Examine the temperature controller of the automatic edge banding machine for any abnormalities. If the temperature controller of the automatic edge banding machine is displayed, determine whether the temperature controller's parameters are cooling or heating mode. That is, to determine whether the automatic edge banding machine's set temperature and actual temperature meet the requirements. If the temperature control meter of the automatic edge banding machine does not display, the power supply voltage of the temperature control meter of the automatic edge banding machine must be checked. If it meets the requirements but does not display, the automatic edge banding machine's temperature control meter is broken and must be replaced.

Check to see if the heating contactor on the full-automatic edge bonding machine is closed. If it is not closed, simply use an electric pen to energize the two points of the heating contactor controlled by the automatic edge banding machine and observe the rated voltage of the contactor. At the same time, the 380v contactor pen of the full-automatic edge bonding machine controlling heating is turned on. The heating contactor's 220v contactor pencil, which is controlled by the full-automatic edge bonding machine,
