The electromagnetic furnace, which is a common product in people's lives, is easier to cook with the presence of an electromagnetic furnace, and it is easier and less gas-intensive. The normal operation of the electromagnetic furnace lies in the replacement of parts such as circuit boards above it, once the circuit boards are broken or unserviceable. So how much for an electromagnetic furnace circuit board? Enterprises that produce electromagnetic furnaces also need to purchase circuit boards for electromagnetic furnaces, which are described in detail in this paper on the price and maintenance of circuit boards for electromagnetic furnaces。
How much is an electromagnetic furnace circuit board
Electromagnetic furnace circuit boards cost $400, $210, $980 and $90 per square metre. (pricing source network, for information only)

Procedures for repair of circuit boards burning igbt or fuses
If the current fuse or igbt is burned, the spare parts cannot be replaced immediately and it must be established that the following other parts will not be replaced in their normal condition, otherwise the igbt and fuses will be burned。
1. Whether or not the current fuse has broken
2. Test igbt for penetration:
Measurement of igbt's “e”, “c” and “g” tripolar penetrations in the tensile array。
A: “e” and “g” poles; “c” and “g” poles, both positive and anti-tests, are not directed (normal)。
B: the "e" pole, with a black pen to "c", with a very high voltage reduction of around 0. 4 v (type gt40t101 is completely out of order)。
3. Measuring the loss of foot of the sensor, in the normal state as follows:
Interceptor sub-blocks were measured about 80 times in the form of mass-use surface retardants; at first, the extreme was zero。
4. Normality of the whole flow bridge (calculated in the tensile form binary:
A: `-' with a chronology pen, +' with a voltage of around 0. 9 v and no display。
B: "-" with a chronology red pen, and a black pen with a voltage of around 0. 5 v at each input end, with no display。
C: + for all forms of "+" in black, which is reduced by approximately 0. 5 v at each of the two input ends and is not displayed。
5. Examination of capacitor c301; c302; c303; heat damage. (if damage has been deformed or melted)
6. Test the chip 8316 for penetration:
Measurement methods: 8316 tripods are measured using a universal scale, requiring no short circuits between 1 and 2; 1 and 4; 7 and 2; and 7 and 4。
7. Whether the heat-sensitive switch protection at igbt is damaged. Tests of poor key action measure whether the cpu mouth is pierced:
Ii. Poor key-buttoning
The cpu extremes and interfaces are measured in the tensile table diode slots, with a voltage of around 0. 7 v, with a chronology pen to the ground, and with a black pen to the `each pole line of the cpu'. Otherwise, it means that the cpu blow。
Iii. Inadequate power
1. Cyclical disk short circuits: electro-sensor mass of test disks: psd factor l = 157°5? H, pd series l = 140°5? H。
2. Normality of the distance between the pan and the coil。
3. Whether or not the pan is specified。
4. To check whether the components are loose and complete。
Check for bad condition after assembly:
No heat: check if the sensor is broken。
Beep after plugging: checks if the temperature switch ends are well plugged。
3. Unable to open: check if the heat-sensitive endpoint is well plugged。
4. No small object detection (no alarm): check the normality of electrical resistance r301 ~ r307。
R301-r302 is 68k
R303 ~ r306 is 130k
R307 is 3. 0 k
5. If the fan does not turn, check if the triodeq2 is burned. (general triode lead heel has been yellowed; measurements can also be made using a spare table diode slot)
Measurement of igbt's “e”, “c” and “g” tripolar penetrations in the tensile array。
How much is an electromagnetic furnace circuit board? Emp circuit boards are priced at square metres, and the more extensive the emp circuit boards are used, the higher the cost of the emp circuit boards, and the specific price impact factors are influenced by branding, quality, etc. When people use electromagnetic furnaces in their lives, they can first be repaired to address the failure of the circuit boards of the electromagnetic furnace, so that the circuit boards of the electromagnetic furnace can work and the electromagnetic furnace can cook properly。
