Re: mitsubishi heavy industry problem
First things first ,do they operate in cool mode , is the eev in the indoor ok.A system that is short of gas will usually experience a loss of duty across the board if all units are operating under the same mode.Turn off the other units and run the two suspects on their own to see how they go .
Check the control wiring and solenoids at branch selectors if the above ideas come up short..
Cheers
StuTool's ? check ! Condom's ? check !
If you can't fix it , f*ck it !!!
