Jenn-Air JF36NXFXDE00 fridge service bulletins and tech manual request

[Ananda]

Manufacturer: Whirlpool

Type of Appliance: Refrigerator

Model Number: JF36NXFXDE00

Have you validated the model number at an online parts site like Repair Clinic? (yes or no): Yes

Have you watched the video on how to search for manuals and have you searched the Downloads section prior to posting this request? (yes or no): Yes

Does anyone have access to these technical documents: tech sheet, service manual, and service bulletins related to no power, no cooling, dead console, no fans, no operation, etc. I'm not talking about the single point led lighting issue.

@Ananda This is in a troubleshooting section on there site: 

Power Outage (“PO”) Code

Possible Solutions

NOTE: When a power outage occurs, a Power Outage indicator light will be displayed. Press any Home Screen touch pad (Fridge, Freezer or Options) to turn off the indicator light. The power outage indicator light will not display when either Cooling Off or Sabbath mode is active, but will appear after exiting Sabbath mode if a power outage occurred.

Check For Faulty Outlet

Check for 120 VAC at the outlet. Verify that the outlet has the proper polarity and is grounded.

 

“PO” Comes Back After 30 Minutes

1. The control panel temperature display will read “PO” and an alert tone will sound three times.
2. “Confirm” will blink until you acknowledge the power outage by pressing the measured fill button.
3. Once the power outage has been confirmed (by pressing the measured fill button), the “PO” will turn off, and the display will return to the home screen.
4. If the PO comes back,look for a part shorting out. Refer to “Check for the Shorted Components” section.

Loose Wire Harness

Check for loose connections or backed-out wiring from the connector. Resecure any loose connections.

Missing Voltage at the Power Supply Board

Check for 120 VAC at the Power supply board. J1-1 BK to J1-2 WH = 120 VAC.

 

1. If voltage is not present, check the wiring harness and connection.
2. If AC voltage is present, then check J2-1 BK to J2-5 GY = 14 VDC.

3. If DC voltage is not present at the Power supply board, then go to shorted component sections.

4. If DC voltage is present now, check for wiring issues or Temperature UI board issues.

Shorted Components

If any of the low voltage components short out, it will cause the unit to shut down.

1. Unplug the unit from the wall.
2. Then unplug the RC and FC fans at HV board P14 and P13.
3. Plug the unit back in and see if the dispenser temperature UI comes on.
4. If the temperature UI comes on, check the RC or FC fans or wiring for issues.
5. If the temperature UI display still does not come on, go to the Faulty temperature UI section.

Thank you!

@Ananda Also this:

No Operation

Possible Solution

No Power to the Appliance

Check the circuit breaker and outlet for proper voltage, polarity, and grounding.

 

Loose Wire Harness

Check for loose connections or backed-out wiring from the connector. Secure any loose connections.

No Voltage to Main ON/OFF Switch

Check power to the Main power switch between the BLK and White for 120 VAC

1. If the voltage is present, then go to check power at the Vultan power supply.
2. If no voltage is present, then check the cord and outlet.

Missing voltage at the Power Supply Board

Check for 120 VAC at the Power supply board. J1-1 BK to J1-2 WH = 120 VAC.

1. If voltage is not present, check the wiring harness and connection.
2. If AC voltage is present, then check J2-1 BK to J2-5 GY = 14 VDC.
3. If DC voltage is not present at the Power supply board, then go to shorted component sections.
4. If DC voltage is present now, check for wiring issues or Temperature UI board issues.

Check for Shorted Components

If any of the low voltage components short out, it will cause the unit to shut down.

1. Unplug the unit from the wall.
2. Then unplug the RC and FC fans at HV board P14 and P13.
3. Plug the unit back in and see if the dispenser Temp UI comes on.
4. If the Temp UI comes on, check the RC or FC fans or wiring for issues.
5. If the Temp UI display still does not come on, go to the Faulty Temp UI section.

Faulty Temp UI Communication Line

1. Check for any loose wiring connections.
2. Run the service mode on the unit to see if any component works.
3. If no component works, but the Stealth dispenser board will go through test modes, check the communication line from the Temp UI board to HV board. Ohm out from temp UI board J8-3 GN to HV board P4-3 GN.

     

  

 

4. If the communication line is open, check the wiring connections at the Temp UI board to the HV board.

5. If the communication line is good, change the HV board.

In this case, it was A bent electrical outlet plug that supplies power to the refrigerator. I measured 71 volts coming into the fridge from the wire harness, but 123 volts at a good outlet. I straightened the prongs and it brought 117 volts to the fridge.
