I will try to locate a wiring diagram for your model ET19RKXFN01 but to change the defrost timer you will only need to know its location. Here is a link to the repair parts=> ET19RKXFN01_Repair_Parts_List Go to page 5 of the repair parts list and you will see item number 4 Then on page 6 of the parts list you will see the timer part number beside the item 4. That is your defrost timer part number 2193084 Defrost Timer
Your refrigerator is an older model and may have the wiring digram in a packet behind the kick plate in the front near floor. Changing the defrost timer will not require use of a wiring diagram. Simply remove the old timer and replace the new defrost timer by plugging it into the wiring harness. The defrost timer can be found behind the control panel inside the fresh food compartment where the controls are located above the top shelf. If you have questions just let me know, Thanks Sea Breeze
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??
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.
Find defrost timer normally located behind the cover plate for the fresh food temperature thermostat. It will have a one way adjustable screw head on it. Turn the screw slowly until you hear a click (this would normally be where the defrost would begin) leave in this position for an hour or until you hear compressor kick back on. If you have water in catch pan of refrigerator you have bad timer. Otherwise you have bad heater or defrost thermostat. To check heater and thermostat I would go to parts site on Internet and type in model no. And see if they have diagnosis videos on this or similar ref. Otherwise buy the heaters and thermostat remove shelves, ice maker etc. To get to the liner of ref. Remove it and you can then remove and replace the heater and thermo. Be very careful as the cooling fins are sharp as razors.
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
Check for excessive frost build up in the freezer on the back panel. This would indicate that you have a defrost problem. One of 3 things cause a ref not to defrost. Defrost timer may not be advancing to the defrost position on the timer...The defrost thermostat, located on the evaporator in the freezer, measures open (bad)...or you have a bad defrost heater. If you have an electronic defrost control,which is used on most Maytag, Jenair, or Amana units, this could be your problem. If you turn the unit off for 24 hours to let it defrost manually then it will last for about 2 weeks before freeze up again.
