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

Technical Background:

Induction cooktops use an induction generator to create a magnetic field, which heats the cookware directly. The cooktop's main control unit (MCU) monitors temperature sensors and controls the power output to the induction elements. Voltage fluctuations or overheating can trigger the MCU to cycle the power to protect the components.

Symptoms:

The homeowner reports that the burners on their GE Café induction cooktop cycle on and off intermittently, especially when set to the highest heat setting. The food may not cook evenly, and the cooktop seems to be underperforming.

Possible Causes:

Overheating of induction element or components.
Low or fluctuating supply voltage.
Faulty temperature sensor (thermistor).
Defective induction generator board.
Incorrect cookware being used.
Partial blockage of ventilation.

Solution:

1

Verify the supply voltage at the cooktop junction box using a multimeter. Should read 240V AC.
2

Check for proper ventilation around the cooktop. Ensure no obstructions are present.
3

Inspect the cookware being used. It must be induction-compatible.
4

Using a non-contact infrared thermometer, check the temperature of the induction element after a few minutes of operation on high. If it exceeds the rated temperature (typically around 500°F), suspect a control issue.
5

Disconnect power. Access the main control board. Visually inspect for burned components, especially around the power supply section.
6

Using a multimeter, test the thermistor resistance according to the service manual specifications. Replace if out of range.
7

If all other checks fail, replace the induction generator board.

Safety Warning:

Disconnect power to the cooktop at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures must be followed. High voltage is present inside the cooktop.

Prevention:

Regularly clean the cooktop surface to prevent grease buildup. Ensure proper ventilation by keeping the area around the cooktop clear. Only use induction-compatible cookware.

Expert Tip:

Many GE induction cooktops have a service mode. To access it, press and hold the power button for 5 seconds, then press the top left and bottom right burner simultaneously. This may display error codes or allow for component testing.

Frequently Asked Questions

•What is the correct resistance range for the thermistor at room temperature?

Refer to the service manual for the specific resistance value. Typically, it's around 10k ohms at 77°F (25°C), but it can vary depending on the model.

•How do I identify if my cookware is induction compatible?

A simple test is to see if a magnet sticks firmly to the bottom of the pan. If it does, it's likely induction compatible. Otherwise look for the induction symbol (a coiled wire).

•Where is the main control board located within the cooktop?

The main control board is usually located underneath the glass cooktop surface. You'll need to remove the cooktop from the countertop and then remove the bottom panel to access it. Disconnect power first.
