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:

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:
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 trippers for parogon elect timer model # 4004-20

1) Paragon is no longer making timers or parts except defrost timers.
4004-20 240V 24-hour mechanical timer is not a defrost timer.

2) paragon 4000 series uses X2772 tripper.

3) Some sites still show the X2772 tripper.
Some sellers are seriously overcharging for the tripper.

4) If you want to buy new timer: Intermatic cross-reference guide shows T-104 240V 24 hour is correct replacement timer

5) Amazon sells new T104 for 50$ which is cheaper than some folks are selling the paragon tripper:

6) Change-over wiring from Paragon 4004-20 to T-104:
Hot wires from breakers. Paragon terminals 1 and 4. Intermatic terminals 1 and 3
Load wires. Paragon terminals 2 and 3. Intermatic terminals 2 and 4.

Mtb1953he fridge not cooling before it stopped fridge was making loud popping noise, i unplugged it then plugged it back in a day later to unthaw and fridge worked for 2 weeks now not working again. there...

It sounds like your defrost circuit is having a problem. Once frost builds up on the coil in the freezer compartment, air can no longer be pulled though the fins and circulated into the fresh food compartment. You notice things start to warm up. Eventually, the freezer suffers from the same lack of circulation and contents begin to soften and melt.

The defrost circuit consists of 4 main parts. They are: 1) defrost heater, 2) defrost terminator or sensor in series with the heater, 3) defrost timer and 4) wiring between the previous 3 parts.

The defrost heater is found in the compartment that houses the coiling coil. The defrost terminator or sensor is clipped or otherwise secured to be kept in physical contact with the cooling coil itself. The defrost timer may be located anywhere the manufacturer decides - a popular spot is in the toe space on the bottom of the fridge. The wiring, well, that is between all the parts. Chances are the wiring is fine - as would be the connectors to the individual components.

The defrost timer runs about 8 hours. About 20 - 30 minutes in that 8 hour period the defrost switch operates. This consists of switching power away from the compressor (so it shuts off) and to the defrost heater and defrost terminator. The heater is just a relatively small value heater that warms the compartment to melt any frost or ice from the cooling coil fins. It will be powered for up to 20 - 30 minutes by the timer or less - if the defrost terminator senses a rising temperature on the coil. This means that the heater will be on for either 20 - 30 minute OR until the defrost terminator gets warm enough.

If the timer is stuck - and never moves to the 20 - 30 defrost cycle, the frost on the coil will never melt away. If the timer does work, but the heating element has failed, the frost will never melt away. If the defrost terminator has failed open (preventing the power from getting to the heater), the will not work to melt the frost off the coil. If there is a loose, missing or damaged connection between the wiring harness and these components, it won't run as expected either.

Make sure there is continuity through the heater. When cold (below freezing) the terminator should also have continuity. Many are designed to open around 50 degrees F - so if you warm it up, you should see the continuity go away. The timer needs power to run, and will send power to either the compressor or defrost heater - never both at the same time. Check with power disconnected. Use care checking live circuits - and only work live circuits when you need to check for presence of power - otherwise, unplug!

I hope this helps. Please rate this reply - thanks!

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

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.

Why are there 6 hour 8 hour an 10 hour timers to defrost a self defrosting refrigerator

Good day,
The decision as what the time interval of a timer should be is determined by engineers and field tests.
There is more to the timer than interval. Timers are usually listed as 8 hours 21 minutes, 8 hours 30 minutes ect. The minutes is used to designate the time the control stays in defrost.
A general rule is if the interval is longer, the minutes in the defrost cycle is extended to compensate.
Other factors come into play such as the wattage of the defrost heaters and the defrost thermostat temperature.

The trend today, with timers is to extend the interval to make the machine more energy efficient.

There is never an issue to defrost more often then the original, but it will run the heaters more often, and cause increased operating cost and shortened heater life.
The short and long of it is you can use a 6 hour timer in any machine if the timer motor wiring is the same and the duration is long enough, but with the costs listed above.

Will not defrost . Is it a continuous run, 8 hour or 10 hour defrost?

Good day,
It's an 8 hour cumulative running time control. It runs when the compressor runs, and as well the defrost thermostat in the freezer compartment is closed. That's for the running mode, in the defrost mode it runs whether the defrost thermostat is open or closed, and as well whether the thermostat is on or off.
If it's a defrosting problem, it could well be the defrost thermostat, and in rare cases the main heater. They are both located behind the rear panel in the freezer compartment.
In order of frequency of failing,
1. Defrost thermostat
2. Timer
3. Main heater
4. Harness wiring plugs in the freezer compartment that connect these items.

I am not sure of your wiring but see no reason that you could not run straight from the breaker to the timer and the timer to the freezer. Determine how long you want the defrost time to be on each hour and set the pegs accordingly. This is if I understand or picture your timer correctly. You have a walk in Freezer, and a rather large box 110 volt timer,correct? The pins on the 24 hour timer wheel can be taken off or moved? If I am wrong, I am sorry. I have the wrong picture in mind.
