I have an old mitsubishi mr slim 1.5hp aircond.

It is faulty. Can run for 15 minutes n suddenly it stop and giving a 14 blinking light.

I found the reason online and ask my ac repair tecnician to look at.

He suggest to just change the indoor unit to other type that can easily find the sparepart. What do u guys think?

1. Change all set, budget around 1.3k
2. Ask other technician to come
3. Change the indoor unit, rm480 for a recond

how old is your unit?

if got budget , change new one.. shopee got lots of cheap branded like york on sale
new one less headache then fixing it if its out of warranty

5 years++. Looking for either daikin or panasonic. Its located at the open hall downstairs.

The copper pipe is in the wall, so upgrading to 2hp or inverter might be an issue if need to hack the wall.

Its so cheap, dont bother repair bro.

Waste money only.

your technician sure is the indoor unit that spoil?

not the outdoor unit?

better change all set jer

less headache when problem arise

if outdoor unit(compressor) is in workable condition

u can sell it about rm50-100

You were saying to just change to a new unit?

He made a bypass i dont know what, and the ac works fine. So he suspect is the indoor unit. He quoted 480 for a recond unit.

Thanks. If i buy a new one, maybe I can send the old one to kampung and use it there.

Change new bro. Dont get conned.

instalment or whatever. Dont go for recond.

What’s the error for? Indoor coil sensor?

Sure bro. Bought a recond before for rm800. Spoilt after a year. Damn.

Not sure. From what i found it can be refrigerant not enuf (but when it work can fell the cold air), unit is short cycling, outdoor fan motor locks up, or the unit has been pumped down for a long time. I dont know what do they mean

I vote change new unit... my Mr.Slim running strong, already 5yrs+

like others said, not worth change recond and get other issue need fix later....
new unit confirm no issue, even have issue also can claim warranty.

Cheers.

Got the link? I go read on my own

Its been 5 year, Idu fault now ... Odu might be soon and no one will know. Yea, some said my ac work for n year and still working but I guess not all ac is the same, even for the same brand. Too many variable, manufacturing, transportation, storage, installation, use, maintenance ... all play a part.

Change the whole unit ... peace of mind.

Page 25. Not the same model though. But i couldnt find mine.

Mine is ms-gh13vc

so which one is the flash pattern?

I have another 2 units and they are still working fine. Hope it will last. Hehe

Make sense. I'll make a survey later

14 times flash.

If i turn off the main switch and wait for 30 seconds before turn on it will work again for 15-20 minutes before flashing.

erm..........i think the aircon repairman is full of crap.

get another one.

i suspect the aircon filter(filter for the refrigerant) might be blocked. need to replace the outdoor refrigerant filter. that part is generic and can fit for any brand aircon

Just call another one and ask him to check that filter?

first step is to check gas pressure and compressor drawing amp. then only can make the conclusion.
if pressure high(higher than normal) and drawing too much amp then likely filter problem.
drawing too much amp will overload the compressor and give that error.

but if pressure low then need to check for leakage in the connection or indoor coil or outdoor compressor leak

Overload of compressor . Or the compressor run kaokao also hard to reach the set temperature.

Try this

Power off 10min then on back. Not the remote But the switch to the AC
Set temperature to 26c. Turn on
Listen to compressor run.
If the compressor turn on then off then on again, then OK.
Look at the hose near the compressor and see if got see ice on the pipe. If got = just refill gas
If the compressor turn on and continue to run until the error come out then off, then possiBle change the relay at indoor unit. Should be a rm10 item

Indoor unit is changeable. Pricing depends on the reseller if cut throat or not. 2nd hand air cond is also not bad. Used 1 hp including outdoor unit only around rm300~400 again u need to know the technician before buying it.

So the safest is just to get a brand new one. Lazada has some good deals if you're into that.

Did exactly like u said. Set to 26, compressor still running after 15 minutes. Straight change to 31, it stops. Change back to 26, compressor run.

lel.......why change it to 31........sure stop la........

your indoor unit sensor working fine la

And the relay works fine too. Means indoor unit is working fine. Outdoor uNit probably fine too.

Now.. do u see frosty pipe?

Cancel, now my unit is working fine. Hehehehe

Bro, thanks for your troubleshooting steps! After i turned off the switch for 10 minutes, n try again, the unit is now working fine! Not sure what was the problem. If happen again, i'll just change to a new one. Cheers!

Where to sell old compressor AC unit?

i sell it to my technician installer actually

experience 2 times with a different installer

for shop..not sure

maybe can try those household electric equipment repair shop

Hi does ur mitsubishi mr slim still working ?
I am facing similar problem. On & off with blinking light.
Technician came & say could be thermostat faulty or relay swith. Yet cant determine the problem. Its been working fine for 20yrs. Now only got this problem. Its still blowing cold air.
Jus dunno why it on & off.

Still working, but depending on its mood. If i turn on the ceiling fan along with the a/c, it will work fine. But see la, if no luck, it will turn off.

My mistu mr the slim same problem after 5 years +... PCB board fried....my technician bypass the board. Can ON but cant control the temperature. Damn cold....

I just leave it be. But in ther future if ppl want to rent the place ill get it replaced with an inverter unit.

Today mine had this problem .

When the compressor kicks in not more than a minute , Ac shuts down
and 14X blinking light

Model : ms-gh10vc

Fan motor turning in IDU?
Sometimes fan motor failed will cause speed sensor to read 0, means epic fail so auto shut down

Flash light and not cold ke? Then the aircond turn off itsef?

Last time me also got this issue, just change the outdoor unit. Now gooding.

Check the outdoor unit motor whether it produce any loud sound. My case a while ago, the blade motor was loud and suddenly at one point, it stop. Changed the motor and fill up the gas and it working fine till now.

outdoor unit fine

it will shut off when compressor is building up pressure

lol ktard so kaya and straight say recond no good. My recond acson already 10 years still strong. I just change the kipas and it is still in good condition.
