Brand: Frigidaire Model Number:GRMS2773AF01 Main Symptom: HI Error Code What happens & when: My Frigidaire Gallery shows HI temp at 55°F. The upper refrigerator shelf is semi cold (the twintech air filter area), the lower shelf (crisp seal fresh area) is colder, and the freezer works.
Error Code (if any): HI error code
Parts or tests already tried: Clearing the HI temp code alert, but it keeps appearing and beeping again after a couple of hours, then I checked the air filters and seals. We’ve only had this fridge for a year and a half so of course nothing was wrong with those. I also tried to unplug and remove everything from the fridge and let it sit with all doors open for 24 hours. The last thing I tried was replacing the fan motor.

Thanks for all the details! Since your Frigidaire Gallery GRMS2773AF01 is showing a HI temperature warning around 55°F, but the freezer is still working, I’d concentrate on what’s preventing the refrigerator section from cooling properly.
The HI warning means the refrigerator temperature is too high. Clearing the alert only silences it temporarily. If the temperature stays above the normal range, the warning will return.
You’ve already done quite a bit of troubleshooting, including a full 24-hour defrost and replacing the fan motor. I wouldn’t recommend replacing any more parts until we narrow down the problem.
Here’s what I’d check next
1. Check the refrigerator evaporator for frost. Your refrigerator uses Frigidaire’s TwinTech cooling system, which has separate evaporators for the refrigerator and freezer. That means the freezer can work normally even when the refrigerator has a cooling problem.
2. Check whether the new fan is actually running. A new fan motor doesn’t necessarily mean it’s receiving power or being commanded to run. With the refrigerator operating and the door switches closed, listen for the fan and check for airflow. Keep in mind that the fan may shut off during defrost or when the doors are open.
3. Inspect the refrigerator evaporator frost pattern. If the evaporator has a light, even frost pattern while actively cooling, that’s generally a good sign. If it’s completely packed with ice, we may have a defrost problem. If only a small section develops frost after sufficient running time, that could indicate a sealed-system problem.
4. Check the refrigerator temperature sensor. A faulty thermistor or wiring connection could cause the control board to receive incorrect temperature information and affect cooling operation.
Since you’ve already allowed the refrigerator to defrost for 24 hours, an ice blockage is less likely if the refrigerator never cooled properly afterward. However, if it cooled normally for a day or two before warming up again, that would make a defrost or airflow problem more likely.
A few questions that will help narrow this down
After leaving the refrigerator unplugged for 24 hours, did it ever return to around 37°F, or did it remain near 55°F?
Which fan motor did you replace: the fan inside the refrigerator compartment, the freezer fan, or the fan near the compressor?
What is the actual freezer temperature? Is it holding around 0°F?
When the refrigerator is running, can you hear the fan operating inside the fresh-food compartment?
The answers will help us determine whether we’re dealing with an airflow issue, a defrost problem, a temperature sensor, or the refrigerator’s cooling system.
One important note: Since this refrigerator is only about 18 months old, check your Frigidaire warranty documentation before paying for sealed-system repairs. This model uses R-600a refrigerant, so refrigerant-system work should be handled by a qualified technician.

Also, if the refrigerator is actually holding at 55°F, move perishable food to another refrigerator until the problem is corrected.
Thanks for the photo and the additional information! This helps narrow things down quite a bit.
I can confirm that the fan in your picture is an Electrolux motor fan, part number 5304536608. However, I can’t confirm from the part number alone whether the technician installed it in the refrigerator or freezer compartment.
Since your Frigidaire GRMS2773AF01 freezer is maintaining around 0°F, but the refrigerator remains near 55°F even after a full 24-hour defrost, I’m leaning toward an air circulation problem in the refrigerator compartment, rather than a compressor or sealed-system issue.
The fact that the refrigerator didn’t cool down after being unplugged for 24 hours also makes a simple frost blockage less likely, although we haven’t completely ruled it out.
Here’s what I’d like you to check next.
Check the refrigerator fan. Open the refrigerator doors and listen for the fan. Some fans shut off when the door opens, so you may need to press and hold the door switch to get it running. If you hear a fan, try to determine whether the sound is coming from the refrigerator or freezer compartment.
Check for airflow. With the refrigerator running and the door switches activated, place your hand near the air outlets inside the refrigerator. Do you feel any cold air moving? Little or no airflow could point toward a fan, airflow passage, or control issue.
Check the temperature at different levels. Since you previously mentioned that the lower refrigerator section feels colder than the upper shelves, I’d like to know whether the bottom is actually reaching normal refrigerator temperatures, around 37–40°F, while the upper section remains near 55°F. That difference would be an important clue.
At this point, I wouldn’t recommend replacing another fan or control board until we verify which fan was replaced and whether the refrigerator is receiving proper airflow.
One question: When you open the refrigerator, does the upper section feel noticeably warmer than the lower drawers, or does the entire refrigerator seem to be around 55°F?
That will help us determine whether we’re dealing with an airflow distribution problem or a more general cooling issue.
Also, since 55°F is above the safe food-storage temperature, I’d recommend moving perishable foods to another refrigerator until we get this resolved.
