Small Repair

Repair job(1)A09A3957-001In our daily life situation, when

something break down and need to

be repaired, in most of the case it is 

a loose screw or loose connection

kind of very simple fault.

In certain extent, it is true that the

everything break and lost = natural

were ant tear surely eat away its life

though, in the same time if we pay 

reasonable attention such as to give an oil or tighten the screws etc, the things

can last quite long time.  Like my Electric Kettle, it is more than 30 years old.  

In fact, there is little possibility of a Kettle to break down unless switch

it on without a water thence either whole Kettle melted down or burn-out the

heater element.   It’s mean, if we do “Always put only necessary amount of

fresh water and boil” = Kettle was designed to last for ever in this condition.

[]

But a kind of machine which has a motor inside, its vibration often cause a

break down.  The worst was the worn-out of the motor bearing (due to a rack

of care = dust,  and rack of oiling) otherwise,  a component became loose.

Photo on the top is a control board of a motor tool in which you can see an

exploded component called Triac.

The vibration caused a component to come loose and caused a short circuit.

The damaged parts was visible and the repair was simply to replace and fix them.

The photo above is a control board of a back-up battery power supply.  

Right side in the left photo, you can see a yellowish box shaped component

was burnt and exploded.  From the shape and the size, it’s easy to see that it

was the same one in the left side, which said 100mF = It was a capacitor.

Remove the damaged one and test with equivalent component, if the whole

unit works (it’s mean no other component has been damaged), it’s the repair.

In this very case, the damaged capacitor was replaced by the equivalent

capacitor (in the photo right). —– But, if no obvious damage was seen, then

complicated trace and analysis game starts.  It’s mean, this  is not a small or 

simple repair. —– Some time it was called nightmare and often

it is cheaper to buy new one.  😀
