Fortunately, it is possible to repair a PCB. However, the task demands correctly diagnosing the problem, repairing tools, and technical knowledge. However, specific circuits must be repaired within a workshop environment and cannot be fixed on-site.
The AC PCB repair cost lies in the range of Rs. 2,000 to Rs. 5,000. The PCB, which is the Printed Circuit Board, is a crucial element of the modern-day AC we use in our homes.
The repair of physical damage should only be done by a trained and experienced professional. In most cases, it calls for remodeling of the board, resoldering of components, and the reballing of conductive traces.
Replacement AC Circuit Board
The circuit board controls the operation of the blower fan motor as your air conditioner runs. The cost to repair this issue is typically between $100 to $800.
Usually, it is a quick fix, but sometimes the failure can be caused by a much bigger problem. The most expensive part of an AC unit to replace and repair is the air compressor.
Changes in the Performance of Your HVAC System
If your HVAC system does not turn on at all or if it heats or cools your property excessively, the control board might be the cause of the problem. A damaged transistor or cut circuit could prevent the HVAC control board from sending the proper signals.
If you overload a circuit, your system will cut off the electrical flow and prevent your wires from overheating or starting a fire. This is usually an issue that an electrician can repair for you and you likely won't need a circuit breaker replacement.
Start with a Visual Inspection
Often, circuit boards deployed in the field are damaged by electrical surges and there are telltale signs on the PCB. Look for a burnt spot, particularly on the power supply module or I/O and connectivity ports. Pay attention to cracked ICs, broken traces, and blown capacitors.
A damaged aircon circuit board can normally be repaired but this requires a well trained technical personnel to do it. However most circuit boards can't be repaired on site. Proper repairing of circuit boards should be carried out in a workshop environment where all test equipment are readily available.
Check the thermostat
You should check if it's been set to the correct temperature and also make sure it's set to “cool”. If the AC settings are not right, it won't turn on. You can also check if the batteries in the thermostat are fresh and replace them if needed.
In the majority of cases, your AC system will return to functioning normally after this breaker reset. It's important to know that this isn't an instant fix and may take up to an hour to get back up and running as normal again.
Less than 50% of the replacement cost: If your HVAC equipment is under 10 years old and the repair bill is less than half of the cost to replace it, a repair is most likely the right choice.
1. Tripped Circuit Breaker: If your AC unit repeatedly trips the circuit breaker, it indicates an electrical problem such as overloading, short circuits, or faulty wiring. While resetting the breaker may temporarily resolve the issue, persistent tripping requires professional diagnosis and repair by an electrician.
Luckily, there are many ways to help maintain your PCBs and repair them on your own. Simple problems you can fix on your own include intermittent loss of power, overheating, non-responsive components, physical damage (including corrosion), and broken circuits.
Examine the circuit board and search for signs such as crushed components, bulges, damaged wires, cracks, misplaced or extra solder, burn marks and scratches that indicate that the board is either bad or requires replacement and professional assistance.
Should I Replace a Circuit Breaker Myself? Replacing an old circuit breaker is a job best handled by a licensed electrician and must only be done with the electricity disconnected. Doing so may require a permit and electrical codes must be strictly observed to guarantee the safety of your home and family.
You can expect to pay around $550 to $970 for labor to install a dedicated circuit. The cost to hire an electrician is usually $50 to $100 per hour for labor, and electricians typically charge more for the first hour, about $150. The labor for installing a dedicated circuit includes: Shutting off power.
However, like any other electronic device, AC PCBs are prone to damage, wear, and tear over time, which can result in system malfunctions.An AC PCB repair will cost an average of Rs. 1,999 to Rs. 3,999, depending on the extent of the repair.
