Question about Refrigerators

Open Question

AMANA ABB2222FEQ . Found freezer coils iced up and contents of freezer thawed. De-frosted freezer by opening drawer, removing contents, turning off power for hour or so. After ice melted from coils, turned power back on and freezer and refrig operated normally. After noticing frost build up on coils, found instructions for forced defrost using ADC panel. Forced defrost seems to operate properly but cycle seems to end before all frost is gone. I would like to examine the heater and defrost thermostat but am unable to remove back panel of freezer after removing the ice maker and the four screws at the corners of the panel. How does this panel come out? I don't want to force anything.

Geezer, sounds like a defrost issue. I usually find the bi-metal to be the culprit on this model. Check out the pic. You will have to remove the back panel in the freezer and defrost the evaporator. Remove the ice maker if there is one. The back cover has 4 quarter inch screws. remove those. The air vent has 2 plastic clips one each side and one on the bottom, push in and pull the grill off. The thermistor cover has a slot for a flat blade screw driver,push in and pull the cover off. The thermistor will now slide behind the back panel. Check the bi-metal for buldging. As long as the evaporator fan is working, it's probably a defrost problem.

Sounds like your coils are getting plugged,(excess ice in and around the coils)if you have a cooler or some other place to keep your food cold,turn off or unplug the fridge,you want to defrost it,for the freezer place pans of hot water in it to speed up the process,leave doors open,should only take around 4 to 12 hrs.A good time to clean it to lol.

SOURCE: Side by side refrig./freezer does not cold.

Are the heat exchange coils behind or under the refrigerator clean?
Are the fans running smoothly? Check for bent blades and bend them back if necessary.
Is the evaporating pan under the refrigerator dry.? Then the drain of the defroster may be blocked. Unblock with a steam generator or a long plastic tube.

SOURCE: Kenmore Trio bottom freezer frost free. Producing frost

There are several reasons this can be happening...

1. The seal on the door may have a tear or may not be seating properly...this allows excess warm air into the freezer compartment and in its effort to remove the same ...frost appears.

2. There is something call a thermistor (which senses temp and ice build up) that is cycled on and off as needed to remove excess frost accumulation and or ice buildup on the evaporator (freezer) coils...it is a heat strip which actually defrost the frost/ice. If this is not working frost will accumulate and eventually it will become Ice......now the remarkable thing about Ice accumulation is that you would think everything would remain cold or get colder ..however in this case the opposite occurs...it insulates the coils and thereby increasing the temperature...put a thermometer...one that is calibrated properly...(calibration can be set by placing a thermometer into a glass of ice water...the temp of a glass of ice water..after a few minutes setting will be exactly 32 degrees)..if the temperature of your refrigerator is gradually rising over the period of a week...you will need to call a tech or replace the thermistor and or trouble shoot other problems that may have occur such as..

3. The evaporator fan may be going out although they usually make a high pitched whining noise of a whirring noise before they go out...not always and if they are intermittently cycling off then frost would build up...do you always here a fan running when you open the freezer...if so that is good...fan is working...but it may be cycling off at times when no one is aware.
P.S. the odds of it being due to overfilling are slim...I have been in the industry for 35 years and that is what freezers do...which a lot of people don't realize is that freezers don't actually cool anything ..they just remove heat and when you remove all the heat all that is left is cold (like in space) and when heat is removed quickly frost can appear like when you blow your breath on a freezing cold window..then right your name....but I digress...any way..if there was an excess of heat due to a lot of new food in the freezer it would correct itself by one of the processes i mentioned above..and it would never result in Ice..you probably have one or more of the problems I mentioned...evaluate how long its been going on...

4. Thermostat could be out of adjustment..and or not functioning
properly..which would delay or inhibit a defrost cycle..from occurring..unfortunately almost all of these problems require a tech...or a good handyman.

This should lead you in the right direction...if you need help in finding a reputable service company in your area let us know..I hope this has been helpful..if so PLEASE rate me....thank you... .......The Fang

The freezer is warming up


If you found something lodged in the door that may have kept it open for a while, i suspect frost formed on the coils behind the panel. Frost will not let air pass through the coils to the refrigerator side. This is one of the most common problems there is. If you look through the louvers on the rear panel that is for sure your problem. It most likely just needs thawed out. After it is thawed out, your normal defrosting routine will take over again and hopefully you will be trouble free again.

Amana Distinction side by side


When you say flows out of the bottom do you mean on the floor of the kitchen? Not cooling can be a sealed system problem if it happens in both fridge and freezer. The frost build up could be due to low refrigerant levels in the system. If possible, turn off the frige for a few days with the doors open to thaw any problem areas. Remove the lower panel in the freezer section to view the coil area. Turn the unit back on and watch for a "white frost" pattern on those coils. The pattern should be uniform and even across the whole coil area. If the frost suddenly stops on a coil (the rest are not frosted) you likely have a leaky system and a loss of refrigerant. This would be worst case. Unit must have about 17 degrees (or colder) to make ice (with water of course.... Sort of sounds like a couple different problems at the same time.
