Daikin H4 Fault code
Hey all. I'm due at a job in the morning with a Daikin showing a H4. Thanks to this site I found out that it's the Outdoor LP Switch.
Am I ok to loop it out to test to see if the switch itself is faulty?
Thanks

Welcome Eire1.
Provided you put your gauges on to confirm you do not have a lp situation.
Logic would say a quick run would not harm.

Yeah, I'll see what kind of pressure I'm getting. It has to be the gas or switch itself really.
Thanks Grizzly

I hope it's not the PCB. Sure I'll find out in the morning.

Re: Daikin H4 Fault code
No gas in the system at all. Hope this leak isn't too hard to find.
