Induction cooktop fault 1. induction cooktop does not heat.
Fujitsu induction cooker repair method:
Induction cooker in the process of use, if the indicator light is on, the induction cooker alarm is not heated, or intermittent heating, for the use of a long time too long induction cooker, is generally its micro-switch malfunction.
Induction cooker microswitch damage, will lead to induction cooker CPU in the work of the misjudgment, and ultimately the indicator light is on, the induction cooker does not heat; just replace the microswitch and repair.
Induction cooktop fault 2. can not adjust the power during use.
Fujitsu induction cooker repair method:
Induction cooker repair, there has been such a situation, its thermostatic resistor short-circuit, resulting in the induction cooker operating panel of this power adjustment button can not be used, the problem is not big.
Induction cooker repair, the damaged parts need to be replaced; if it is only slight wear and tear, you can continue to use it.
If the main control IC is damaged, it will also make the induction cooker unable to adjust the power during use. It usually appears on induction cooktops with long service life. In the high temperature environment, it will increase the probability of IC damage. Directly replace the IC parts can be. Note that it is the same model.
Fault 3. Induction cooker does not light.
Fujitsu induction cooktop repair method:
Bad key. Check and replace the keypad.
Loose power cord wiring, reconnect power.
If power cord is not energized, reconnect power or replace cord.
Blown fuse, replace fuse.
If the power crystal IGBT is damaged, replace the crystal IGBT.
Resonance capacitor C103 is damaged, so replace capacitor C103.
Silvernier diode, check and replace the silvernier diode.
Bad transformer, no 18V output. Check and replace the transformer.
If the baseboard assembly is damaged, replace the baseboard assembly.
Induction cooktop fault 4. Induction cooktop does not respond.
Fujitsu Induction Cooktop Repair Method:
There is no explosion when the induction cooktop as a whole does not reverse. First take apart the induction cooker, found that the fuse did not burn. Preliminary judgment is that the induction cooker power chip is damaged. The 18V voltage generated by the chip will become 5V after 7805 for the CPU to work. If you can't provide the corresponding voltage, the induction cooker CPU can't work normally.
The chip of the induction cooker needs to be detected whether it is damaged or not, and needs to be handled by professionals; if it is very expensive, it is recommended to buy a new one and not to replace it.
Induction cooktop fault 5. light blinks when putting pot on.
Fujitsu induction cooker repair method:
May be current comparator CT is bad. Change the current comparator CT.
The pots and pans are not correct and standardized, use the correct pots and pans.
IC1, IC6, R501 adjustable resistor is bad, check the corresponding devices one by one, and then repair.
6. induction cooker buzzer sound is very long.
Fujitsu induction cooker repair method:
May be the thermal control switch is bad, thermistor is bad; the main control IC is bad, you need to replace the switch, thermistor and the main control IC.
Oscillator is bad, the transformer is bad; directly replace the oscillator, check or replace the transformer.
If the substrate assembly is damaged, directly check or replace the substrate assembly.
The above is a comprehensive introduction to Fujitsu induction cooktop faults and how to repair Fujitsu induction cooktops today from Xiangyang Decoration. Have you encountered these six common induction cooktop faults? I hope the editor's sharing can help you and wish you a happy life.
