Chk-v9.04g Circuit — Diagram _top_

The CHK-V9.04G schematic is structured around five primary interdependent functional blocks. Each block plays a distinct role in converting mains AC voltage into high-frequency electromagnetic energy.

The circuit board is a common, standardized mainboard used in many budget-friendly induction cooktops (often referred to as "China-common" PCB designs). If you are looking at this diagram, you are likely either repairing a dead unit or trying to understand the power delivery of an induction heater.

Reports on this board often highlight specific components prone to failure: Suspected Components No Power / Dead

The MCU analyzes the loading current of the resonant tank circuit via a current transformer or shunt resistor. If an empty pan or non-ferromagnetic material is placed on top, the system drops into standby mode. Common Failure Modes & Troubleshooting Steps chk-v9.04g circuit diagram

: Features inputs for a thermistor (temperature sensor) typically located in the center of the induction coil to provide real-time thermal feedback.

Linear regulation and LDOs

The most common project that fits this specific versioning style is a (often labeled as "CHi-Pgmr" or similar variants in DIY circles) used to program Microchip PIC microcontrollers (like the PIC16F84A or PIC18F series).

Inspect the 5µF filter capacitor and the 0.3µF resonant capacitor for swelling or loss of capacitance. Sensor Errors (E0, E1, E2) Symptoms: Display shows an error code and beeps.
