Brand New Goodman Condensor Wont start
Just found this forum.
I just finished installation of a second 3-ton Goodman 18 SEER Condensing unit.
The first one installed without issues.
The second one is giving me fits. Here's what happens: The unit tries to start, the fan spins briefly, then it sounds like the compressor attempts to start, but doesn't ... then everything stops. This cycle repeats three or four times, then the unit throws a fault code: Red light solid, yellow light flashes four times ... the diagnostics give four possibilities:
1 - Failed run capacitor ... but this is a new unit (hard start kit installed)
2 - Low voltage ... measures solid
3 - Too much liquid refridgerant in the compressor ... I just installed this today with a new evaporator and 15-ft lineset ... the refridgerant shipped in the unit should be ideal for this
4 - Fronzen compressor bearings ... this unit is new ... installed today, Oct 2012 build date.
Any ideas or troubleshooting recommendations?
I'm afraid you won't get answers here.. You would need to call a professional to troubleshoot system...... These systems can be very dangerous and could cause death and or property or equipment damage not including voiding your warrants. Good luck my friend.
Get a pro membership and you may get some answers there...
put a start kit if that dont do it send it back
He states hard start already installed.. Again get a pro to check... Did you ohm it out? Check cap.. What does refrigerant pressures do? High pressure switch tripping? Possible low pressure switch tripping? Bad control board/ defrost board.. Heat pump or ac not specified... Many possibilities get someone out there that know what they are doing...
Please review the AOP Forum rules before posting.
Those rules can be found here.
Cap checks out just fine ... visual and meter.

No trip on either high pressure or low pressure ... those are separate fault codes.
AC .. not heat-pump.
The issue with getting " getting a pro out" is this:
I have lived in AZ for 6 months.
I purchased a home that were functional, but that I wanted to replace (based on old age ... 1984 technology).
I had two failures (on the old, now replaced units) over the past six months ... called a "pro" both times ... one recommended by the neighbor ... the second recommended by the local HVAC wholesale distributor ... both were sloppy .. in style of workmanship and procedure ... I believe that R134a systems should be charged by super-heat/sub-cool ... both these businesses ... licensed/bonded/insured ... charged based on pressures only ... that is not right ... I hope you agree!
My next step is to fully pump the system down (yes, I have the correct tools) and recharge to a minimum state ... then see what happens.
On a positive note ... I was hoping that this forum could provide positive information ... like the automotive industry, there is a wide variety of skill and service-level. My experience with, service-level has forced me down the DIY path.
I welcome any constructive response or direction to a specific solution or local professional that is not a "hack"
Sounds like you know just enough to be dangerous.
I suggest you not go further without getting a pro who is knowlegeable and thorough.
FYI... r134a is not used in residential hvac systems
Im sorry mr moderator im not being a smart ass at all but I had reviewed the rules this is the second notice from a moderator I would like a email or message to specify what im saying wrong..
