I have a maytag mzd2766ge frigidaire. the freezer work find. until the coil freeze up then there no cold air come in to the refrigidaire until i used the hair dryer to defrost the coil. then the freezer and refrigidaire is cold again. please help!

If sounds like the top cold air tube is frosted up. If you remove the rear shield over the evaporator coil you will see the tube opening. If you use a hair dryer (not of the hottest setting) and blow hot air down the tube you should be able to clear it.
Many times a freezer and/or refrigerator do not work right because of
a dirty condenser coil...there are also many other things that can go
you are hearing a clicking or buzzing then check out the last two
If your refrigerator is running but warm, then...
out these tips that I wrote about that... it is a great place to
start trouble shooting your unit...and something that you can do
rather then calling a repair person to do a simple thing for
Most times this is a bad cold control, but there are other things to check for. Make sure the condenser fan is working and the coils are not covered with dust. A separated heat exchanger ( small capillary tubing soldered to the large suction line ) can separate from one another and make the fridge run too long. - tape tubing back together. A poor working evaporator fan motor could also make the fridge run too long and freeze - replace the fan motor. An inefficient compressor or refrigeration system could make the fridge run too long and freeze - have a service tech check this out. A misaligned control settings, make sure the air damper and cold control have not been bumped and are out of normal settings. Stuck open air diffusers or air dampers are becoming more and more common for allowing too much air to be blown into the fresh food section and freezing things. On all frost free fridge's the freezer temp air is blown into the fresh food section, if you have "easy" to freeze items ( eggs, veggies in water, etc ) in front of or under where the freezer temp air comes out, they could freeze
Check the cold control, and also the air deflector. As you know, the deflector directs the freezer air toward the front of the frig and the rear of the cold control.
There could be several things causing the frig to be cold but not cold enough. First check thermostat control and air control. Both should be set in the middle setting for normal operation.Next check to see if evaporater fan is running in freezer. It should be running whenever compressor runs and circulates cold air inside frig as well as freezer. Next check if condensor fan motor is running. It blows air over condensor coils to remove heat. Last ,check condensor itself for dirty coils. If they are matted up with hair dust,etc. it will cause poor cooling. you can give thorough cleaning with vacuum cleaner. Hope this helps
is it frozen up? do you have any air flow thru the air tunnel from the freeze to the fridge? Check your air flow with the door switch pushed in. also check to see if the damper door opens...
1) if it is iced up you have a defrost problem. most likely a defrost timer. Turn off or unplug untill all the ice has melted off the evaporator back of the freezer..plug back in and it will work fine untill the ice builds up again. if this work you do have a defrost problem.. if not let me know and we can go deeper...
You likely have a defrost cycle failure. The freezer's cooling coils need to be frosty and cold so the air that the fan pulls over them can cool the fridge section. If the defrost cycle fails, the coils freeze up to a block of ice and air flow suffers (fridge is about 55 degrees F). The freezer stays cold only because there's a block of ice in there now... sometimes that cold "sinks" to the bottom and only the food at the bottom stays frozen (and can even freeze food at the bottom of the fridge compartment while the rest is warm). To be sure, you'll need to take the rear interior panel off the freezer back wall and check the coils to see if they are frozen solid. If they are then there's a defrost cycle failure. If they are showing a nice white frosty pattern evenly all over the coils then that's normal and maybe the evap fan (right above the coils) is not blowing air up properly or is not working at all. That fan should run if the compressor is running, etc. the only time it doesn't run is during an actual defrost cycle. Once you find out what condition the coils are in it should be simple to direct you further on the problem.
