Aircon PCB Board Repair and Replacement.
The PCB controls the fan, compressor, sensors, and display. A board is not automatically bad because the unit will not start. Diagnosis checks the power supply, fuses, relays, sensors, and error codes first. Some faults can be repaired at component level. Replacement is for burned or unavailable boards.

- Buttons or remote not responding
- Burned smell or scorch mark
- Unit turns on and off on its own
The process, step by step
- Get the error code. The technician records the code and the exact behavior, such as a blinking light sequence. The code narrows the fault to a sensor, communication line, or output.
- Check power and fuses. Supply voltage, the breaker, and the board fuse are tested. A tripped breaker or a blown fuse is not a board failure, and replacing the board would not fix it.
- Test sensors and outputs. Thermistors, float switches, relays, and fan outputs are measured. The technician confirms whether the board is receiving good signals and sending power to the right part.
- Repair or source a board. If the fault is a relay, fuse, or cold solder joint, a component repair may be possible. Otherwise, the exact board model is sourced and the old board is kept for reference.
- Program and test. The replacement board is installed, configured if needed, and the unit is run through all modes. Surge protection is discussed if the area has unstable power.
Price table
What the job costs
Indicative Philippine market ranges by unit type. These are not quotes from any listing.
| Unit type | Indicative low | Indicative high | Notes |
|---|---|---|---|
| PCB diagnosis | ₱500 | ₱1,000 | Includes error code reading and output testing. |
| Fuse or relay repair | ₱800 | ₱2,000 | Component level fix when the board is otherwise sound. |
| Component level board repair | ₱1,500 | ₱4,000 | Depends on the damaged section and part availability. |
| Standard PCB replacement | ₱3,000 | ₱7,000 | For non inverter window and split units. |
| Inverter board replacement | ₱5,000 | ₱12,000 | Higher for large capacity or imported models. |
| Surge protector add-on | ₱800 | ₱2,000 | Helps protect the new board from voltage spikes. |
Repair or replace?
- Repair the board if the fault is a fuse, relay, or cold solder joint.
- Replace if the board is burned across several traces or is no longer available.
- A surge damaged board can fail again without protection.
- Ask for the old board back if it is replaced.
How to use the quote
Ask the technician to write the diagnosis, the parts to be replaced, the refrigerant to be used, and the labor charge as separate lines. A quote that only gives one total is hard to compare and easy to inflate.
For a major part, ask whether it is new, rebuilt, or surplus. Confirm the warranty in writing. If the shop cannot explain why the part failed, get a second opinion before approving the work.

Aircon PCB Board Repair: common questions
How do I know if my aircon PCB is broken?
Common signs are a unit that will not power on, a repeating error code, or a fan that runs while the compressor stays off. These signs can also come from a sensor, fuse, or remote. A technician must test the board's inputs and outputs before declaring it faulty.
Can a PCB board be repaired instead of replaced?
Yes, when the damage is limited to a fuse, relay, capacitor, or a cracked solder joint. A repair is usually faster and cheaper than sourcing a rare board. Boards with burn damage across the main circuit or a damaged microcontroller are normally replaced. Ask what was tested and what will be repaired.
Why did my aircon PCB fail?
Voltage spikes, lightning, moisture, insect nests, and poor ventilation are common causes. A board can also fail from age or a shorted fan motor that pulls too much current. If the board burned, the technician should check the motor and power supply so the new board does not fail the same way.
How long does PCB repair or replacement take?
A component repair can take a few hours if the part is on hand. A replacement board may take one to three days to source, especially for inverter or imported models. The installation and test usually take under two hours. Ask for the board model number before paying a deposit.
Is a replacement board original or generic?
It depends on what is available. Original boards cost more and match the unit's programming. Generic or used boards may work but can have different settings or a shorter life. Ask for the brand, model, and warranty on the board, and keep the receipt.

Split Type Aircon Repair
Split systems have an indoor and an outdoor side. Indoor faults show as weak airflow, water leaks, or noise. Outdoor faults show as no cooling, tripping, or a hot compressor. Diagnosis checks both sides before parts are replaced. Typical repairs cover the PCB, fan motor, sensors, drain pump, and compressor.
Aircon Compressor Repair
The compressor is the pump that moves refrigerant through the system. Not every unit that blows warm air needs a new one. Diagnosis checks the capacitor, relay, wiring, power supply, and refrigerant charge first. Replacement is advised only when the windings are open or grounded, or the pump is mechanically seized.
Portable Aircon Repair
Portable units are compact but still have a compressor, fan, PCB, and drain system. Common problems are a full water tank, a kinked exhaust hose, a dirty filter, a weak fan motor, or a control board fault. Some issues are fixed at home. Parts can be harder to source than for window or split units.
