Question about Amana Refrigerators

1 Answer

I have an Amana bottom freezer refrigerator model BQ20RBL that builds up ice on the back wall of the freezer. There is no cold air entering the refrigerator upper box unless I also open the freezer door. The defrost timer (behind the front grill) does turn, and I have checked the contacts: OK. I have manually turned the defrost timer switch to 'defrost' but the frost does not go away. Two weeks ago, when this problem first occurred, I emptied the freezer and refrigerator, and let it thaw. Today the problem returned. What do you think is wrong?

Typically with this model it is either the timer or the defrost thermostat.

This is behind the back wall of the freezer. It is attached in series with the element. It is designed to open when the heater gets hot enough. The part is about the size of a stack of 6 quarters and typically has a blue end coating on one end. The other end is silver in colour and should be clipped on the black coloured heating element. It will have 2 wires coming out of the blue end.

If this part is defective then it will have to be replaced. by cutting a splicing a new one in. Be sure to unplug the fridge before replacing it.

There are 3 main components that can give issues; the timer, the thermostat and the heater. All 3 should be checked to confirm the fault. NOTE the timer contacts can be burned out as they arc under normal operation.

If you have a multimeter then you can check if the heater circuit has 0 or close to 0 resistance when there is frost on the back wall of the freezer. if it is then the timer is bad.

The ice buildup is the problem. Cold air must pass from the freezer to cool the refrigerator.
Link is to youtube videos about that problem.

My fridg and freezer is cold but not could enough the freezer wont keep food frozen. there is no ice build up, I replaced the defrost timer, and I cleaned the fan in the back what else could it be please...


Hello Nicole,

Their are a few things that couldbe causing your refrig.troubles.

1) their is ice build up in the return air vents that is not allowing air to flow correctly
you can see the air vents under the crispers in the ref.floor and can see if they
blocked with ice.

2) the freezer fan is bad and not circulating cold air into and out of the ref.

3) In addation to the defrost timer,perhaps the deforst heater and defrost thermostat are bad and frost is building up in the freezer,Do ya see frost
build up in the freezer??

Good morning: I used you trouble shooting web page. Went home and de-iced my fridge freezer. The bottom fan (at the bottom in the back) is working but the fan in the freezer is not going. Does this fan...


HI,
It is possible your fan motor in the freezer has failed and by not moving air into the upper chamber can cause frosting on the back wall of the freezer. Also lack of air movement can cause your air returns to seal shut with ice and still not work if your fan is replaced. The part number your will need is 63001057 for the fan motor itself. I would verify all air ports are open when you replace the fan motor. It not a difficult job, access would take a bit to get into the back wall of the freezer to replace the motor. Amana has been known to use fan delays to pre-chill evaporator before allowing the fan to run, if our model does this, the thermostat in the freezer would need to be checked also. When the thermostat closes, it sends power to the fan motor to run, if it fails, fan does not work. I would check this prior to ordering of replacing the fan.

either the evaporator coil behind the freezer compartment wall is iced over and you can';t move cold air over an iced up evaporator coil to cool the refrigerator compartment or the compressor relay/overload is bad

Fridge not getting cold enough


The cold from the freezer is piped up to the refrigerator and if that tube gets clogged with frost or ice it will not be able to blow to the cold air into the refrigerator area. I took everything out, unpluged the unit for about 6 hours, till all the frost from the freezer was gone, wiped up all moisture and turn it back on. It worked!

The freezer is cold but not cold enough to make ice


Check the back (interior) lower half of the freezer wall. If you see a frost build up, you either have an issue with your defrost cicuit (timer, heater, thermostat) or the evaporator (freezer) fan is not running. If there is not a frost build up on the back wall you either have a sealed system (weak compressor, leak or restriction) problem....or the condensor fan motor is not working. This would cause the compressor to overheat and shut down until cooled, and prevent the deep freeze.

Fridge not getting any air, freezer is working


I have a Kenmore w/ freezer on bottom. The top vent in the fridge is ducted to the freezer and is supposed to blow air. Mine was not.

I removed all the frozen goods and took off the back panel (inside to unit) which had a little ice on it. Underneath the panel was a solid wall of ice......including the motor which is supposed to blow air up to the 'fridge. I'd bet a beer that is your problem as well.

The ice seized motor will not be harmed because it is resistance loaded.

The best part is with a blow dryer and some elbow grease...the fix is free! I hope it helps.

Amana refrigerator warm


Chances are if they are getting cool but not cold-

1) the evaporator fan in the freezer is not running
2) Defrost heater has failed
3) Defrost sensor has failed
4) Defrost timer/refrigerator control has failed.

Check for ice build-up on the back wall of the freezer. If there is ice, unplug or turn the unit off for 6-8 hours with the doors open (put any food in a cooler with ice to maintain). Note water may come out of the refrigerator.
Plug the unit back in or turn it back on, close the doors, and check temperature after a couple of hours of operation. If all OK, you will need to have the above tested, or, if you know how to use a multimeter and can read a schematic/wiring diagram, I can instruct you on how to check the above.

Frig not cold but freezer is ice maker not making much ice either


Is your fan blowing in the freezer? Frost on the back wall of the freezer usually indicates a defrost problem... defrost themostate, heaters, take back panel off and check evap for frost build up and if your fan in working.
