Remedy
If yes, fix it. If not, check the fan(s).
Fan failure
Analysis
Detaching the fan wires from the closed-end connector and re-connect it to an independent
12V power supply. If the fan does not work, it is down.
Remedy
Marking the assembly and the wiring information, detaching the defective fan from the
mounting bracket, installing a new fan onto the original position.
c. When the fans, the PCB, or the semi-conductor become aged
Analysis
Both components are still working. However, since the unit has been used for a long
period of time, or because of many other factors, the component in the unit become aged
and its efficiency become lower.
Remedy
Mark the original wire connection of each component, detach the old component and
replace it with a new one. After the re-installation is done, check if the unit becomes a
better performance.
C.
The temperature inside the cavity can’t be decreased at all
.
Both fans are running. But the temperature inside the cavity does not decrease.
The semi-conductor
Analysis
Check if the wire connection of the semi-conductor is loosed. If yes, fix it.
If the connection is good, then there must be the semi-conductor failure.
Remedy
Unless the repairing is operated by an experienced technician, it is not suggest the change
the semi-conductor only since accurate installation is involved. For the reason of “cost
and effectiveness”, suggesting to change the whole cooling module.
Procedure:
Mark all the wiring connection and mounting position, detach the cooling module from the
cooling housing carefully. Attach the new module onto the original position. Reconnect
the wires.
