My Frigidaire PHSC239DSB2 side by side's digital temperture display is flashing a 2 on the freezer side & the fresh food sides temperature went up to 47 degrees, but has no flash. What is goin

Hello Michael, I appreciate your inquiry!

Based off the information you have provided your Frigidaire refrigerator is dropping the temperature within the fresh food side. The damper is located within the back of the fresh food side and this part will open and close so that the cold air from the freezer will come into the fresh food side. It is possible that this damper can be stuck open or staying open for too long. Do you notice any frost developing within the freezer? If so, please perform a manual defrost on the refrigerator and you can do that by disconnecting power from it for at least one hour. If there is no frost within the freezer then check to make sure no packages are holding the damper open. You may need to replace the damper or the damper motor and I would recommend having a professional technician out to perform proper replacement repairs. Best of luck! -Matt

Typical settings for a refrigerator / freezer:
Fresh food compartment is around 35 - 36 degrees F,
Freezer compartment is anywhere between -10 and 0 degrees F.

adjust the temp on the freezer setting where it links up with the frig'...

Hello - Could it possibly be HI? Typically error code HI indicates that the unit has detected high temperature in freezer. Try setting the unit to a lower setting. Generally the factory setting is 0 for the freezer temperature and 37 for the fresh food temperature.

From what I remember a flashing 4 means "damper error". Send your model number found inside or on the outside of the fresh food section, The air damper is found between the freezer and fresh food section and regulates temperature in the fresh food section by opening wide for things that warm up your fresh food section example would be opening the door and letting warm air inside . The damper then closes to keep the right temperature. If you have questions please ask, Thanks Sea Breeze

Hello Bryce,
I found a manual, although I cannot be sure it is for your exact model, it is located HERE. This is what is stated under "Temperature Adjustment"
IF TEMPERATURE DISPLAYS FLASH... If ever you see both temperature displays continously flashing, it may indicate that the control system has detected a performance problem. Call your service representative, who can interpret the flashing message. To maintain temperatures, a fan circulates air in the refrigerator and freezer compartments. For good circulation, do not block cold air vents with food items.
This is located under "Turning the Cooling System On and Off"
TURNING THE COOLING SYSTEM ON AND OFF You can disable the cooling system in your refrigerator by pressing the On/Off button located on the left side of the temperature control panel. To ensure that you do not accidentally turn off the cooling system, the button does not work unless you press and hold it for three seconds. Once you disable the cooling system, all refrigeration to the freezer and fresh food compartments stops. To turn the cooling system back on, you must again press and hold the On/Off button for three more seconds.
If the manual I selected is not the one for your particular machine, there are others located HERE. There are various ones only differing by a "upgrade" letter on the end, perhaps for different models of different manufacturers, produced by the same company.
I hope this is of some help

my Frigidaire showed the number 4 on the display after power outrage. And the temp is really warm inside. I unplug the power and plug it back 1 minute after. now I can set the temperature and it's working fine.

Auto Damper models, The Auto Damper model refrigerator has
two controls and both have capillary sensing.
The Auto Damper controls the fresh
food temperature and the Freezer Temperature
Control guides the freezer temperature.
The fresh food compartment temperature
is maintained by a damper assembly located
at the back of the temperature control
housing. Changes in air temperature
cause the damper door to open and close.
A control rod and gear connect the fresh
food control knob to the damper control.
Turning the fresh food control knob to the
COLDEST position increases the flow of
freezer air into the fresh food section. The
freezer compartment temperature control
warms at a faster rate and cools at a slower
rate, increasing the compressor run time
necessary to maintain a satisfied freezer
temperature control.
Turning the fresh food control knob to a
WARMER setting decreases the flow of
chilled air into the fresh food section. The
freezer compartment temperature control
warms at a slower rate and cools at a faster
rate, decreasing the compressor run time
necessary to maintain a satisfied freezer
temperature control.
It is ver possible that the auto damper has failed and will need to be cosidered as a likely cause.

Move the refrigerator to a room that is at least 50 degrees F.

Temps on most refrigerators are regulated by the fresh foods temp. If your garage is let's say 35 degrees, the fresh foods temp will most likely never raise enough to turn the refrigerator on. With the refrigerator never running, the freezer compartment will warm to 35 degrees, resulting in everything melting. Even if garage is a bit warmer, say 45, the refrig will not run long enough for the freezer to maintain a low enough temperture. If the garage temp falls to below freezing, say 20 degrees, the food in the fresh foods compartment will freeze. (outdoor beverage dispensers have internal heaters to prevent product from freezing !) Please don't rate this if not a Fix-Ya for you, as anything else lowers my score.

Same Guest as above posting this ... By the way, I have a FLSC238DS5 ... I spent 45 minutes on phone w/Frigidaire this afternoon (Phone#: 706-860-4110 Option 1 --> then Option 3). Didn't get anywhere. They say there are 3 solutions that should change it from C to F: 1) In between LED readouts for "Freezer Temp" and "Fresh Food Temp" there is a mode button that is hidden under the plate that you can press w/your finger OR 2) Hold "Fresh Food Temp" Up Arrow Key down, within 5 Seconds press "Freezer Temp" Up Arrow Key 3 times and it should change C to F or vice verse. Didn't work for me so she said 3rd option was to have a service tech come and diagnose. She said there would be a charge. I am not paying to have somebody come here to resolve this issue. That is when I asked her to escalate it to a supervisor which she did. Hopefully, I get a call back & a solution. Stay tuned ...
