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 🤝

I love this video! Do you know the impedence for the eev on a 3pcb1412-2 daikin? It has also the brown which is connected to blue 0 ohm. And my readings are strange, different from yours. Red2Orange and Red2white = 45, blue2yellow =24, orange2white=90 and all the rest infinite. Thanks!

The equalizing pressure is over 225psi but the condenser is not starting. I get the error on start up

[@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?

Same problem with mine. Error code U4.

[@reubenbugeja4066]

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.

[@jennylim3447]

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.

U4 不是indoor or ourdoor communications,问题？？

[@BonMj]

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。
