Freezer door is not closing equally

The door switch or door module is defective. or the door is not fully closed

Sounds like a noisy compressor module.

thermodynamics: pressure differential when warm air cools causing a difference in pressure. after closing a freezer wait until the pressure equalizes usually within 10-15 seconds then reopen the freezer. as far as the gurgling this is normal. it is the drain tube usually a J type tube that prevents warm air from returning into the freezer.

One of two things are probably happening. If you have a distorted, torn, or missing part of a gasket it may whistle when the air in the compartment suddenly shrinks inside the cabinet when the door is closed. Second possibility is that you have an equalizer tube that allows the air pressure to equalize when the door closed. It occurs to me that maybe the fan inside the freezer may have bearings that are in the process of failing and only complain when the fan motor begins to start up after the door has been closed. hope this helps. Good luck!

Find a service mechanic you trust and get that door FIXED.
the ping pong ball is to allow the air pressure to equalize and the door to stay shut. Use only an approved door closer. Federal Law states that a walkin freezer door is to have an emergency escape means. That means what it says for a reason. So no one gets shut inside the freezer! After you fix the structure your problems will be a lot less. If you dont fix the structure then it will be a continual problem.
address other problems only after the "load" on the refrigeration equipment is taken care of.

there is the HV board on the back under a cover . 2 680uf capacitors @ 35v are likely domed instead of flat on the top and are likely hot. replacing these with an equal value will cure the problem. they are in parallel so 1000 and 470uf will cure it. mine was same model except white. local dealer said no warranty. did not call maytag but he indicated it might help. good luck

few causes why freezer is not freezing properly

1. Your refrigerant (freon) is under charge (causes: possible leak along the pipe system)

2. Your motor compressor probably loose compression

3. Gasket (magnetic rubber) in the door of your freezer doesn't close equally

4. thermostat control is malfunctioning

have a technician check those above written

Sounds as if the evaporator fan has shaft play or the blades are out of balance or striking something. When you open the door the pressure is equal but with the door closed the fan needs to push the air through the evaporator and return again and circle through fan again. I think soon would be a good time to unplug the refrigerator and remove the back panel covering the evaporator and fan motor to inspect the fan, shaft play and the evaporator for frost buildup or any obstruction of air flow.

Check the coils and see if there is ice built up on them. If there is you need a new deftost module

The freezer door is relatively light weight, and when the fresh foods door closes, the air has to go somewhere and the easiest escape route is to momentarily pop the freezer door open. The door should close again quickly. If is does not, make sure the freezer door liner is not touching the top or bottom, causing dragging resistance, and make sure that the front leveling legs are raised up so the door closes by it's self when released from a 45 degree opening. Sometimes the hinge side gasket rubs and holds things up also, especially if that area was cleaned. If that is the case, rub a film of wax on the hinge side gasket to lubricate it. Additional weight in the freezer door will also help.
