Hi, what is happening is the defrost control board or defrost thermostat has a problem. It works on time and temperature to defrost and its not doing it by or I should say on its own at the times needed. This is why you have to do it manually, to reverse the flow of freon to melt the Ice. You would have to be a qualified service tech to trouble shoot the unit to see if the problem is in the defrost board for timed defrost, or the snap on defrost thermostat for a temperature defrost. If you call a tech out, it will cost you some $$$. What I would do if you want to take care of this, it to call around to a/c places and appliance repair houses and ask what they would charge you if you removed it with some help from a friend or two, and take it in to them. If you do go this route, make sure you ask if its going to set on a bench somewhere for a week before they even look at it also. Make sure they give you a written estimate on parts and labor and compare that to a new unit. I wish I could walk you through this, but there are so many controls to check and you would need a set of manifold gauges to even attemp a repair and to be able to read these to know where to go. I hope that I have given you some direction to go to, and have been of help to you. Please be kind in rating if you will, and I will always be here for any help you may need one way or another. Thanks for using us here at

    After doing some thinking on this unit, it looks like a widow unit, cool only. If its icing up on you you are not getting enough airflow across the indoor coil and it will ice up. Also if the coil is dirty, filter is plugged or the unit has a small freon leaf, it will ice up on you. Clean the indoor coil and wash the foam filter. If that doesn't do it, you are only qualified to do a few things your self. You may have to call out a tech to check the freon. You will save $$$ in the long run.

I have a Whirlpool refrigerator. Model # ET1CHMXKBO3 and it leaks water into the bottom of the refrigerator. Water also freezes on the bottom of the freezer compartment. I checked for a clogged hole o

When your refrigerator defrost the water runs into a drain pan in the bottom/underneath the refrigerator, You will need to first unplug and remove contents from freezer and proceed to remove the air tower in the center of the back panel, underneath the evap. coil in the center is a hole that leads to the drain and it is iced over and the water is not able to flow.What i do is get a hair dryer (be careful not to melt the plastic) and defrost/melt the ice. You will need a towel to start and once you think you have the ice removed get some hot water and pour in the trough to make sure it flow's to the drain pan. When the flow is good put the part's back and make sure the refrigerator is level from side to side and slightly tilted towards the back (front to rear)!

Frig & freezer not cooling enough. Ice forming in back of bottom freezer.

You need to have the defrost cycle checked.( heater, limit stat, timer) If the frig can't defrost air can't move across your coils to cool properly. To temporarily get by until you can get a repairman, use a blow dryer to melt the ice build up. Once melted it will work normally for about 2 days till it freezes up again.

Aprox once a month, this is the second time, the fins and coils freeze up and i have to take the food out and unplug it for the nite to melt the ice, so it will get to zero again

You don't have to wait for a month to do it. Defrosting must be done weekly, to minimize that thick layer of freeze ice. You don't even need to unplug the AC cord, just push the defrost or set the defrost timer. After defrosting the refrigerator cycle operation will be back again.
Thanks for asking.

Tempreture on fridge too high ice build up in fridge mahes noise like a tractor

Your automatic defrost cycle may not be working. Feel the walls inside and if they are hard solid you have ice build up and the fan is hitting the walls or ice making the noise. Unplug your fridge for 2 days and let the ice in the walls melt. Put towels on floor to catch water. Plug it back in and it should run fine for a couple of weeks until the ice builds up again. You have a bad timer and it isn't letting the defrost cycle come on. Defrost cycle are heating elements that melt the ice build up and runs about 10 mins once a day or so. This will give you time to check if an afforable repair can be done or a replacement fridge.

Freezer is defrosting

Many times, on a fridge with automatic defrosting, there is a sensor at the back of the freezer section (behind the plastic) that detects a freeze condition - sometimes these go bad, In normal operation, usually once a day, the timer sends a signal through this sensor and if it shows a frozen condition, it activate a heater (yes, a heater) in the freezer section that melts and defrost the coils. If this system stops working, the ice builds up and closes up the air passages to the fridge section, causing it to warm up, while the freezer section ices up!

Check for icing and maybe try defrosting a little by removing power for a little while. Move any food to another fridge while you are fixing it. The freeze sensors are easy to change, but be careful - electricity can kill. Always hire a professional if you have any doubts about your ability to perform the work yourself.

Sounds like your auto defrost is not running long enough to melt the ice that develops on the coils. You can easily fix this problem by using a hair dryer and removing the back panel in the freezing unit to reveal the coils. Once this panel is out use the hair dryer to melt the ice. Once the ice is cleared this should restore air flow across the coils. Hope this helps. Good luck.

Ice on back wall but not freezing food and rattle noise. Moved all food to other freezer

This is a fairly common problem with these types of refrigerators. The design is set to defrost every 12 hours and be down for 1 hour to allow ice to melt on coils. More often than not the ice never fully melts and creates a blockage in the coils and in turn slows air flow. You can remove the screws in the back wall of freezer unit and unsnap the ice maker plug to allow access to the coil. Gently tilt the back plate forward. You can then unplug the ref. and help it thaw with a blow drier. If you are not comfortable removing the back plate then you can just unplug the ref. and let it thaw on its own. this may take a while. try to remove as much ice as you can from the back of the freezer wall by hand and prop the door open for a couple of hours to ensure that all the ice melts. The rattling sound you are hearing is the fan blades hitting the ice that is built up around it. As a precaution I recommend that these type of refrigerators get manual defrost simply by unplugging about once a month for about two (2) hours. I hope that this will help you out with the melted ice cream. Good luck.

Freezer freezes up causing the refrigerator side not to work

you probably have a bad defrost timer. This item will turn on a hot coil to melt the ice when it needs melted. If you coils are solid ice then the cold air cant travel to the refrigerator side to cool it. This air is moved with a fan and the ice blocks the movement. Melt all the ice with a hair dryer and put the cover back on u will be good for a bout a month and if defrost timer is bad it will clogg again.

Ice forming on freezer

The drain is plugged. This fridge will defrost every 8 hrs or so. When it does , it will melt the frost that has built up on the evaporator. This melted frost will run down a drain under the evaporator to a drain in the bottom directly under the evaporator. When the drain gets plugged the water cannot drain out of the freezer compartment. After several defrost cycles the melted frost will overflow onto the freezer floor. When the fridge starts back up it will freez this water is the bottom of the fridge. sometimes this water that is now ice will melt on the next defrost cycle and actually run out into the floor. You will have to unplug the fridge or turn it off, then remove the cover to the evaporator. Get a hair dryer and melt the ice aruond the evaporator and drain. Once the ice is removed, check the drain and try to clear it. Once clear, replace everything but the shelves. Plug the fridge back in or turn it back on. Observe and listen for the evaporator fan. It should be running now. When working on the ice on the evaporator always be carefull. The defrost heater can be damaged if up push or pull on it too much.

Amana ABB1927DE lower drawers freeze and lock potential

Cold air settles to the bottom of the fridge. Things that can freeze easy may if the door is closed for long periods of time. This is a normal condition for any refrigerator. Look to see if there is a vent that goes to that drawer and close it all the way. That may make a difference.
