Exclamation goodman heat pump problem

I have a 3 ton goodman split system heat pump that was installed towards the end of summer last year... it cooled great and when it came time to switch it to heat mode it heated great until about a month ago... while in heat mode the suction line gets hot like its suppose to then after a few minutes it changes to just luke warm and finally got ice cold like it was trying to cool... I have checked the wiring connections and they all seem to be fine... what would be causing this?? could it be that the reversing valve has went bad?? what can I do to check the reversing valve? the fact that the line gets hot then gets ice cold, wouldn't that mean the compressor is okay?? thanks so much in advance for help!

Sounds like you should still be under first year warranty. This option is the best choice if you paid for this installation.

If this is not an option...

It seems more likely that you have a refrigerant leak than a failing reversing valve but you can verify that 24 volts is not present at the reversing valve by unplugging it.

Thanks for replying! Ive read that the reversing valve isnt energized in the heating mode and if so wouldnt that eliminate that as a possible problem? What do u think would cause this ? Thank u so very much.

You might have a short between O and R or between O and Y.

I'd measure for 24 volts AC between O and C to prove that voltage is not present but you can just unplug the reversing valve if you do not have a meter.
