I have a portable ac unit. When I plug it in my garage gfi outlet and the compressor kicks on it immediately trips the outlet. Fan will run fine prior to the compressor tripping the outlet. When I plug it in to another outlet in my house, I can hear the compressor kick on and then immediately kick off. The fan will continue to run and then it will try to cycle the compressor again but the compressor immediately shuts down again. Thoughts on what this could be?
