GE Café Induction Cooktop Burners Cycling On and Off:... | appliancefaults.com

Technical Background:

Induction cooktops use electromagnetic fields to directly heat the cookware. The main control unit (MCU) manages the power delivered to each induction coil based on user settings and temperature feedback from sensors. Voltage paths are critical: 240V AC input to the cooktop, converted to lower DC voltages for control circuits, and pulsed high-frequency AC to the induction coils. Overheat protection circuits are built in, triggering a shutdown if a sensor detects excessive temperature. The MCU interprets these sensor readings and controls relays to switch the burner on and off.

Symptoms:

The US homeowner observes that one or more burners on their GE Café induction cooktop cycle on and off intermittently when set to the high heat setting. The burner may reach a certain temperature and then abruptly shut off, only to turn back on after a short period. This cycle repeats continuously, preventing consistent high-heat cooking.

Possible Causes:

Overheat protection triggered due to restricted airflow.
Faulty temperature sensor on the affected burner.
Inconsistent power supply from the breaker panel.
Issues with the induction coil itself.
Malfunctioning control board (MCU) relay for that burner.
Improper cookware being used (not induction-compatible).

Solution:

1

Verify the cooktop is level using a bubble level. An uneven cooktop can cause uneven heating and trigger the overheat protection.
2

Check the breaker panel. Ensure the cooktop breaker is fully engaged and delivering the correct voltage (240V AC). Use a multimeter to test the voltage at the cooktop junction box after LOTO.
3

Inspect the cooktop ventilation. Make sure the vents underneath the cooktop are not blocked by debris or objects. Proper airflow is essential for cooling.
4

Test the temperature sensor of the affected burner. Disconnect the sensor and use a multimeter to measure its resistance. Compare the reading to the manufacturer's specifications at room temperature (70-75°F).
5

Inspect the induction coil for any visible damage or signs of overheating. If damaged, the coil may need replacement.
6

Check the wiring harness connecting the burner to the control board. Look for loose connections, frayed wires, or signs of corrosion.
7

As a last resort, consider replacing the control board (MCU). This requires a new board to be programmed.

Safety Warning:

Always disconnect power to the cooktop at the breaker panel (Lock Out/Tag Out - LOTO) before performing any repairs or inspections. Induction cooktops operate at high voltages and can cause serious injury or death if handled improperly.

Prevention:

Regularly clean the cooktop surface and vents to ensure proper airflow. Use only induction-compatible cookware. Avoid placing objects on or near the cooktop vents. Check the cooktop voltage with a multimeter every 6 months.

Expert Tip:

Many GE Café cooktops have a service mode. To access it, simultaneously press and hold the 'Timer' and 'Power' buttons for 5 seconds. This allows you to view error codes and perform diagnostic tests.

Frequently Asked Questions

•What are the resistance specifications for the temperature sensor at 70°F?

Refer to the GE Café induction cooktop service manual for your specific model. Typically, the resistance range is between 10k and 20k ohms at 70°F. A significant deviation indicates a faulty sensor.

•How do I determine if my cookware is induction-compatible?

The easiest way is to check if a magnet sticks firmly to the bottom of the cookware. If it does, the cookware is generally induction-compatible. Also, look for the induction symbol (a coil) on the bottom.

•What is the recommended method for cleaning the cooktop vents to ensure proper airflow?

Use a vacuum cleaner with a brush attachment to gently remove dust and debris from the vents. Avoid using liquids or compressed air, as these can damage the internal components. Clean the vents every 3-6 months, or more frequently if you notice a decrease in heating performance.
