FGHF2344MF6 Frigidaire Fridge either too warm or too cold

I have a FGHF2344MF6 Refrigerator side by side, and I was wondering if you could help steer me in the right direction.

The fridge after a while, goes from its set temperature up to a warmer temperature overnight occasionally (ie. From 2 degrees to 8 degrees), in doing this I reset the fridge and bought a new temperature sensor (part number – PS1765215) and replaced the old one with the new one. This caused the fridge to become too cold, As in, no matter the temperature I would set it at, the fridge would sit around 0 degrees and freeze the items inside the fridge. So i re-installed the old temperature sensor and it is back doing the opposite of freezing the fridge, and now does not keep the fridge cold.

Any ideas would be great
PS1765215=Manufacturer Part Number 240597203

0 degrees C? Which would be 32 degrees F.

Its best to manually ohm test the Fresh Food Temperature sensor with a multimeter. You could have received a defective thermistor, which can happen at times.

Place the Fresh Food Temperature sensor is a small glass and fill it with crushed ice. Add enough water to cover the Fresh Food Temperature sensor. Then wait at least 5 minutes. This should bring the temperature of the Fresh Food Temperature sensor very close to 32*F-33*F. At 33*F the Fresh Food Temperature sensor should measure 31,658 ohms. At 32*F the Fresh Food Temperature sensor should measure 32,566 ohms (+ or - 2%). Your Fresh Food Temperature sensor should be between 31.6K and 32.5K ohms.

Here's the Fresh Food Temperature sensor for your model you can order, if yours ohm tests bad:

Here's the video to access/replace both of them:

If the Fresh Food Temperature sensor ohm tests good, then check your main control board to see if you notice any burnt spots on it. Disconnect power to the refrigerator first.

Here's the main control board for your model, if needed:

These videos gives you the general idea of how to access it:

Thank you for the reply,

I have ended up buying another sensor for now, I’m starting to lean towards the the board is also an issue as it seems my defrost doesn’t work as well as intended, but I just replaced all my relays as they were broken the one in the fridge behind the ice maker and the freezer.
