1.Ceramic heating ring damaged;
Solution: First, turn off the power of the ceramic heating ring of the heating ring, unplug the wires of the ceramic heating ring, use a multimeter to check whether the ceramic heating ring is burned out, and replace it immediately if it is burned out to solve the problem.
2.No strong current output;
Solution: Check the strong current used in the heating ring of the electric heating ring and the ceramic heating ring, and check with a multimeter. The usual problem is that the heating switch trips or burns out, and the trip is pushed up again from beginning to end. If a fault occurs, turn off the power and replace it.
3.Ceramic heating ring contactor burned out
Solution: First, as a problem with the ceramic heating ring contactor, check whether the control power supply of the ceramic heating ring contactor is live, if live, check whether the contacts are loose, then use a screwdriver to loosen and tighten the connector after turning off the power. The fifth problem with the connector is that the ceramic heating ring contactor is damaged, so it can be replaced. Note to make symbols for each line to avoid unclear recall.
4.Ceramic heating ring contactor has no control power supply;
Solution: When the control power supply is exhausted, there is usually no output power on the 10 board of the computer. There are two fundamental problems. One is that the overload maintenance cable is burned out, and the other is that the output point is burned out, and the thermal fuse is burned out. Replacing the current fuse can solve the problem, but if the output point is damaged, it can only be solved by using a spare output or repairing the 10 board.
5.Ceramic heating ring circuit open.
Solution: Use a multimeter to check the circuit section by section, find the damaged part of the ceramic heating ring and replace it, or make a connection from the beginning.
