My two year old Maytag Performa bottom freezer refrigerator makes distinct loud noises, intermittently? - maytag performa refrigerator parts

At first I thought it was the ice cream maker, but seems out of the sound. Two or three quick blows, sometimes in the middle of the night wakes me. No sequence with sound, be very unpredictable, day and night. All departments are working well, refrigerator, freezer, ice machine. The block is in his case, the room clean, without any restrictions. I suspect the compressor is the only are capable of such a noise, sit properly on its rubber mounts, so I removed the vibration.
