The constant temperature electric iron 936 does not heat, and the same is true of the heating core
To this, the main fault should check the temperature control sampling circuit elements such as: to the sampling circuit of the divider resistance breakdown into damage control circuit and chip, each pin to ground voltage is normal if abnormal, abnormal feet around the element can check chip.

After the replacement of the heating core is not heating, this is not the problem of heating core, it should be the temperature control is broken, the heating core is not connected to the power supply
