Common fault codes for Supor induction cooker maintenance:
E0 internal line fault
E 1 no pot or pot is not suitable for induction cooker.
Overheating protection of E2IGBT power tube
E3 overload protection (generally, the voltage is higher than 253V)
E4 undervoltage protection (generally the voltage is lower than 175V)
The E5 sensor is open.
How to repair the common faults of Supor induction cooker?
E6 furnace surface temperature overheating protection (generally higher than)
1, Supor C 19S04-A-TD050 1T, E4: the resistance of the main board R256 is 470K.
2. Supor C2 1A0 1-TD0525T has no response after starting. Check the fault of D902 rectifier.
3. Supor C 21S 02 shows E2 after 30 seconds, and the dynamometer temperature sensor is open and normal after replacement.
4. Supor 19S0 1-A shows E 1. Check R28 for aging. From 820 thousand to 960 thousand It is normal after replacement.
5. Supor C 19A0 1-B-TD0526T, after starting, the indicator lights are all on and off, and it can't work. Check R8 resistor for 240K open circuit.
6. Supor C2 1A0 1 Induction cooker has no response after starting. Check that the voltage of 15V is not available, and check that the 2M starting resistor on the side panel of the power supply is open.
7. Supor C2 1S02-A (black C)-TD050 1CT, after starting up, E 1 is displayed, and the resistance of R28 increases to 1000K, which is actually 820k. After replacement, it will be OK.
8. Supor c19s07-a-sdbs01-190. After the machine is turned on, the lamp does not check the pot. Check that the resistance of R5 1 is increased from 470K to 520K, and it is normal after replacement.
9. The induction cooker of Supor C 16BS lights up and gives an alarm, but it does not heat-R473 and R55 1, with resistance values of 32K and 220K. 32K for 24K, 220K for 75K.
10- Supor C2 1S 12-A has intermittent heating. 8UF plus 4UF capacitor, it's OK. Or cut off the output pin of R55 synchronous resistor 180K and lead it directly to the input end of J 19, and remove the flying wire of J 19.
1 1- supor c 2 1a 0 1-B-DL02-A0 The E0 of this motherboard is 10K.
