If the power is down, turn on a fan, it will be noticeably running a lot slower than with "full" power, be easier if you have a "meter" and can check the actual voltage.

The other two aircons work fine, so I assume we're back to full power. 1 Link to comment Share on other sites More sharing options...
moontang Posted April 13, 2019 Share Posted April 13, 2019 you mentioned "gas" earlier...sounds like it previously leaked, and using it low on refrigerant wears it out at about 5X. It takes a lot more power to start, if it has been abused...capacitator may not be able to deliver enough voltage to start it up. Also, three aircon? with 15/45 service, that could be problematic...the broken one could need 20+ amps to start. Link to comment Share on other sites More sharing options...

Never had 3 aircons running at the same time, not even 2, and not sure I mentioned gas. I did have one in the spare bedroom re-gassed some time ago, but not the one in question here.

The size and age will make a difference but I have been running 5 AC for decades on 15/45 service without issues (although only one normally during day). And have 3x 19CF refrigerators running full time. Link to comment Share on other sites More sharing options...
moontang Posted April 13, 2019 Share Posted April 13, 2019 my mistake,,that was fruitman talking about the gas. Do you have 5/15 or 15/45 PEA service? You can look at your bill and tell..without being able to read thai. Link to comment Share on other sites More sharing options...
madmen Posted April 13, 2019 Share Posted April 13, 2019 1 hour ago, lopburi3 said: Was thinking the above - if unit turned on when circuit breaker turned back on any computer malfunction might not get cleared - wanted to be sure you had actually turned the unit itself off using remote and not just removing electric supply. Guess it time for tech help - good luck getting on hot/holiday/wet evening. I have exactly the same problem after a power cut. Im not getting this. Are you saying turn the AC on and then turn the circuit breaker off ? Link to comment Share on other sites More sharing options...

No. Have the aircon turned off, then turn off the circuit breaker for 15 minutes, turn power back on and start the aircon again to see if it will blow cold or not. Mine didn't.

It will be clearly indicated on front of meter however. 15/45 is standard for most multi room homes. Upcountry bungalows will often be 5/15 Link to comment Share on other sites More sharing options...

You are right, I have had 3-4 air-conns repaired over the years, 1000 baht for a service call and parts. Then run for another couple of years.

kotsak Posted April 13, 2019 Share Posted April 13, 2019 Maybe a case of blown AC capacitor? Link to comment Share on other sites More sharing options...
giddyup Posted April 13, 2019 Author Share Posted April 13, 2019 Thanks everybody for all the tips, but it looks like only the service guy will sort it out now. He's coming in the morning so I'll report on what the problem is. Link to comment Share on other sites More sharing options...
banglay Posted April 14, 2019 Share Posted April 14, 2019 I've had the same thing happen to me twice after a power out rages ....the problem was the starter motor capacitor blow each time ....and had to be replace ( about 700b) ..it only effected one of my 5 units ....the engineer recommended turning the power off to that unit at every outrage ....and turning in back on again a short time after the power is back on ...that way there's not a power peak that can blow the starter capacitor.

Wirejerker Posted April 14, 2019 Share Posted April 14, 2019 When I turn the circuit breaker back on there is a light that keeps flashing on the unit itself and only stops when I use the remote to turn back on, but still no luck. Organised for someone to come tomorrow. Thanks for trying though.That flashing light is probably an error code so if you identify which light and how many flashes or just continuous then look it up and get the man in to fix itSent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...

Yes as has been said, very often power surges will blow the capacitor, which to all intents and purposes could be called a "starter"..........unfortunately there is nothing much you can do about it unless you can get an anti-surge device to protect it and/or possibly the whole system. 1 Link to comment Share on other sites More sharing options...

All I can do when there's a power cut is turn off the breaker for that aircon and turn back on after power has been restored. Link to comment Share on other sites More sharing options...
