Can anyone help me identify this part? It's from the compressor start circuit on an Idils freezer. I believe it is taking the place of the start relay but I am not sure. This was made in China. About the size of a penny and I am wondering how it works to engage the capacitor in the circuit. Some pics attached. Thanks for any help! Jon
