware
- Perform magnet test on your pots/pans: magnet should strongly stick to the bottom
- Use appropriately sized and flat‑bottom induction compatible cookware and ensure it’s centered on the zone
Reset Power to Cooktop
- Turn off cooktop at power or breaker
- Wait 1–2 minutes to allow internal electronics to discharge
- Restore power and test zone heating
Next step
Choose the next step for not heating, temperature gauge malfunction
Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.
Most relevant component to inspect
Induction Heating Coil
Generates electromagnetic energy to heat pots and pans directly.
- Typical part-only price

Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Temperature Sensor
Monitors the internal temperature to ensure correct operation and prevent overheating.
Main Control Board
The central brain of the appliance that controls all components, cycles, and timings.
Power Control Board
Distributes and switches electrical power for the appliance's major loads.

- Malfunctioning temperature sensor or gauge
- Control board failure
User Suggested Solutions
-
Inspect and replace the faulty heating element. Disconnect power, remove the cooktop cover, and test the element with a multimeter. If it's defective, replace it with a new one.
-
Check and replace the temperature sensor. Access the sensor via the cooktop's underside, test it for continuity, and replace if it's not functioning correctly.
-
Examine the control board for any signs of damage or burnt components. If damaged, replace the control board after disconnecting power and removing the cooktop.
