The Induction Cooker Touch Control Circuit Board (2000W) is a universal replacement module designed to restore or upgrade induction cooktops. It acts as the "brain" of the appliance, translating your finger touches into power adjustments for the electromagnetic coil.

Key Features & Functionality

Precision Temperature Control: Allows you to toggle between specific temperature settings (e.g., 60°C to 240°C) or power levels (e.g., 200W to 2000W).

Timer Function: Built-in digital timer (usually up to 3–4 hours) that automatically shuts off the unit once the countdown ends.

Multi-Function Modes: Typically comes pre-programmed with presets for Soup, Stir-fry, Water, Milk, and Steam.

Safety Protections: * Overheat Protection: Sensors shut down the board if the IGBT or coil temperature exceeds safe limits.

Auto-Pan Detection: Stops power delivery if no compatible (ferromagnetic) cookware is detected.

Voltage Flux Protection: Handles minor surges in electricity.

Components Overview

The replacement kit usually consists of two main parts:

The Power Board (Mainboard): Contains the IGBT, bridge rectifier, and large capacitors that handle high-current power.

The Touch Control Panel: The slim board with the LED display and touch sensors that sits directly under the glass top.

Installation Tips

Warning: Induction cookers operate with high voltage and store energy in capacitors even after being unplugged. Only attempt replacement if you have basic electronics knowledge.

Thermal Paste: Ensure you apply fresh thermal grease between the IGBT/Bridge Rectifier and the aluminum heatsink.

Sensor Placement: The central thermistor (temperature sensor) must be in firm contact with the bottom of the glass cooktop.

Wiring: Double-check the polarity of the fan and the induction coil connections to avoid short circuits.
