In a lot of restaurants and food service departments will use a lot of high-power induction cooker products, especially for a lot of shabu shabu type of catering will use more of this kind of products, this kind of products will inevitably appear in the process of using a variety of problems, so the operators need to master some of this induction cooker products maintenance methods, can better solve the malfunctioning induction cooker equipment. Induction furnace equipment, so you can better ensure the normal use of these products, to ensure the guarantee of the working effect, and reduce the cost of replacing the new induction furnace. So what is the high-power induction cooktop repair like?

High-power induction cooker repair

One, the circuit board burns IGBT or fuse repair procedures current fuse or IGBT burned out, can not immediately replace the part, you must confirm that the following other parts are in a normal state can be replaced, or else, the IGBT and the fuse will be burned out again.

1. Visualize whether the current fuse is blown

2. Detect whether the IGBT is broken: ? With a multimeter diode gear to measure the IGBT "E"; "C"; "G" between the three poles of the breakdown. A: "E" pole and "G" pole; "C" pole and "G" pole, positive and negative test are not on (normal). ). B: multimeter red pen to the "E" pole, black pen to the "C" pole has a voltage drop of about 0.4V (model GT40T101 three-pole full pass).

3. Measure the transformer is broken foot, the normal state is as follows:? With a multimeter resistance gear to measure the secondary transformer resistance of about 80 Ω; primary pole 0 Ω.

4. Check capacitors C301; C302; C303; whether heat damage. (If the damage has been deformed or melted)

Two, the key action is bad? With a multimeter diode file to measure the CPU pole and the ground terminal, there are about 0.7V voltage drop, the multimeter red pen connected to the "ground"; black pen connected to the "CPU each pole port line". Otherwise, the CPU port line breakdown.

Three, the power can not be reached to the requirements

1. Coil disk short circuit: test the inductance of the coil disk: PSD coefficient for the L = 157 ± 5 μH, the PD series for the L = 140 ± 5 μH.

2. Pot with the coil disk distance is normal. 3. ?3. Whether the pots and pans are specified pots and pans.

4. Check whether each element is loose and complete.? Inspection of bad condition after assembly:

1. No heating: check whether the transformer is broken foot.

2. Plugged in the long beep: check whether the temperature switch terminals are well connected.

3. Can't turn on the power: Check if the thermistor terminal is well connected.

4. Fan does not rotate: check whether the transistor Q2 burned out. (Generally burned transistor pin heel has yellowed; can also be measured with a multimeter diode file).

High-power commercial induction cooker some simple problem repair method summary

Circuit board burn IGBT or fuse repair procedures current fuse or IGBT burned, can not be immediately replaced with the part, you must confirm that the following other parts are in a normal state to be replaced, or else, the IGBT and the fuse will be burned out again.

1

1)Visualize whether the current fuse is blown

2)Detect whether the IGBT is broken: ? Use a multimeter diode gear to measure the IGBT "E"; "C"; "G" between the three poles whether the breakdown.

A: "E" pole and "G" pole; "C" pole and "G" pole, positive and negative testing are The "E" and "G" poles; the "C" and "G" poles, tested positive and negative, do not conduct (normal).

B: multimeter red pen to the "E" pole, black pen to the "C" pole about 0.4V voltage drop (model GT40T101 three-pole full pass).

3) Measurement of the transformer is broken foot, the normal state is as follows:? With a multimeter resistance file to measure the secondary transformer resistance of about 80 Ω; primary pole 0 Ω.

4) rectifier bridge is normal (with a multimeter diode file test):

A: multimeter red pen connected to the "-", the black pen connected to the "+" has a 0.9V or so of voltage drop, reverse no display.

B: The red pen of the multimeter is connected to "-", the black pen is connected to the two inputs respectively, there is a voltage drop of about 0.5V, and there is no display when adjusting the opposite.

C: the multimeter black pen to "+", the red pen were connected to the two inputs are about 0.5V voltage drop, reverse no display.

5) Check capacitors C301; C302; C303; whether heat damage. (If the damage has been deformed or melted)

6)Detect whether the chip 8316 breakdown:? Measurement method: using a multimeter to measure 8316 pins, requires 1 and 2; 1 and 4; 7 and 2; 7 and 4 can not be shorted between.

7) IGBT at the thermal switch insulation protection is damaged. Detection of poor key action measurement of the CPU port line whether the breakdown.

So friends through the above introduction of these points to determine their own induction cooker where the problem occurs, so that after the repair is to get more help from it, so for this type of induction cooker product problems are the need for people to be more detailed grasp of the repair process, to better help the friends through their own is a very good problem to these faults to make a good solution, faster, more efficient, more effective, and more efficient. A good solution, faster and higher quality to complete the repair of these problems. The above is about the content of high-power induction cooker repair, I hope to be able to help you!
