I have a question or a problem, I changed the damper

Customer Question

Good evening, I have a question or a problem, I changed the damper control, I changed the refrigerator temperature sensor and I changed the electronic control board, but it is still flashing the number 4, the freezer temperature sensor is working because the freezer fan is running. Do you have any ideal what could continue to cause that problem.
JA: What's the make and model of the fridge? And can you guesstimate how old is it?
Customer: It is a Fridigaire and the model number is ***** and it about 8 years old.
JA: Do you plan on doing the work yourself?
Customer: Yes
JA: Anything else we should know to help you best?
Customer: No that's about it.

Please allow me just a few minutes to prepare some information for you, thank you!

Customer: replied 2 months ago.
Okay.
Expert:  Kelly replied 2 months ago.

The flashing 4 means the control cannot "see" what the damper is doing. You replaced the damper itself and the main control?

Customer: replied 2 months ago.
I have replaced both.
Expert:  Kelly replied 2 months ago.

Number 23 and 115 in the picture at the link below were replaced?

Okay, it would be very unlikely that one of those parts would still be faulty, so I suspect it lies with the wiring between the control and the damper.

Customer: replied 2 months ago.
A wire could be broken or what?
Expert:  Kelly replied 2 months ago.

I haveno doubt you made sure the connections were tight, so it is likely something more dramatic, like a pinched wire that is open in the insulation or a connector issue.

Expert:  Kelly replied 2 months ago.

Sometimes the wire breaks right at the connector but the insulation is intact. Do you have a meter to perform any resistance checking between the control and damper?

Customer: replied 2 months ago.
Okay, I check all the connectors and wires.
Expert:  Kelly replied 2 months ago.

I will get you a wiring diagram to help. Please allow me just a few minutes to prepare some information for you, thank you!

Customer: replied 2 months ago.
I do, and I will check the damper back to the controller.
Expert:  Kelly replied 2 months ago.

J1-2 is the damper voltage from the control, J1-11 is the switch on the damper to the control. The issue is likely to be in that J1-11 connector/wire.

Expert:  Kelly replied 2 months ago.

The wiring diagram is attached.

Customer: replied 2 months ago.
Okay
Expert:  Kelly replied 2 months ago.

Let me know what you find, thank you!

Expert:  Kelly replied 2 months ago.

J1-11 and J1-12 on the control are the damper switch wires.

Customer: replied 2 months ago.
I will definitely let you know what I find out, and thank you.

Thank you!
