Midea induction cooker display fault code E4, how to repair?
Yes, this can find them after saleMidea's small appliances are guaranteed
Check the resistance temperature sensor, generally about 50K, the other is to check the resistance of 330k and 4 micro capacitance method
The SF164/174/184/194/204/214 model of Midea cooker is..:E04 circuit breaker (heat sink sensor bad)E4: furnace surface temperature sensor open;Beautiful SY191E4 IGBT tube thermistor open circuitE---4 range surface temperature sensor open or low temperature protection
Midea induction cooker shows E4, which means the voltage is too low, that is, the undervoltage protection of the circuit (usually voltage below 175V).Methods of inspection are as follows:1, remove the circuit board, power on, detect the main control IC (U4) sixteenth foot voltage is 2.52V,.2, if the voltage is normal and fault has not ruled out Kai, the main IC damage itself.3, replace the main power on test machine, troubleshooting.4, if the voltage measured by the first step not normal, check with a multimeter, D1, D2, R11, R226, Z2, C203 is normal as long as one of the components of the Kang problems will cause voltage protection circuit, the damaged components removed, changed the same specifications on the components. Start normal Kai troubleshooting.5, if the above components are no problem, then you can confirm that the main IC damage, after the replacement of the fault can be ruled out.
