My 20 cubic foot fridge dairy upright freezer has started leaking small puddles of water underneath it is only 3 months old

A drain plug is a small hole inside your fridge to allow for moisture to escape. The reason its leaking water is because its not cooling the water to ice or its defrosting the ice to water. make sure the door closes shut and turn it up a bit as it has been very hot recently

you have refrigerant on the floor you need to A&E FACTORY SERVICE @ 1-800-862-9226.
now you can not do it yourself you need a trained technicians to do the work

the motor of the compressor may have tripped on overload protection. Allow it to cool down and then unplug the fridge then plug it back in and try to run it. It should run. Be advised that the condenser coils underneath need to be clean. You should have a strong person tilt the empty fridge while you vacuum and clean all the dust and lint off the coils. Be gentle as these coils are fragile and are easily damaged. Hope this helps.

YOU HAVE TO REPLACE THE CAPACITOR ON THE COMPRESSOR.. THAT WILL TAKE CARE OF YOUR PROBLEM,, YOU CAN ORDER AT TVPARTSANDMANUALS. COM THEY HAVE PARTS FOR APPLIANCES.. THEY ALSO HAVE A UNIVERSAL ONE THAT IS EASY TO INSTALL COMES WITH INSTRUCTIONS.

I would suggest you check with a local appliance parts warehouse. They will also have a service manual that you can purchase that will guide you.

I cannot find a MQU8057AEW in the Maytag library. I did find a MQU2056AEW that is 20 cu ft.

Make sure that the fridge is level. If the drain pitch is not sufficient, this will happen. The solution is cheap too!

puddles of water appear by the bottom of the fridge every now and then why?

all frost free freezers have to defrost the coils. there is a drain pan or cup in the bottom .. if it overflows or it can't drain out you will get puddles check the drain hose and drain cup or pan.. also check to see if you have ice inside the bottom of you freezer that would be a plugged or freezing drain hose..call for services if only 4 months old...

The freezer defrosts every day. the puddle is from that. It is supposed to go into a pan at the bottom and evaporate. You need to look at the pan and determine if it has a hole or the drain hose is leaking somewhere.
