Troubleshooting method for slow temperature rise of 高溫箱式電阻爐

(1) First check the power supply voltage and the controller. If both work normally, the fault is generally due to the open circuit of the heating element, which can be checked with a multimeter and replaced with the heating element of the same specification.

(2) If the power supply voltage is normal, but the working voltage of the electric furnace is low, the main reason is that the voltage drop of the power supply line is too large or the socket and the control switch are not in contact with each other, it can be adjusted and replaced.

(3) If the power supply voltage is lower than the normal voltage, and the heating power is insufficient when the electric furnace is working, it may be a lack of phase of the three-phase power supply, which can be adjusted and repaired.
