MAKING A LOUD CLICKING SOUNDS

Have you made sure it is at least a couple of inches away from wall? It could be the metal rack on the back may be loose, or the feet aren't exactly level... Does it only buzz when cycling?

Check the condenser fan (outside at the rear) and check the coil isn't baking hot. Electronics or board wouldn't cause your symptoms. Check the simple things first!

its a temp alarm

Change the compressor relay.

Is your circulating fan working?
Sometimes they stick and need a shot of WD 40 and then work
it back and forth a little until it wants to take off again. Keep me informed
and PLEASE give a Thumbs Up for the effort. The Raz Shack

If you have the model number you posted under, you are looking at replacing the evaporator fan motor, which would be a part number 4309014 for that Maytag MQU1556A. It is located inside the freezer, behind the lower back wall.

sounds like either your compressor is loose and just rattling or the compressor is off balance and its rolling around inside the seal can.  take a look at it when it is making the noise.   put your hand on the compressor (careful   might be hot)   if it feel like it running smoothly then i would call an electrician cause that kinda puts me out of ideas without being there...  sorry

Good luck

at 6 years old it certainly aint new!
from what you describe, sounds like a compressor fault

IF YOUR FREEZER HAS A TEMP ALARM, USUALLY LOCATED IN FRONT,BOTTOM, RIGHT CORNER, THE TEMP IS PROBABLY ABOVE THE SAFE TEMP FOR FREEZERS, (10 DEGREES) AND SO THE ALARM WILL SOUND.

THERE SHOULD BE A SWITCH IN FRONT TO SHUT OFF THE ALARM UNTIL THE TEMP GETS BACK DOWN TO ZERO. THEN YOU CAN TURN THE ALARM BACK ON.

IF YOU PLUG IN THE FREEZER AND TURN IT ON, IT SHOULD BE BACK DOWN TO NORMAL TEMP (IF IT IS EMPTY) IN ABOUT 24 HOURS. IF IT ISN'T, YOU HAVE OTHER PROBLEMS. CHECK TO BE SURE THE COMPRESSOR IS RUNNING.

Is it a frost free freezer ? if it is it sounds like the evaporator fan motor making the noise
