Wolf Induction Cooktop Error Code 150: Coil Temperature... | appliancefaults.com

Technical Background:

The MCU (Microcontroller Unit) on the control board monitors the temperature of each induction coil via a temperature sensor. This sensor is typically a thermistor that changes resistance with temperature. The MCU uses this resistance value to adjust power output and prevent overheating. error code 150 indicates that the MCU is receiving an invalid or out-of-range signal from the coil temperature sensor.

Symptoms:

US homeowners report the cooktop displays error code 150 and the affected burner will not operate. Some may also experience intermittent operation or inaccurate temperature control prior to the error code appearing.

Possible Causes:

Faulty coil temperature sensor
Wiring harness damage between sensor and control board
Loose or corroded connector at the sensor or control board
Defective control board (MCU)
Overheating due to insufficient ventilation
Incorrect sensor reading due to debris or grease build-up

Solution:

1

Disconnect power to the cooktop at the breaker panel.
2

Locate the affected induction coil based on stovetop usage and observe sensor location.
3

Remove the cooktop surface (usually held in place by screws or clips). Be careful not to damage the glass.
4

Using a multimeter, check the resistance of the coil temperature sensor. A typical reading should be between 10k and 20k ohms at room temperature (70-75°F). Consult the service manual for exact specifications.
5

Inspect the wiring harness and connectors for any damage or corrosion. Clean connectors with electrical contact cleaner.
6

If the sensor resistance is outside the specified range, replace the sensor. Order the correct replacement part from a reputable supplier.
7

If the sensor and wiring appear to be good, the control board (MCU) may be faulty and require replacement or repair. This typically requires advanced diagnostics and board-level repair skills.

Safety Warning:

Always disconnect power to the cooktop at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental re-energization. Induction cooktops operate at high voltages, which can cause serious injury or death.

Prevention:

Regularly clean the cooktop surface to prevent grease and debris buildup. Ensure adequate ventilation around the cooktop to prevent overheating. Avoid placing heavy objects on the cooktop surface, which can damage the glass and underlying components.

Expert Tip:

Some Wolf cooktops have a service mode that allows you to view sensor readings and run diagnostic tests. Consult the service manual for the specific procedure to enter service mode on your model. Often it involves pressing and holding a specific combination of buttons on the control panel.

Frequently Asked Questions

•What is the correct resistance range for the coil temperature sensor on my specific Wolf induction cooktop model?
