    Fridge Amana AB 2225PEK y. 2006 220v- 50Hz. Freezer at the bottom. Defrost problem ? A lot of ice on the evaporating system. I melted the ice manually a week before - comes again. I replaced the thermostat - didn't help. Heater has 125 Ohm imp, so I guess it is good. Where is the timer (if there's any) and how I force the defrost manually to check if the problem solved? This fridge has a 2 Led's control panel.

    Make sure the evaporator fan motor in the freezer is running, should hear it with the freezer door open. Make sure no build frost build up on the evaporator coils blocking the air flow....those are 2 common trouble makers!

    If so trace the tube that runs down to the bottom of the fridge. If blocked up not draining the lower part of the fridge will stay warm and the freezer will work just fine

    Frost free fridge freezers are very popular and auto defrosting fridges are a great convenience. In a frost free appliance the cold air is blown round the freezer using a fan. On modern refrigeration the evaporator (which is the plate that gets cold) is hidden behind the plastic wall inside at the back of the food shelves. When working correctly you can usually see small beads of ice randomly scattered on the back wall unless it's in a defrost cycle when you may see water.

    Heater inside


    Believe it or not most modern refrigeration has a heater inside. This heater is used to defrost the appliance automatically. During the defrosting cycle the ice on the back wall melts and runs down the back wall into a channel. It is then directed through a hole out through to the back and runs into the evaporator tray. The evaporator tray is on top of the compressor which gets pretty hot and evaporates this water into the air.

    Because the evaporator is behind a back panel the cold air has to be blown around the compartment with a fan motor. The defrost cycle also needs sensors and a timer and combined with several sensors throughout and PCBs to control everything the result is there is a lot more to go wrong than there used to be in old-fashioned conventional fridges. However, they are still fairly reliable.

    Common problems with frost free fridge freezers


    If the door is left open for too long (especially in humid conditions) the evaporator freezes over and the unit will not keep the food cold. This problem (unlike the older machines) has a greater impact because you can't see the amount of ice built up around the back of the panel hiding the evaporator. In many frost free fridges the ice can form all the way round the fan and cause it to run slowly or even seize up. Prior to seizing up the fan may catch on the ice and make a high pitched noise. This will of course result in the fridge or freezer not getting cold. If you hear a strange noise from your frost free fridge freezer which sounds like something is catching on a rotating fan it could be due to ice forming around it.

    If it stops working due to ice forming behind the evaporator and round the fan then defrosting the unit manually can fix it but it involves unplugging the unit for at least take 12 hours or so. You may not see much frost as it would be behind the back wall or behind the fan unit. You can't really use a hair dryer on modern units because they may have a thermal fuse which protects the defrost cycle. Also, even just getting to the evaporator to defrost it can be a mammoth task especially with some of the new American-style fridges. If a fault re-occurs later it could be due to faulty sensor but if the fault was only due to the door been left open for a few hours accidentally then a total defrost could work.

    Whilst we are on with American style frost free fridge freezer's, because the door's are so big and can store so much, the opportunity to overload them is greater. This too causes warm air to pass into the unit and frost it up. Remember a frost free unit will not cope with too much ice on the evaporator so greater care must be taken to use it correctly and check the door seal's regularly.

    Water or sheet of ice inside fridge

    If your fridge has two sloping channels at the back wall and a hole in the middle this is designed to channel the water created on the defrost cycle through to the back of the unit where it runs onto an evaporator tray. This tray sits on top of the compressor and gets quite hot. The water simply evaporates. Sometimes this hole gets clogged up and prevents the water running out to this tray. The result is that water runs into be base of the unit. Very often the appliance will come with small tool for cleaning out this hole, but if not you can improvise.

    If the water in the base of the unit is frozen solid it could be that the unit has malfunctioned and is over freezing. The blockage preventing the water running through to the evaporator tray could actually be solid ice.

    Summary

    It's common knowledge that most people rarely read the instruction book supplied with their new appliance. This is particularly true with something like a fridge or freezer. It's easy to imagine most people thinking you only need to plug it in, leave it plugged in, and fill it with food - what's to know?

    I would advise anyone with a modern refrigeration appliance, especially the American-style fridge freezers, to carefully read the instruction book. Modern frost-free refrigeration units work very differently to a conventional fridge or freezer. It's even important to learn how to stack them properly otherwise you can prevent the air from circulating inside and cause warm spots.

    You would be surprised at what you can learn from reading the instruction book.

    Many User instruction manuals can be downloaded here. The page concentrates on washing machine manuals but links to appliance manufacturer sites where users such manuals for fridges, freezers and other appliances should also be available.

Hello,


Welcome to FixYa.


Based on your post the issue quite likely is the control unfortunately. It is very common for your make and model of fridge.


Here's the method to force the unit into defrost to verify if the control is indeed faulty. (Having a clamp on ammeter here speeds the process since you can see immediate amperage draw, but you'll know soon enough)


The forced defrost function is performed using the refrigerator display and keypad. Enter the Forced Defrost Mode by performing the following sequence of events:

1. Hold the refrigerator door light switch closed.

2. Press the Refrigerator Temperature Down keypad 3 times consecutively.
Note:
The 3 keystrokes must be consecutive and within 10 seconds.

**I also have the complete service manual for this unit, if you think you'd be better served that way, post your email here (only I will see it) and I'll fire it off to you.**

Let me know how you make out or if i can assist you further and I'll do what I can going forward. Good luck.

Regards,

Macmarkus :)

    Hello again,

    The "F" and "D" are only indicating the unit was entered into a "Forced Defrost". If nothing happened you will need the control board. The part number is W10206638 and retails for around $75 at places such as "repairclinic.com" or "searspartsdirect.com" to name a couple.

    I've also sent the email with the pdf attached. I only ask that you take a moment to rate the solution I provided and accept my solution if you find it is correct. (though I may know it is from experience, you may need to see the proof I expect) Good luck.

    Regards,

    Macmarkus :)

I have an Amana (ABB2524DES) bottom freezer fridge. The fridge is not cooling but the freezer seems fine. I just took the back cover off and the fan is working. I cleaned everything and put it back...


Its defrost problem, the freezer should cool, then freeze, then defrost cycle should start. In your case freezer is cooling, then freezing, but its not defrosting. That's why fridge section is not cooling.-------

Wont cool


Hello,
you didn't specify if it is the fridge or freezer that is not cooling. Whichever the case maybe, I would diagnose both the fridge and freezer.
Let's start by diagnosing the freezer;
Fan problem is one of the most common reasons for the freezer to start failing, this is called "frost free failure." Ice can build up on the evaporator coils over time, and this ice builds up until it starts blocking the fan. The fan is responsible for circulating cold air throughout the freezer, so if it is blocked the freezer will not be able to freeze any food. You can usually check this by removing an access panel in the back of the freezer to inspect the coils. If ice is built up on the coils, a hairdryer can assist in defrosting them.
It's also possible that the fan is not running at all. If the fan is burned out or the motor isn't running, cold air can't circulate through the freezer and everything will melt. You can normally hear the fan motor switch on and off from time to time. Listen for it and if you can't hear it coming on for an extended period of time, the motor may need repair or replacement. The wires connecting to the fan may be the problem, preventing the fan from receiving electricity.
Several other problems could be keeping your freezer from freezing:
There could be leaks in one or several of the hoses in the refrigerator, which results in the cold air being lost instead of circulating properly throughout the fridge and freezer.
If you have the freezer so full that the cold air can't circulate, your food will thaw even though the freezer isn't malfunctioning. Always leave some space open in the freezer and try to not store food right up against the cooling vents.
The thermostat might have shorted out, which means the freezer can't accurately determine how cold it is. If this is the case, the refrigerator would probably not be working, either.
If your defrost drain becomes clogged, the water in the line will just refreeze over and over again, which could damage the lines as well as the fan. Always check the drain and make sure no sludge is building up in it if you have a self-defrosting refrigerator.
Always try to keep the freezer door closed for long periods of time. The more the door is opened, the more warm air is let in and cold air is released. If the door is opened frequently, the freezer could be warming faster than the fridge can cool it, which will thaw your food.
As for the fridge, the same solution but for more details. If refrigerator is not cooling properly can be due to a defrost timer, which is causing the fridge to go into defrost cycle. Usually it takes 45-60 minutes for refrigerator to come out of defrost cycle. If the timer goes bad then it will not come out of defrost cycle and can result in this kind of issues. It can also occur due to defrost thermostat, it allows current to pass through it at temperatures of 20 to 30 degrees Fahrenheit and prevents current from passing through it at 40 to 60 degrees. This is difficult to test, though, because it takes a prolonged, very-cold temperature to turn it on. The defrost thermostat is snapped onto the top portion of the evaporator. The thermostat sends temperature information to the processor. The defrost heater must be replaced when replacing the thermostat.
1. Remove the lower fan duct work from the evaporator cover. 2. Remove the 1/4-in. evaporator cover screws and remove the evaporator cover. 3. Disconnect the defrost thermostat wiring connector. 4. Remove the defrost thermostat from the evaporator.
I hope the above helps.......
Good luck.

Model # bx2255w Amana Refridgerator bottom freezer works but refridge isn't cooling any more. Is it time to retire our approx 15 year old fridge or is there an easy fix?


If you have high humidity or the door gets opened a lot, the evaporator coil may need a good defrosting. There are defrosting devices in the unit like the timer, heating coils, thermostats that could be bad. There should also be a small fan in the freezer that transfers the air to the refrigerator section. If that's not spinning only the freezer will work.

If you find the fan and it's working you can do a thorough manual defrost by removing the food, unplugging the unit and letting it set for a day with the doors wide open. Have some big towels handy :)

After a day, plug it in and see what it does (don't add food, yet). If it cools down then you will know that the compressor is still good and it's worthwhile to fix.

Easy fixes: Timer and fan.
Moderate fix (cheap part - more labor) - Defrost thermosat
Pain in the **** fix: Defrost heaters.

Freezer is cold, but cold air is not circulating in refrigerator


Check freezer fan is working.If ice formed over freezer fan by working. It's a common problem due to irregular defrosting. Keep freezer setting temp at 5 degree. And check defrost timer, thermostat,heater are working properly.
Turn timer with small tip screw driver to shut off fridge. If not shut off, replace timer. Turn counter clockwise defrost thermostat. If fridge not shuts off replace defrost thermostat.Check heater by join the 2 wires in the defrost thermostat. And after 1 minute, unplug power and keep your arm on heater. If it's warm heater is o.k. Otherwise, replace heater.
Once heater starts work at regular interval controlled by thermostat and timer, defrost will be good and effective cooling will also be in fridge compartment.

I have an amana fridge model # arb190rcw.nothing remains frozen in the freezer.and i have noticed ice on the back wall of the freezer compartment


Your cooling coils have frosted so much that there is ice forming allover the cooling coils and preventing the actual cooling inthe fridge. First of all shut off the fridge for about 10 hours and wait for all the ice to defrost. Clean up your fridge well and then check inside of the freezer compartment for break in wiring, failure of the heater or the thermostat. Now put the fridge on and see if the cooling comes back.If the set works ok then dont worry till you experience the same fault coming back. In this case your auto defrost timer could be faulty as it is not doing the 8 hours cycle defrosting. Check this out test and replace . Get help if you are not familiar. good day
