hi all,
Today I went to check ona 3 year Panasonic Inverter that stopped working after a few minutes in cooling mode.
Heating mode didn't appear to have a problem although it was not as warm as usual (Insufficient refrigerent I guess).
The pressures were a bit low (5-6 Bar in rest, and 23 in Heating mode asking for 30ºC indoor).
But the strange thing was that on cooling mode the pressure rose to 7 Bar (normal) but about the same time it stopped making cool air inside it rose to about 13 Bar. I Think it's a mix of insufficient charge and air (H2O) in the fluid.
As in, low temperature makes water freeze and blocks a capilar or something.
Also, it presented H98 error (Indoor high pressure protection) although strangely the timer light didn't light up, only the beeps (and yes, the light was working fine).
There was signs of leakage but they were small and for it to still have charge after 3 years they're probably micro leaks in heating mode.
We're going to replace all the fluid, with a vacuum of at least 3 hours in between, anyone has any ideas, suggestions?
Thanks in advance.
