Replace the heating element.
1. De-solder the damaged heating element leads and remove it.
2. Replace a new one and solders to PC board properly.
3.
Solder the two leads of heater to the other side of PC board, bend the leads at
right triangle when soldering to prevent short-circuit
After heating element replaced:
1. Measure the resistance value between pins 3 & 4 or pins 3 & 5 or pin 4 & 5. If it
is not
∞, the heating element or sensor may touch the housing ground.
Eliminates the problem first; otherwise, it will damage the PCB
2. Measure the resistance value between all leads to confirm that the leads are
not twisted and that the grounding spring is properly connected.
Soldering iron cord damaged
Test the soldering iron cord
Check the resistance between the pin of the plug and the wire on the terminal.
Pin 1: Black Pin 2: Red Pin 3: White Pin 4: Black Pin 5: Red Pin
The value should be <2
Ω. If it is more than 2Ω or ∞, the soldering iron need to be
replaced.
Note:
The actual wiring mode shall be subject to the circuit diagram, and the color of
lead sheath will not be informed
