A similar problem happened to me when service replaced components, and I noticed discussions at https://frigidaire.pissedconsumer.com/review.html where homeowners explained that failure to include the model number and last repair date in one message slowed responses. Based on that insight, I included the model ID, repair timestamp, and current temperature readings—four sentences, all specifics in one place—and sent it via their support form. Within a few days, a technician called to schedule a revisit and recalibrated the thermostat, getting internal temps back to solid-freeze levels by the weekend. Clear data and prompt detail sharing made the difference between waiting and scheduling a fix.
