Thank you Sir for your sharing. I'm from Myanmar. Nice to meet you Sir. I'm always watching, giving Like👍 and subscribing on your channel.Sir, I'm also an air-con technical engineer in my country. I want to get a job in Singapore about air conditioning. Now, I'm preparing my necessaries such as English language and diploma. Sir, Could you tell me if your company needed any one employee .Sir I hope you would reply me back. Thank you.

[@donovandavis5310]

I’m a refrigeration technician with extensive knowledge of stepper motors and valve bodies (in fact I have a battery powered valve driver). Just a little curious why you didn’t sand off corrosion from the valve before installing new stepper (eev)? No offense of course 🤝

My valve is making a ticking noise and the code error is u4. I think you solve my problem. What yours opinion? Thank you.

[@robgraham1204]

Hi if you Google u4 it does not mention to check. The eev says Comms issue between indoor and outdoor What made you go to the eev and find that was faulty ??

[@BonMj]

Pressure drop. If U4 communications problems aircon wont run.

I have had a Daikin EcoSwing Smart R32 12K BTU for 6 months. After two days of voltage fluctuations in my house it started to show a defect (U4). Could this problem have to do with the oscillations?

Would like to ask,the error code U4 indicate there is a system communication error and CU is not working at all.The Outdoor CU error L.E.D light/green small PCB also not light up at all.Is it still EEV,or it could be the CU PCB faulty?

[@BonMj]

May outdoor pcb faulty. U can try off the power supply and on back, once on back u can hear tick,tick,tick sound. If got sound may be not the outdoor pcb problem.

Thanks Mr bon for sharing. Just wondering, i know daikin is a very good brand alike all japanese brands.thats what defers from chinese rubbish,the chinese split units they have no eev,guess why when you clamp meter it you find they draw 1/2 the current for the same power.

有时候要自己判断，UO-U4 很接近，之前我同事check 是UO，reset 过后变U4. U4-如果indoor outdoor能走，就要检查其它的。
