I have an Amana A4TXNWFWW01 and at the top part of the fridge there is two vents. These vent freeze over and the fridge quits working. Does anyone know what is going on?

If I unplugged it for a day or more and thaw it out, it will start working again.

The defrost heater has a defrost limit thermostat ( a small disc with two wires) that is attached to the cooling coil. This defrost limit thermostat is a switch that will open when the coil is warm enough after defrost. If the defrost heater is staying on too long it can create steam which will condense and freeze on the vents after defrost period terminates.

Your fridge may be overheating from an electrical short causing the fridge to go into auto shutdown so that it will not catch fire. You will need to get it checked up in a shop to confirm the suspicion and to get it fixed.

SOURCE: Amana arb2557cw condenser coils freezing, fridge not cooling

There are a few things that it could be. Do you mean the evaparator coil? This would be the coil on the inside of the freezer, the condenser is outside the unit. If the evap. coil is freezing, you could have to much in your freezer blocking air flow. You could also have a evap. fan not running. Check the owner's manual for the location of the defrost timer, it could be bad. The thermostat needs to be checked and set so that it is at a reasonable level. One last thing to check would be the condensate drain. Make sure the drain is not plugged or the line is not plugged. Good luck.

SOURCE: My refrigerator starts to get warm and then my

Good day,
Your on the right track. The defrost system has failed. It is made up of 3 components. The main defrost heater, mounted to the bottom of the cooling coil behind the rear panel in the freezer compartment, the defrost thermostat which is a small round disk with 2 wires coming out of it located in the same area clipped to the top of the coil, and lastly, the timer which is located in the food compartment, on the roof behind and to the rear of the controls.

To test the timer, (there is a small hole to stick a screw driver into it) turn the shaft clockwise until the machine turns off. Wait 45 minutes. If the machine comes back on, the timer is O.K. Replace the defrost thermostat. If not replace the timer.
It is possible the main heater has failed, but it is a rare occurrence.

Have the bootom freezer. what is happening is the freezer works and the top part quits cooling and the fan quits working. we took everythinhg out and transfered to the outside frig. we unplugged the...

if you can hear the fan still blowing but no cold air coming up to fridge section a common problem with bottom mount freezers is the door gets left open and the air ducts freeze up and the air can't blow up to the top.turn the control off in the freezer.remove the top shelf and the door,check to see if there are any screws one on each side of the slide arms,if there are remove them and lift the door up and out,with a hair dryer melt out the ice by blowing the hot air up each side of the back wall,also if the back inside wall of the freezer is covered with ice or like snow then you have a defrost problem but if there's no ice on back wall do what i said and blow the air up the sides of the back wall through the vents until no more water is seen dripping through the vent holes,then turn the freezer back on and check to see if you feel cold air blowing in through the vents in the fridge section,if you feel cold air then you're all set,if not keep blowing the hot air up the sides until it's melted out.let me know what you find,you'll know if the door was left open,ice will be on the ceiling near the light switch and sometimes on the top of the freezer door.
However if fan has quit totally then it will have to be replaced since it is responsible for cooling the upper part of the fridge

The freezer side does not freeze on the top shelf. The refrigerator freezes everything in the bottom but reads 47 degrees and doesn't cool the top shelves. The fan under the fridge runs fine.

Behind the back wall of the freezer about halfway down, probably behind the light bulb (if there is one there) there is a fan. My guess is that the fan isn't working, or is slow. To test, open the freezer door, then hold the door switch closed and listen for the fan.

This fan should be blowing air up the back of the freezer, and send some of the cold air through a vent at the top of the freezer into the fridge. The air then descends through the fridge and reenters the freezer through a vent at the bottom. If the fan is broken, or if the upper vent is somehow blocked or broken, the cold air will enter (rather than exit) the fridge side at the bottom vent. Because cold air tends to descend and warm air rises, the cold air will freeze the stuff at the bottom of the fridge, and the thermostat (at the top of the fridge) will say it is warm.

I purchased a bottom freezer Amana refrigerator when we built our house in 1999. The produce in the vegetable drawer keeps freezing! Everything else in the fridge is fine. Why does this happen?

Usually on bottom freezer fridges, there are two vents at the bottom of the freezer compartment where the cold air goes back into the freezer (cold air enters the fridge through the vent at the top/back of the fridge.)

If the vents at the back of the fridge are covered, the cold air will settle to the bottom of the fridge after it enters, and freeze your vegetables. The problem could be caused by ice build up in the evaporator coil of the freezer section also, but this will probably warrant a checkup from a pro.

One thing that can cause ice to build up inside those vents is moist air seeping in through a faulty door gasket. A thin coat of ordinary Vaseline on the gasket surface can help it make a better seal.

Amana Fridge with bottom Freezer. Freezer is working fine, but the fridge is warm. What can I do?

It most likely means that the air vent from the freezing unit has stuck in the closed position which causes the fridge to not be any where near as cool as it should be and if it is too cold then the vent is stuck in the open position. The vent is controlled by a small sync motor and either the motor has become faulty, the control module is faulty or the vent is iced up, which can be caused by putting too many hot items in the fridge so the steam condenses and freezes the vent in position and then the motor cannot open or close it causing it and / or the control module to become faulty. Other times it is just old age that causes the motor and / or the control module to fail.

In stand alone fridges the answer could be that the cooling panel at the rear is dirty and needs thoroughly dusting / cleaning / unblocking and checking that there is enough space around it to cool properly and that it is not near any heat sources such as an oven, air vent, microwave exhaust, etc.. It could also be caused by a problem that has resulted in a loss of the refrigerant gas and will need regassing by a service engineer. Also check that the thermostat is working correctly, turn it up and the fridge compressor motor should kick in, turn it down and the motor should turn off. Also make sure that the fridge is not iced up, or overloaded, so cool air cannot circulate inside it. Best call a service engineer asap.

Our refrigerator is not as cool as it should be and seems to be getting warmer

In side by sides if the fridge side not working correctly it means that the air vent from the freezing unit has stuck in the closed position which causes the fridge to not be any where near as cool as it should be and if it is too cold then the vent is stuck in the open position. The vent is controlled by a small sync motor and either the motor has become faulty, the control module is faulty or the vent is iced up, which can be caused by putting too many hot items in the fridge so the steam condenses and freezes the vent in position and then the motor cannot open or close it causing it and / or the control module to become faulty. Other times it is just old age that causes the motor and / or the control module to fail. Best call a service engineer asap.

Everything in fridge freezes intermittently

Your vent has and electronic vent controlled by a setting on the control board. The electronic vent or circuit board are most likely the reason for the problem.
