Nanning Haier microwave oven after-sales maintenance hotline service target service defects, customer satisfaction,
According to the fault phenomenon, according to the user, when the stove is turned on, there is an odor and smoke at first. , and then the power is off.
The cause of the fault was that the fuse was blown and the high-voltage transformer was damaged.
Analysis and maintenance of the most commonly used microwave mode heating in general households. If the user has no special instructions, he should first assume that the fault caused by the microwave mode
handle the machine. If there is peculiar smell and smoke in the microwave oven mode, it is usually caused by the high voltage transformer temperature being too high. If the temperature of the high-voltage transformer is too high, it must be because the current flowing through it is too large. If the current flowing through the high-voltage transformer is too large, it may be that the high-voltage transformer itself is partially short-circuited, or it may be that the load of the high-voltage transformer is too heavy. For this reason, the high-voltage transformer and the devices connected to the secondary were checked. The result was that the resistance of the high-voltage transformer became smaller. At the same time, the high-voltage transformer power fuse was replaced, and the microwave oven returned to normal operation.
Fault phenomenon: Microwave heating food often burns.
The cause of the fault is that the furnace cavity temperature limiter is damaged.
Analysis and Maintenance This machine is equipped with a furnace cavity temperature limiter to monitor the temperature of the furnace cavity. When the temperature of the furnace cavity rises to ℃, it will automatically cut off the power supply to the microwave system and stop emitting microwaves. When the furnace cavity temperature drops to the allowable value, it will automatically turn on and continue
heating. The microwave heating of this machine burns food. Burning food means that the temperature in the oven cavity is too high. It is estimated that the oven cavity temperature limiter has lost its protective effect. After replacing the
temperature limiter with the same specification, the fault was eliminated.
Warm reminder: In normal temperature environment, you can only use a multimeter to test the continuity of the temperature limiter, but cannot judge its characteristics. It is recommended to call
to contact maintenance personnel for repair.
