I have a question and hoping someone here may have had a similar issue and can point me in the right direction Today I had my guys put in an Amana condenser simple 3ton 16 seer( we are new to the Amana brand 5th one we have put in). Everything went smooth. They ran into such an electrical issue, so I stopped by and found 24v going out to the unit but nothing to the coil it was tripping the pressure switch now mind you, they just opened the valves and added .8 oz the unit would not come on, so I bypassed the pressure switches, and the unit came right on ran for about 5 min then the compressor started making a banging sound is there something I’m missing here it has this little black box that I’m assuming reads amp for the compressor as well as supplying 24v to the contractor coil. I pulled the disconnect. I’m going back a day next week, but I’m just confused as to what it could be if anyone has any ideas, let me know, thanks
