Could be the main control board , or the #4 thermistor . Replace the thermistor first . This white piece , about 1 " long , is clipped to the top left , on the evaporator coils . 2 white wires go to it .

Entire cooling shut down - restarted 10 hours later, shut down again 12 hours after restarting.

Hi and welcome to FixYa, I am Kelly.

The defrost cycle is usually terminated by a 60 Deg bi-metal thermostat. If the defrost heating element is not heating up the unit will shut off until the internal temp reached 60 Deg F and then restart.

Defrost cycles are 10 - 12 hours apart depending on the defrost control installed so that explains the 12 hr repeat. I really think you have a bad defrost heating element. Here is why I say that...
1. The Defrost cycle is 12 hours after last defrost. (Means the defrost control /board is working)
2. The defrost cycle terminates at 60 Deg F
3. No working defrost element will cause very very long defrost cycles due to the time it takes for the compartment to warm up to 60 deg F and terminate the defrost cycle.

The element is item 33 of this link:

Just looking at the drawing it appears that the Defrost heater and defrost thermostat are an assembly.

You should be able to read resistance end to end on the heater assembly. If you have no resistance it is most likely open / has failed.

The defrost thermostat will read resistance anytime compartment temp is BELOW 60 deg F.

Thanks for choosing FixYa.

Freezer is not auto defrosting., I am manually defrosting every couple of weeks, what could be the problem? Pat G .Pencil Bluff,AR

There is a defrost timer, defrost thermostat, and the heating element. The element is in the rear of the freezer behind the rear panel. You can use an ohmmeter to test the continuity of the heating element, the timer, and the thermostat. One of them is faulty.

Top half of both fridge and freezer appears to have stopped working.

Your defrost heater or defrost thermostat may be bad. Test defrost heating element for continuity. If heater is good, replace the defrost thermostat. In most cases, replacing both is advisable.

My Maytag side-by-side is a MSD2655HEQ. The coils in the freezer compartment keep frosting over and the refrigerator side quits keeping cool air. I've defrosted the coils with a blow dryer and the...

The defrost circuit in you freezer has failed that is why you have to defrost the coils. The defrost circuit consists of the heater element, the defrost thermostat and the control module. The control module turns off the compressor and powers up the heating element to melt the ice on the coil, after the coil reaches 40 deg F the thermostat cuts off power to the heater. The heating element and thermostat is mounted to the coil. If you have a multimeter and know how to use one, you can check the thermostat and heater. You can check the heating element with a multimeter to see if it has electrically opened. If it has then you will need to replace it. Check also the thermostat, it should be in series with the heater. It should read close to 0 ohms if it is freezing and read infinite ohms if the temperature is above 40F. If the thermostat and heater check out, the problem might be with the control module.

I have an older GE Profile side by side not defrosting, have continuity in element when warmed thermostat kicks off and I have replaced the timer, still not defrosting. Model #THP21PBSMWW S/N SL238841

Need to check and see if the element is heating up when it goes into defrost. If the thermostat is bad it will not go into defrost. I purchased a new heating element for my GE and it came with the element and thermostat together. Also make sure the fan is running in the freezer this moves the heat through the coil as well as the cold temp when in freeze mode.

Okay, rookie ;)
Amana fridges have problem with the defrost thermostat, which you may not notice without looking at the thermostat very closely. If the plastic cover on the thermostat is swollen or is higher on one side - replace the thermostat. Fan in these fridges is connected in series with the heater and the defrost thermostat.
... And finally 127 Ohms for a 110v heating element is too high, resistance must be lower. If you measure it through the defrost thermostat - separate them and check again.

The refrigerator side has stopped cooling.

, 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

Defrost heater not turninh on

That model has what is called a adaptive defrost on it this fails very often it is located inside the ref under the control panel, The only other possible cause would be a defrost thermostat, this is located near the heater.

Samsung fridge rs52530bwp the fridge side will not work

I have a similar situation before in your case if your heating element is working then you are lucky I had a samsung fridge and the defrost heating element was bad and i was forced to install a different one because i would have to change the hole evaporator in order to replace the heating element so what dit was to use a mechanical 10 hour defrost timer and install a generic heating element and a defrost thermostat on serial so it want work on less the evaporator has froze over i drill a hole to the back of the fridge and i wren the cables to the back of the fridge cover then whit foil tape an take power directly from the power cord i install the timer next to the control board so every 10 hours will give power to the heating element but will not come on unless the evaporator has froze up. on my case i had to do it like that because the heating element i use was to strong for the control board and would just burn it up. but will work even better using the original heating element. NOTE: find the diagram of a old fridge that will help you to figure out how to install the timer and the defrost thermostat no need for the timer to cut off the compressor keep in mind than the defrost thermostat only close the circuit when is chill below freezing so i recommend to use a new one I hope this help you
