Frigidaire Induction Cooktop: not heating, temperature gauge malfunction

Professional Repair Guide

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.

Urgency: Medium

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

Easy 5-10 minutes
  1. Stop cooktop and remove cookware
  2. Perform magnet test on your pots/pans: magnet should strongly stick to the bottom
  3. Use appropriately sized and flat‑bottom induction compatible cookware and ensure it’s centered on the zone
⚠️ Safety First: Do not drag cookware across the glass surface to avoid scratches

Reset Power to Cooktop

Easy 5 minutes
  1. Turn off cooktop at power or breaker
  2. Wait 1–2 minutes to allow internal electronics to discharge
  3. Restore power and test zone heating
⚠️ Safety First: Ensure cooktop is cool before resetting

Professional Repairs

Replace Temperature Sensor or Repair Sensor Harness/Internal Wiring

Estimated Cost: $150 - $350

Replace Control Board or Induction Power Board

Estimated Cost: $300 - $600

When to Call a Professional

Internal error codes relating to sensor faults persist after reset
Cooktop zones permanently fail to heat with good cookware
Temperature gauge displays unsupported or erratic data
Visible internal component damage or electrical smell

Preventive Maintenance

  • Use only compatible cookware: Cooktop failing to heat due to poor magnetic detection
    Frequency: ongoing
  • Clean cooktop surface regularly: Debris interfering with sensor detection and surface malfunctions
    Frequency: after each use

Common Issues Reported by Users

  • Faulty heating element
  • Malfunctioning temperature sensor or gauge
  • Control board failure

User Suggested Solutions

  1. 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.

  2. 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.

  3. 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.
