Part One: Trouble Code And Trouble-shooting Strategies for Induction Cooktops

Check with the magnetic table tool whether the power terminal is AC 380v. Power phase shortage occurs if any measurement is about 200v. (Measure "ab," " ac," " bc" respectively .)

Measure with Magnetic table tool; forward resistance of 1-2 and 1-3 angles should be 300-400Ω, reverse impassable. Forward resistance of the 2-3 angle should be around 600-700Ω, reverse impassable. 1-5 and 2-7 angles passable. Symmetric upper and lower deviations of 4-5 and 6-7 angles: angular resistance no greater than 10 Ω

Magnetic table tool measurement of 1-2 1-3 angular forward resistance of 300-400 ohms, reverse 2-3 angle forward resistance of 600-700 ohms or so of 1-5 angle 2-7 angle conduction error of 4-5-6-7 angle resistance is not greater than 10 ohms.

Control board failure

Check the small components on the control board for any obvious shedding or damage phenomenon; if not obvious, change the control board to identify whether it is functional or not.

Drive wiring failure

Check for any obvious shedding, disconnection, or measure with a millimeter if 2 terminals are conducting.

Resistance plate failure

Check if there is any shedding, damage, or breakdown in the resistance panel. Or measure if 4-5 and 6-7 are conducting with a Magnetic table tool.

Output transformer failure or wire disconnect

Check for false welding, virtual welding, or wire breakage

Use the submersible current meter to measure the current; whether there is a flash "intermittently heating" when the adjustment does not work.

Heat dissipation fan failure

Measure with a magnetic table tool; an AC fan has a resistance value, and a DC fan has no resistance value.

Check from its appearance for any bulging or cracking; measure its capacity with a magnetic table detection tool if it is rated capacity.

The fan does not work; coil sensor short-circuited.

Check if the fan works properly and if the coil sensor is short-circuited.

Check if the coil sensor opens circuit.

Fan does not work properly, air access blocked, or aluminum plate sensor short-circuited.

Check if the fan of the PCB box works properly, the aluminum plate is short-circuit or the air access is blocked.

Aluminum sensor open circuit

Check if the aluminum sensor opens the circuit.
