b. The sound from
PCB
.
Analysis
It seldom happened! It is critical when the sound from PCB is detected. There must be
the failure of the component used on the PCB and may cause the safety issue.
Remedy
Need to replace it immediately.
Since it is complicated to check all components on PCB, suggesting to replace it with a
new one.
Procedure:
Mark the original assembly and the wire connection information; use the tool to
dis-assemble the defective PCB. Assemble the new PCB to the original position and
re-connect all wires.
B. Poor performance
Poor performance means even when the cavity is operated, the temperature is always higher
then it should be.
a. Gasket on the door
When the gasket on the door does not “seal” the cavity well, the “cold” will escape from the
cavity. As a result, the temperature can’t be lowered and mist will be formed on the internal
side of the glass window.
Analysis
The gasket may be damaged; or it may be aged and become hardened. Or, there is an air
gap between the gasket of the door and the edge of the body.
Remedy
When the air is found, align the position of the door by loosing the screws of the door hinge.
When the gasket is aged or damaged, need to replace the door. It is difficult to replace the
gasket only since the door is sealed by silicon-rubber.
b. Either fan is failure. Or both fans are failure
When either fan is out of function, the temperature inside the cavity can’t be decreased to a
desired level.
It may be caused by the loosed connection of the fan’s wire to the power supply unit; or, the
fan is failure.
Fan wire connection failure
Analysis
Check if the wire connection is loosed.
