There are so many reasons that your easy cook induction cooker won't heat up. First make sure that you are using an induction based pan or vessel. Place the vessel at the center itself. Still not heating after all initial checking and troubleshooting. Then the problem will be at the board.
The technique is simple. Check for all the resistors coming from the IGBT (25N120). They may be some five band resistor above several kilo ohms. Check them and replace them. Your easy cook induction cooker will work fine. Check for steps below.
Step 1 - Check for any Blown Parts or print
For that first unplug the induction cooker, unscrew and open the device. Here we'll speak directly to the point.
On the board first you have to check if any printed circuit has blown out. If not then check if any capacitors (3 large black box capacitors) gone faulty. If capacitors are ok, then comes the difficult area.
Step 2 - Check every high value resistors
Look for all those high value high watt resistors. All those resistors will be above several kilo ohms resistance. Check them using a multimeter. In some cases there will be 5 band resistors.
Here in this easy cook induction cooker we have 5 band resistors. First read the colour code from the resistors and find out their values. Then check them if they are correct.
For this induction cooker we found a 30.4k ohms resistor gone faulty. This resistor show some mega ohms when we checked it.
Just replaced this resistor with the same value and watts. Still after replacing that resistor check the others also as there may be multiple faulty resistors.
Step 3 - Check other spares and voltages
Before closing the device, check those transistors and diodes. Next plug in the induction cooker and check for 18 volts and 5 volts at the control area. Beware of electric shock.
Now screw the board, coil and case properly. Your easy cook induction cooker will work fine. But there are many more cases that will cause your induction cooker won't heat up. We'll discuss about all those in our upcoming posts. Please stay tuned

Great. You have a good taste in presenting ideas.
ReplyDeleteI have philips 4928/01 model induction cook top with slow heating problem, generally it use to take 2 minutes to boil 1 and 1/2 cup water and now it takes 8 or more minutes to boil, can you suggest where could be the fault and what to look for?
