A hot section is not hot, because the resistance wire has a large number of turns in some places (dense), and a small number of turns in some places (thin), resulting in a large inductive reactance and a small inductive reactance, resulting in a large power and a small power, so a hot section and a period not hot, it is recommended that the user replace.
Due to the increase in transmission resistance caused by the faulty connection of the power supply cable, the fault connection cable can be reinstalled, and the power supply cable and the cable are connected to the cable in parallel, while ensuring that the connection and crimping are correct, the temperature regulator connection is incorrect, the adjustment is incorrect, or the sensor position is incorrect. Wiring position or sensor position needs to be corrected. If the electrical cable is too wet or the power cord is faulty or damaged, the faulty component should be replaced.
