Frigidaire Refrigerator temperature not stable | Fix Guide
Measure the refrigerator and freezer temperatures, confirm the settings, then allow up to 24 hours after installation, a power interruption, or an adjustment for temperatures to stabilize. Frigidaire's family guidance uses 37°F for the refrigerator and 0°F for the freezer as suggested settings, says blocked vents or a door that does not seal can cause unstable temperature, and says a warm room or restricted rear airflow can make the compressor work harder.
