Inverter splits modulate the compressor. That needs a healthy outdoor power board, an indoor controller, and a communication pair between them. After a long outage or a generator swing, you may get a dead indoor, a blinking code, or an outdoor that clicks and refuses to start. Those are electronics jobs.
We read the brand’s code, test the room sensor, coil sensor, and the interconnect. A cheap board swap that ignores a shorted compressor or a failed fan module fails again on day two. If the compressor is locked we say so before you buy a card.
Gree, Haier, Dawlance, Orient, Kenwood, TCL and PEL inverters are the weekly stack. We repair boards where the fault is a blown varistor, a dried capacitor, or a drive section we can rebuild. Some indoor displays are only replaced.
Bring a photo of the error and the outdoor model sticker on WhatsApp. Same-day PCB visits in Bahria Town Phase 7 are common because that is where the shop is.
Questions we get on this job
Can every inverter board be repaired?
Many indoor and outdoor cards can. Water-damaged or fully burnt IPM modules are often replace-only. We quote after we see the board.
Will this void a factory warranty?
If the machine is still on manufacturer warranty, use the brand service centre. Cool Planet is an independent crew for machines out of that cover, which is most Bahria house calls.
Is this the same as gas charging?
No. A board fault will not be fixed with refrigerant. We check both so you pay for the right one.
Do you keep boards in the van?
Common sensors and some indoor cards. Outdoor inverter modules are often next-day once the model is confirmed.
