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.

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.

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.

Mullion heater connection for Amana 84" Integrated bottom mount refer model B136CAR3 mfg P1318402W. I need to hook up the mullion heater that is under the freezer, component P/N 12401301. But I cannot find the mullion heater connection point. According to the specs it's installed in the foam and not wired from the factory and is for service purposes. The reason for this is that the water from the defrost cycle re-freezes and clogs the drain hole. Eventually the ice gets almost an inch thick and it's SOLID. The freezer drawer cannot open, so I have to thaw it all out and pry it open. I've done this dozens of times over the years! The service tech never figured it out. But with help of my boat-refer-expert brother we found the solution at the high level. Devil is in the details. According to the instructions: make a slit and peel back the white vinyl harness sleeve that goes to the water valve, pull out two wires (black and white) that aren't connected to anything (yet). Then "locate the mullion heater leads at the left side of the cabinet and connect to the back and white leads". Then Wrap vinyl sleeve with electrical tape to seal the slit. OOOOOKAY.... I found the unconnected leads in the harness that goes to the ice maker water valve. They have male bullet style plugs and clips (a little corroded) but I cannot find anywhere to connect them... Is left side of the cabinet as viewed from the front or back? The main harness is on the left rear area. And if I make the slit long enough (which is very difficult, then the wires could make it back there. If I only could find where the mullion heater's connectors come out. Of course the wiring diagram only shows the mullion wiring as optional and not connected to anything. I really do not want to lay this 500lb (at least) beast on it's side. It already fell on me and my daughter, but a countertop and pallets save us. This refer has been nothing but a pain to deal with ever since I bought in 2001. I don't want to get rid of it, since it has custom wood panels that go with our kitchen, and I fell on hard times (due to illness) and cannot afford a new one. It fixed many things on it already. Such as the problem where the relays weren't soldered properly onto the main logic board, which fixed the non-defrosting problem and the freezer fan not working. But now the drain hole plugs with ice. So I read that many freezers have a 5W to 20W heater that runs all the time to keep the hole from freezing. Especially if water gets in the insulation under the floor of the freezer. Anyway, can anyone tell me how to find the connections to the mullion heater? Is it in the outside-rear channel up back of the refer? it's pop-riveted on. Thanks! Scott
