Dometic Duo Therm Penguin 15000 btu kicks 20 amp a/c breaker

Toddupton..my 1st thinking is breaker...feels soft when pulled off and breaker releases instantly when turning to cool..no sounds from fan or compressor, just click of breaker kicking off. With cool off, fan does not run in on position (does not kick out breaker either). No auto fan run either. Don't have tools to check amp draw, but wouldn't be possible ? with instant breaker release.

John...voltage good at 122
