Refrigerator fridgidare control board replacement

Please make sure to click on General above and select the correct appliance type first.

Brand: Frigidaire
Model Number: FPHC2398 LF3
Main Symptom: no light in fresh side
What happens & when:

The refrigerator is a 14-year-old Frigidaire. The light does not turn on in the fresh food compartment, while the freezer light does turn on. The door switch is OK. I checked it: the switch is good and power is present at the switch. The bulbs are also OK. The bulbs are not LED type.
I ordered a control board (part number listed above). I selected a compatible board using the parts lookup on an appliance parts website. After installing the new board, neither the compressor nor the refrigerator starts, and the freezer light also does not turn on. At the same time, when the original board is installed, the light turns on and the refrigerator works normally, except for the fresh food light.
What could be the issue? Is this the wrong part, or is the replacement part defective?

Thank you.

Hello, according to the model number that is the correct part. There are some situations with certain models where the front interface has to be changed out as well. You may try replacing it under warranty before resorting to changing out the front interface.

Is it possible that this board should be programmed or something else..

There are no jumpers or programming on these boards. I have put a bunch on through the years. I have seen a lot of issues where the communication between the interface and the board underneath would not work. I know for a fact that there are some boards that actually came with the front interface along with the main board. You might reach out to Frigadaire to see if there are any service bulletins on your model.
