r/hvacadvice on Reddit: Daikin error code U0 - 00 on a 4 months old system
September 21, 2024 -
Hey all,
Firstly, I've already written the installers. But seeing it's a weekend, I'm unlikely to get anything back until Monday I recon.
Anyways, in short, today, my (relatively) newly installed Daikin HVAC faulted out, with all internal units spewing a U0 - 00 error. I had a google and it looks like the error is refrigerant related. Which makes me worry if its leaking?
I don't know much about HVAC systems, but how risky is it if this is leaking? its R32 gas in there, is it safe to stay in the property for family (and pets) if there is a possible leak on the system?

r/thermostats on Reddit: Daikin Split AC unit blinking green light, troubleshooting shows no issue
August 2, 2021 -
Hoping to find some help as it is getting majorly hot and humid in my room. I am able to turn the ac unit on and off but it does not open it’s fans to blow any cool air. I did some googling about what to do if the green light on the system begins to blink. First speculation is that it’s a slow blink instead of a fast one that I’ve seen in multiple videos.
I held cancel and cycled through the options, unfortunately, there is no long beep for any possible issue and it cycles all the way to 00 again. At this point I’m not sure what to do or what it might be, because most guides refer back to the troubleshooting table. Any help would be greatly appreciated.

Since you can't get an error code, you can try cycling the main power for the whole AC. Find the circuit breaker, turn it off for a minute or two, and turn it back on. This may clear the error that caused the unit to stop. If that doesn't work, it may be time to call a service technician since diagnosing these things over the internet can be extremely difficult.
