SamDean Posted September 24, 2015 Share Posted September 24, 2015 i use daiken wall unit in my office. it's worked fine until this week. it's been blowing, but certainly not cold. every couple of hours it will make an awful racket, and spit ice chunks out. i have turned it off for a few hours to let the ice melt. When i turn it back on, i get the same thing. Comments, questions, concerns? Link to comment Share on other sites More sharing options...

itsmylife Posted September 24, 2015 Share Posted September 24, 2015 (edited) Yes you can if you sort of handyman use a water hose spay the coil ( compressor unit ) with water face slope down and with a brush down the dirt slowly downward. until you see no more dirt water came out , after you done come back here and tell me your story OK ! careful not to spray water upwards it will go into the circuit board ok ! do it at your own RISK .

oneday Posted September 24, 2015 Share Posted September 24, 2015 Labor is cheap. Unless you have done it before, hire a company to come clean it. I had my inside unit cleaned the other day, it took some time, they did a good job and it only cost 500 baht. With costs that low why would you do it yourself and possibly screw something up?

johng Posted September 24, 2015 Share Posted September 24, 2015 Naam isn't icing a symptom of low refrigerant ?? SamDean you could if you like a challenge and don't mind getting hot and dirty Turn off electricity to the aircon before starting to disassemble it. clean the inside and outside coils with a chemical like this. I believe its an Alkaline solution, wear eye protection and cover any surface it might splash onto by accident mix 50 50 with water and spray on use an old toothbrush to loosen the filth be careful not to damage the very fragile aluminium fins then spray again with 100 percent clean water...make sure no water gets into anything electrical.!!! Best option as "oneday" already stated would be to get a team of "profesionals" in to clean, check for leaks,repair and top up refrigerant.

craigt3365 Posted September 24, 2015 Share Posted September 24, 2015 We use our ACs quite a bit. We have them serviced for 400B every 4 months or so. And they need it. The gunk that comes out is disgusting. They are here for several hours. Great value to have them do it and so far, they've done a great job. Numchai.

bankruatsteve Posted September 24, 2015 Share Posted September 24, 2015 ^Yeah. We pay 700 baht but that probably includes some travel costs. If the coolant needs a top-up that's included. Anyway... it's the inside unit that needs the periodic cleaning and you're crazy to try to try DIY. Link to comment Share on other sites More sharing options...
Pib Posted September 24, 2015 Share Posted September 24, 2015 Probably low on freon. Over the years whenever I had an A/C ice-up, home or auto, it was due to low freon (i.e, a slow leak). Link to comment Share on other sites More sharing options...

Tonawatchee Posted September 24, 2015 Share Posted September 24, 2015 (edited) Ice coming off the evap coil can be from a dirty coil, dirty filters or low on charge. Edited September 24, 2015 by Tonawatchee Link to comment Share on other sites More sharing options...

Cleaning will improve cooling capacity and make it a lot healthier to boot. take your reading glasses Steve. my comment was in context with icing. of course regular cleaning is important to achieve best efficiency. but when ice forms on the evaporator due to lack of refrigerant you can clean till doomsday without getting a positive result. p.s. i didn't know that aircons are booting Link to comment Share on other sites More sharing options...

What if he had already done what you said without turning the power off? He'd be toast by now and not been able to reply. usually the installation is done that the outside unit gets its power by a relay from the inside unit. but it's still advisable to flip the breaker because somebody inside the home might switch on the unit while the compressor/condenser unit is cleaned outside.

Pib Posted September 24, 2015 Share Posted September 24, 2015 (edited) If it does turn out to be low freon, be sure the A/C tech finds the leak because there is one if the freon is low. Freon don't .disappear/evaporate/etc. from normal day to day A/C usage...a leak causes it to go low. Without finding the leak, in a few weeks to months you'll have the same problem again.

jacko45k Posted September 24, 2015 Share Posted September 24, 2015 Where are you located? There is a Daikin service centre near my house and I arranged them to come service my unit through there. Rather expensive. The guy gave my Mrs his number and now he and his group moonlights after his normal shift and I get it serviced for 400 baht inside and out.

lblake32 Posted September 25, 2015 Share Posted September 25, 2015 Every time I get my (now 1 year old) units cleaned they "top-up" the refridgerant at 500 Bt extra. Why is this always necessary when my car a/c and refridgerator never seem to need topping up ? Just puzzled ! Link to comment Share on other sites More sharing options...
