Question about Amana ABB1927DE Bottom Freezer Refrigerator

Refridgerator not cool enough.

Freezer is icing up so much that air flow not reaching refridgerator. Could this be our defrost timer or defrost heater? How can we determine which one it is? When we manually defrost, refridgerater works for about two weeks, then problem reoccurs.

Our Kenmore bottom freezer (made by Amana) did the same thing -- technician replaced both the defrost timer and and the defrost thermostat -- that seems to have fixed problem.

Sounds like the probable cause is defrost heater. get someone to test the element.

My Amana refridgerator does not cool but the freezer works

If you have noticed a rise in temperature in the fridge, and there seems to be fromst building up in the freezer than your problem is one or more parts of the defrost system is malfunctioned and in return your problem arises. There are three parts to the system, the defrost timer or in some cases control board, defrost thermostat also known as a bi-metal, and the defrost heater. The defrost system is set up to operate as so. The defrost timer or control board will turn the machine off, in some cases every 8 hours, some 12. During this time period the defrost heaters, located behind the freezer wall and rest underneath the evaporator, yet wires to them run up the side of it, are energized and emit heat that raises upward to melt the ice that has formed on the evaporator coils. The bi-metal or defrost thermostat is at the top of the evaporator. When the heat from the heater starts to reach the bi-metal, it breaks the circuit turning the heater off. The whole purpose of this is because the freezer cool the refridgerator side by drawing air across the coils and blowing to the other side via the evap fan motor. In my opinion, if you change one part of the defrost system change them all because usually when one part fails another will follow, so save yourself the time and the food loss, the cost difference is minute.

Refirdgerator won't cool proprely on refridgerator side

Hi SN,

This could be a couple of things, but you should check for evaporator icing, even though you said the freezer is working and the defrost control appears to be ok. If the evaporator is iced up, no air willl flow into the fridge section even if the fan is running.

You can also check the damper control board. I am sending you a link that shows a complete breakdown of your appliance. I do not work for this company nor am I affiliated with them in any way. They also have a troubleshooting section and contact information. See:

The refridgerator is not staying cold. The

DEFROST PROBLEM
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad, it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others. You can post your model number into one of several appliance parts sites on the internet and search for defrost components to find your parts.

Freezer side of refridgerator doesn't freeze foods properly and also makes only about 10 cubes a day. food side works fine, it's a Hotpoint model #HSS251FMB WW

If freezer is icing up, you might have a defrost problem. Frost free models have a heating element that is controlled by a timer to automatically defrost ice, defrost timer turns on defrost heating element every 12 hours to melt ice in freezer and allow good air flow.
You can test defrost element with an ohm meter(located inside freezer coils-will have two wires going to a plug connection), if OK replace defrost timer (located in various places depending on make and model

Refrigerator side not cooling

The fresh food section is cooled by the freezer section by forced air supplied by a fan. If you have air flow, check the temp inside the freezer. It should be between 0 and -10. If not look inside your freezer and see if you have ice built up on the back panel. If so you have a defrost problem that is most likely a bad defrost heater, a bad termination thermostat or timer. If ther is no ice then check your fan under the refrig. If you can hear the compressor running it should be turning. If this all checks out then you have a freon system problem like. Low Freon pressure or a restriction.
