Questions & Answers
Frequently Asked Questions
Is it better to repair or replace a PC board?
If minor electronic components are burnt, repair is fast and economical. For severely shorted boards, full board replacement is recommended.
What causes an aircon PC board (PCB) to fail or short circuit?
Common causes include electrical voltage surges during thunderstorms, water leaking onto internal circuit boards, component aging, and insect or pest intrusion (such as geckos or ants shorting copper traces).
Can a damaged PC board be repaired, or must it be replaced entirely?
Minor issues like blown fuses, burnt capacitors, or faulty relays on the board can be repaired via micro-soldering. However, if main microprocessors or multiple circuit paths are fried, a complete board replacement is recommended.
What are the main warning signs of a faulty aircon PCB?
Symptoms include continuous blinking error lights on the indoor display panel, the aircon shutting down automatically after a few minutes, the unit refusing to power on, or non-responsiveness to remote control commands.
How long does it take to repair or replace an aircon PCB?
Replacing a PCB with a factory-original module takes about 45 to 60 minutes on-site. Component-level micro-soldering repairs take 1 to 2 business days if the board needs to be serviced at a workshop.
Are replacement PC boards covered by warranty?
Yes, all new original PC board replacements come with a 3-month to 6-month component warranty covering electrical defects.
