Compressor was not working

Open back cover and check thecomprosser and ffan. Fan was working and compresore was very hot and freon pipes are not cold. Check the connectivity with the resistor meter on compressor and all 3 pin were checked out ok. that means compressor is ok. Then check overload relay and there was a short butn out. take the part # and order from partselect and i got in 3 days costiing me less than $ 20.00. replaced relay and frezzecompressor start colling the syatem.
