Water coming from under door

possible bad water solenoid or blocked line

I would say or ask how is ur defrost timer working as this seems to indicate that ur build up of ice is more than normal hence u have more water build up that should usually be evaporating from the compressor heat and ur drain pan should not be so full. some other things to consider are below:
Freezer /fridge water/ice in fridge and or freezer

Usually due to CONDENSATION due to bad door seals or a plugged evaporator drain line? Can use a soft flexable tubing and very hot water to clean it out. Bad door seals usually need replacement, but u can use a blow dryer and something to pry it closer to the door wall while blowing hot air on to it. To create a seal, to test for bad door seals place a dollar bill in between the door and wall of fridge where it closes. Then slide out the dollar bill with door closed. It should offer some resistance and not be easy to pull out.
Most all fridges have a drain. Look inside your fridge for a "V" shaped channel with a small hole. This hole leads to a tube and a small pan which sits on top of your refrigerator's compressor. The defrost cycle causes water to run into the channel, down the tube, and then it generally evaporates with the heat of the hot condenser/compressor.
However, if that tube is clogged with food crumbs, particles , debris etc, you will have to clear it to get back to a normal mode of operation. A toothpick, pipecleaner, straw or a cotton bud can often do the trick.
Even a frost free freezer will still ice up at times in the areas away from the heated defrost area and the drain line can freeze. This icing causes the pipe work to the compressor to ice over or sweat and cause a puddle. Or if the drainage has frozen over, it will need to be de-iced. ( usually the line is under the freezer bottom plate covering. Towards the back of the unit) And there is another inside the fridge area also.
Give the freezer a good overnight defrost until it's totally clear of ice in addition to making sure the drain is clear to the pan at the back and then restart the freezer.
God is so good: so this is why I give free advice so please thank him not me.

u can test the defrost timer as well

How long have you had the appliance? There could be a fitting that has not been properly tightened, broken or needs a seal.

The problem may not be the value , look under the front of the fridge remove long cover on bottom, you should see the water line that goes into the freezer door and a connector. Disconnect the water line, should be a quick connect and have a cup ready to check the water line and value, place water line from under fridge into the cup and press the switch on freezer door asking for water if water comes out of the water line then the value is opening and you have a frozen line in the door. Please get back with more info, good luck.

There is a drain line that discharges water from the freezer when the defrost cycle kicks in. It will be a plastic tube that runs from the bottom of the freezer to a tray under the fridge. It has come loose or become plugged I always blow air thru the line and make sure it is not loose. You can also get leakage from an ice maker but this problem will usually show up as ice formingin the freezer first. good luck

If you have both ice and water stopping you have a water supply issue.

Water enters under city pressure through an eighth inch supply line.

Start simple and work from there.

If the fridge was moved the line can get kinked. Slide the fridge out and check you have water to it. You can loosen the supply line connection just a little and you should see water leaking. If not it is a plumbing issue in the house. Most likely a the supply line is kinked or possibly someone closed the shutoff valve to the fridge.

OK so we have water to the fridge.

Water comes in and connects to a water filter and then to the door.

If the filter is badly clogged it can cause low pressure to the door and that would cause the problem. Check the filter.

If no go still then check where the water is stopping.

Remove the from cover from under the unit. That is the plastic grate at the bottom of the fridge. It will just pull off but be gentle and take your time so as not to break anything.

Water supply will run through a clear plastic hose. It runs to the filter then to the bottom of the freezer door and up through the door.

You can sometimes see where the water has stopped and clear or replace parts as needed.

There is a connection just before entering the door from the filter. You can loosen that to see if you have water to that point.

If you have water past the filter the problem is in the ice maker and water supply inside the freezer door. Water can leak here, expand, and crack plastic parts easily.

If there is water to the door then you need to dig into that. This gets a little more complex to describe but in short take the ice maker out and check for water supply or broken parts. The problem is probably before the ice maker as your water in the door is not working. This indicates it is not just the ice maker.

Hope this helps.

Take the two lines off the valve and try the dispenser to see if water comes out and if you hear the valve click when you try it. If you hear it but no water comes out then the valve didn't open. There is a screen filter in the line before the valve that can be stopped up. Replace the valve if it doesn't work. If water does come out Your water line could be frozen in the door. You can disconnect the line under the unit before it goes into the door at the bottom hinge. Push the dispenser button and see if it comes out there. If it does leave the door open till it thaws. Covering the opening with a blanket will prevent the loss of cold in the freezer.

If you can't hear the solenoid on the water inlet valve(it's on the back where the water supply hooks up) when you try the water then the water switch on the dispenser is at fault.

If you do hear it Your water line could be frozen in the door. You can disconnect the line under the unit before it goes into the door at the bottom hinge. Push the dispenser button and see if it comes out there. If it doesleave the door open till it thaws.

If it doesn't come out there disconnect it at the water inlet valve and see if it comes out there.

The common thing is the water line hook up to the back of the frige. First find the shut off. It is usually under the sink or behind the fridge. Roll the fridge out slowly so as not to damage line further. Also roll it straight as not to damage floor. Once u turn off the water line listen to make sure the water drip has stopped if it stops thats the problem. The line is very easy and simple to change yourself. You can get the plastic ones or copper one at the home centers.
The water shut off can look like this behind fridge....

or like this if its under sink either way follow the line from fridge to find it.

This sounds like the Maytag bottom mount that has a High Voltage Control Board problem. Does this have the freezer/fridge temp. display/controls on the left hand fridge door? Whats the model number and on the manufacture tag does it something on it like Code:0304 maybe? Let me know I may have an answer I do work on these for a living.
