shaemus Posted March 21, 2019 Share Posted March 21, 2019 My AC unit has broken down, The unit failed to start up and i got the local guys out to have a look, the main board has had a chip short out from a ghecko egg which was layed there. I asked the AC guys to order a new board and install it. No response My called the biggest appliance spares store that i know of in Khon kaen. the guy said that they don't make that board any more and we should get it repaired at Amorn. the AC unit is only just over a year old. it is a Samsung non inverter type Has anyone had something similar repaired? Does any one know an online re-seller that i can order a replacement? I have attached photos Thanks in Advance Shaemus Link to comment Share on other sites More sharing options...
lopburi3 Posted March 21, 2019 Share Posted March 21, 2019 Did you contact Samsung? They are likely to be the only source for replacement parts. They don't have parts stores here as in some countries. Link to comment Share on other sites More sharing options...
KarlS Posted March 21, 2019 Share Posted March 21, 2019 Call Samsung - 076 -219-871 Probably best to have a Thai speaker assist. Link to comment Share on other sites More sharing options...

mogandave Posted March 24, 2019 Share Posted March 24, 2019 Getting the board fixed should be much cheaper. Link to comment Share on other sites More sharing options...
Jan Dietz Posted March 24, 2019 Share Posted March 24, 2019 Buck converter is 50 Baht or so, PCB needs a bit of cleaning / fixing up but nothing insurmountable. Looks like they gecko exactly managed to short the Drain and Source pins. Only issue I see is that during the short the full line voltage was available at the output. That may have fried other stuff downstream. https://th.mouser.com/ProductDetail/Power-Integrations/LNK306GN?qs=Jph8NoUxIfVBGCEOQTaDXQ%3D%3D Link to comment Share on other sites More sharing options...
Jan Dietz Posted March 25, 2019 Share Posted March 25, 2019 Here is a local source, for THB 22 it's worth a try. https://www.es.co.th/detail.asp?Prod=019501938 Link to comment Share on other sites More sharing options...

I went to Khon kaen to pick up and the service centre was empty, no Que, and they knew to expect us, the whole process took less then 5 mins. I have fitted the new board and checked the start cap on the head unit to no success. the head unit turns on and then blows air (not cooled) but the outdoor unit doesn't start. the head unit eventually gives up and beeps three times then turns off.

Good that you got the board. Maybe ask Samsung if they can recommend a guy who can fix it for you. Normally the outdoor unit has few connections and not much to check. If you have a millimeter you should be able to check it yourself. You have the circuit plan - see picture above. Maybe its just a bad connection on or near the circuit board.

A new board was purchased from the local Samsung service centre. i installed the board. same as before, i called out the locals lads to have a look. no idea. called samsung Bangkok who then booked a service engineer to come. he scratch his head for a bit and ended up installing a new fan/motor for the compressor. He said he had never seen this before from a Ghecko egg. . Thanks all for your help Shaemus Link to comment Share on other sites More sharing options...

I am pretty sure the problem was a mouse pissing on the top of the PC case which has a lot of holes for ventilation. Unfortunately the mouse pissed on the connectors or the RAM modules. Solution: New motherboard - I am not joking. Link to comment Share on other sites More sharing options...
