Where is defrost timer on amana arrccb - Amana ARB224RCC Bottom Freezer Refrigerator

check to see if defrost fan working

See other post.

the defrost timer has stopped working.
it should have timed out and started cooling again
You may need a new defroat timer
A technician can help you with that

Defrost cycling problem which will affect cooling the fridge compartment by struck the freezer fan's function.To solve defrost problem:
First, locate the defrost timer which may hidden behindcorners of the fridge at the back bottom, in some models located in the ceilingof the fresh food section or behind the cold control cover. Once you locate thedefrost timer, slowly turn the screw in the middle of the defrost timer withstraight screwdriver until the fridge shuts off. Now it's in defrost. If thedefrost heater(s) starts, replace the defrost timer and defrost thermostat. Ifthe heater(s) does not start, unplug wire cord to check ohm test for continuityof heater. If continuity is there, plug cord wire which gives power 120volts(check specification) to heater. If heater no starts, bypass defrost thermostatby join the 2 wires in the defrost thermostat. If the heater now comes on,replace the defrost timer and defrost thermostat. If the heater itself is bad,replace it. Thanks and hope helpful.

Relax, some people exagerate was all I was saying.
Anyhow, go to a good parts store and ask for a Supco EDT (Electronic Defrost Timer) replacement as they are more reliable and not much difference in price.

rotate defrost timer till compressor off
does it defrost if no then
jump out defrost t-stat (round disc)
if starts to defrost Replace defrost t-stat
if yes replace defrost timer if not turning

you might have a defrost problem. Frost free models have a heating element that is controlled by a timer to automatically defrost ice, ie 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

Amana adaptive defrost:

Press refrigerator light switch five times in six seconds to initiate defrost cycle. Pressing five more times within six seconds will cancel defrost and go straight into the run mode. Similar operation on both bottom mount and SxS refrigerators. After the defrost terminator/thermostat opens, six minutes of dwell time occurs before the compressor and condenser fan motor will operate. After defrost terminator/thermostat open, 10 minutes of dwell time occurs before the evaporator fan motor will operate.

could be thermostat or defrost heater or defrost timer.you can check the heater with meters that check continuity.the thermostatis located on top coil and sometimes they will seperate.so look for those 2 things.most likely it will be one of the 2.the defrost timer is most likely good,if you hear your machine turn off and back on then the timer is good.

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