Question about Amcor AMD243HX Air Conditioner
I have 2-zone mini-split ac; 2 indoor model AWM123HX & 1 outdoor model AOM243HX. Bought in july 2009, put in storage and finally installed May 30, 2010. Installed per manufacturer instructions. Pressure tested using nitrogen - no leak. Vacuumed for 10 minutes; vacuum leak tested for 15 minutes - no leak. Opened service valves and ran okay. First 2 days, units were cooling properly. Later, when on cooling mode, P4 flashes about 20 times and then temperature setting return. On auto mode, no P4 flashing but not cooling adequately. Compressor runs for 2 minutes and cycles. I suspect it's lacking 410A refrigerant. What do you recommend?
a 6ya expert can help you resolve that issue over the phone in a minute or two.

these should be seperate circuits so lets forget the condensing unit for a moment. It should not come on because it gets the control voltage for the contactor from the indoor unit. Check your circuit board for a 3 or 5 amp fuse and make sure it hasnt blown. If it has you will get nothing past the board. If that isnt the case, you will have to start checking for supply voltage from the panel to the disconnect at your furnace, disconnect to board(transformer may also be bad) the blower motor. transformer, and circuit board are the only components indoor that effect the outdoor unit.
