My freezer only freezes at the bottom - Maytag 15 cu. ft. / 425 liter Upright Freezer MQU1556A

The defrost drain outlet is stopped up and freezing over.
Remove the bottom basket.
Turn the freezer off.
Look in the center of the freezer just below the cooling coils in the bottom of the freezer.
You will see a water drain trough.
It will be full of ice.
Use a hair dryer to thaw the ice and remove it.
The drain will become exposed.
It must be thawed also,so that you can pour water through it and the water goes all the way to the drain pan underneath.

it is the fast freeze button,use it when filling up freezer when less than 1/2 full.red is a high temp warning.orange is fast freeze on/working.

The freezer drain is cloged.Drain is in the bottom of the freezer floor in the back you may have to remove back panel. Run wire or somthing down drain tube to clear clog.

There is a fan behind the back wall of the freezer about 1/2 way up from the bottom, you should be able to hear this running when the freezer is on. If you do not hear this then you need a new evaporator fan motor.

If you hear the fan run then you most likely have a problem with the automatic defrost cycle that would most likely be the heat element that is located just below the coils inside the freezer behind the panel.

the drain needs to be check for any kind of blockage. if the drain is blocked or frozen over this needs to be cleared

Short on refrigerant would be a good starting point, pressure temp relationship should be tested by an opperative.

looks like low on freon. that causes freeze up. oddly enough they freeze up when charge is low , just the opposite of what you think they would do. you have a freon leak unfortunately. probably not accessible, and therefore not repairable. i would suggest, cut your losses and buy new. unfortunately for me and all other srevice techs, the days of affordable repair are over, you can now replace cheaper than i can fix and have a warranty and its new... good luck

hi thanks for the question the drain hose leading from the freezer is clogged up remove the ice from the bottom pull fridge from wall find small drain tube clean the tube now it will drain into tray vacuum out while your there thanks the appliance doc

Look for frost build up on back wall at bottom the auto defrost may be out. Check if the evaporator fan is blowing. If not it's stuck by something or needs replaced. If not The sealed system may have a leak or restiction causing it to only work closest to the evaporator i.e. the lower shelf.

when you plug it in do you ear a fan running if not plug the freezer on.and at the bottom of the freezer gently hit were you have a grill sometime the fan motor gonna start running and circulate the cool air if it work keep and eye on it for a few days take care cheers
