Advantages of Aircon Circuit Board PCB Repair
Circuit board (PCB) repairing used to be a common practice. However as technology advances, circuit board design gets so complicated which make repairing a challenge. Moreover the aircon servicing market is flooded with inexperience contractors who easily registered their own company. These contractor when face with difficult problem will always recommend to replace instead of repair and some even advise to replace the whole aircon system. The contractor doesn’t stand to lose any profit but not the case for the unknowing customer who sometime pay more than necessary.
Why repair air conditioner circuit board (PCB) instead of replacing new ones? Other than having a newer board which you will not get to admire anyway (inside the air conditioner), I can’t think of any other advantages. On the other hand, I can list a few advantages of repairing circuit board to share.
Repair at Lower Cost
Repair cost could be ½ or ⅓ lower than the cost of replacing new circuit board (PCB). The cost of purchasing a whole circuit board is definitely higher than replacing the components in it. We realised that the high cost in purchasing of the circuit board can led to several cost related problems which are listed below.
The warranty for the new circuit board (PCB) is not any longer than a repaired one. In some cases, the warranty is even shorter. Reasons being the manufacturer who sell the circuit board do not give the aircon contractor any warranty at all! The contractor will have to adsorb the risk hence they are unwilling to provide long warranty period.
It’s common that other component, for example the internal motor, is damage and in turn short-circuited (damage) the PCB. When a new circuit board (PCB) is installed, it will be damage as well. In such cases, the contractor and customer may be log in dispute of who should bear the cost of the new damaged circuit board. If a circuit board is repair, such dispute will be easier to resolve as no high cost is involved in the purchase of new board.
If an inexperience technician diagnosed incorrectly a circuit board problem, they will insist on the PCB damaged even after having the same problem with a new circuit board. This is to cover for the cost for purchasing of the board. Some contractor may seem to absorb the cost but quote higher or more than necessary other repair works which in another way still covers the cost of purchasing the board.
If an aircon circuit board is already obsolete and no longer in production, some contractor may try modifying the system with some other circuit board or components. This type of modification is strongly not recommended as incompatible parts may cause problems like damage to other parts in the aircon and burnt or short circuit of component and wiring. If a circuit board is repaired, the above will be prevented from happening.
Basically when higher cost is involved in purchasing of the circuit board, this will create problems if there are hiccups. To avoid such incidents and some cost saving, we will advise to first get the board repair. If repair is not an alternative then go for replacement.
