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

Unsure what you are trying to do.

If you want to by-pass defrost cycle, remove trippers from dial and timer will not enter defrost state.
Or remove wire that is connected to terminal 3.

Defrost problem. Check, defrost timer, thermostat, heater are working properly.
First, locate the defrost timer which may hiddenbehind corners of the fridge at the back bottom, in some models located in theceiling of the fresh food section or behind the cold control cover. Once youlocate the defrost timer, slowly turn the screw in the middle of the defrosttimer with straight screwdriver until the fridge shuts off. Now it's indefrost. If the defrost heater(s) starts, replace the defrost timer and defrostthermostat. If the heater(s) does not start, unplug wire cord to check ohm testfor continuity of heater. If continuity is there, plug cord wire which givespower 120volts (check specification) to heater. If heater no starts, bypassdefrost thermostat by join the 2 wires in the defrost thermostat. If the heaternow comes on, replace the defrost timer and defrost thermostat. If the heateritself is bad, replace it. Thanks and hope helpful

8145-20 240Volt Paragon timer is not 3-phase.
Clock motor is 240V.
You need a transformer to convert 3-phase to single phase 240V to operate timer.
Then timer outputs can control 3-phase power using 3-phase contactors
Contactor below is 3 phase with 240V coil

Repair the defrost system, defrost timer,defrost thermostat and defrost heater.

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
