DAIKIN Aircon Multi Unit - One head unit not working, others are fine. No lights or response

Hi, I have a Daikin multi split system running 3 head units. 2 are working perfectly, The other one suddenly will not switch on via remote control or on/off switch. This happened after a power cut while the unit was on. When the power came back on, the unit was still in the on position (vents open) but there are no lights and absolutely no response to the remote or the units on/off button. It appears like there is no power to this head unit at all. I can't fault find because there are no lights or noise from the unit. I've turned the power off at the box for 30 minutes - no change. Remotes are working fine. Any ideas ??

Check for power at unit . If there is power to unit check for blown fuse on circuit board or bad board .

How to troubleshooting?

First of all, I am not a A/C repairman, but I do repair many other electronic devices. The first thing any repair person will need is a good service manual for the device, and I have found a link to one for you. I went over the site in quite a bit of detail, its a genuine Daikin site and rich with information.

Here is the link, and best wishes!

Can I run a daikin mini split heat pump 3MXS24JVJU with a generaton

It depends on the SIZE of the generator. If your generator is designed to supply 240-volt A/C and handle the FLA (Full Load Amps) rating of your Indoor and Outdoor units, then, YES, of course you can run it with a generator.

Hi, i have 2 daikin air conditioning unit, 1 is working perfectly but when the 2nd is turned on the power light just flashes and nothing happens, any ideas thanks.

The flashes are codes for different problems the unit may have, count the flashes and check your owners manual this will tell you the problem and the solution, or turn the breaker off for 5 minutes and re-start the unit this will reset it the unit should work if the problem start again you will need a service man. hope I was able to help you.

Selector switch (SS1) blinking, unit does not run

Since I don't have enough info to research your particular unit, I have included a link to the Daikin website. You will have to contact them to get an operation manual.
