Wiring diagram for whirlpool model et20dkxzn00


Check their technical website for diagram. 105 volts is a little low, but the timer should operate. I would suspect the timer or one of the components in the defrost system like the defrost heater, defrost safety thermostat.

I can't find the wiring diagram for my whirlpool refridgerator.... MOD.#ET19RKXFN01 SER.#EG3222178. Can you please help. I need to change the defrost timer.....Thanks


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

How to set the defrost duration on a timer


Copy following link for defrost timers:
http://waterheatertimer.org/Paragon-timers-and-manuals.html#defrost

There are 2 general types defrost timers.
Time activated - Time terminated
Time activated - Temperature-pressure terminated, with timed termination back-up

Here is basic image:
http://waterheatertimer.org/images/8145-work-image.jpg
Rotate dial until current time lines up with pointer, insert tripper pin on outside edge of dial to select defrost start-time, move defrost duration tripper on inner dial to set termination time.

Each defrost timer is slightly different:
If timer is time-terminated, then wiring follows certain diagram.
If timer is temperature-pressure terminated, then different wiring diagram is used.

I need a three phase wiring diagram for 8145-20 model timer.


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

I have a paragon 8145-20 defrost timer. do you wire the compressor to the timer? I cant seem to find a wiring diagram on how to wire this correctly


Link below has wiring diagrams and wiring manuals for 240V 8145-20
http://waterheatertimer.org/Paragon-timers-and-manuals.html#defrost

I am not expert installing defrost timers.
According to information from Paragon, 8145 is for hot gas defrosting. 8140 series are time initiated, and pressure-or-temperature terminated.
Wiring diagram does not show compressor wired to timer.

The cycle works like this:
Timer is running but defrost is not switched ON.
Fan is ON.
Timer switches ON and activates defrost cycle.
Fan turns OFF. Hot gas valve turns ON for defrosting.
Cycle limit switch is temperature or pressure sensitive.
Cycle limit switch reaches trip point, timer switches OFF.
Hot gas valve turns OFF. Fan turns ON.
So fan is off during defrost cycle.
Hot gas valve turns ON when timer switches ON.
Timer is switched OFF by pressure-or-temperature limit switch.

I have installed 3 paragon timers and this is the first to give me trouble. When the defrost cycle started it did cut off but the timer was stuck on defrost. Many techs have done strange things to the...


You need someone to come in and trace the wiring if you cannot figure it out. You said you had the Paragon wiring diagram already, if not the link below can be used.

This defrost time can be used for both hot gas and electric heater defrosting so check to see which defrost type is being used.
