Samsung Refrigerator Temp Display Flashing? Back Wall Frozen Over – Chandler, AZ Repair

Posted by August 12th, 2025

When your Samsung refrigerator starts flashing its temperature display and the fridge compartment feels warmer than normal — but the freezer is still fine — it’s a sign of a cooling airflow issue. That’s exactly what happened for a Chandler homeowner who found Phoenix Appliance Repair on Google.

The Problem: Flashing Temp Display & Warmer Fridge Section

The customer noticed their fridge’s digital temp reading flashing on and off for over a day. Food in the refrigerator section felt slightly warmer than usual, but the freezer was still keeping items frozen.

Our diagnostic process revealed the cause: the fridge’s back wall was completely frozen over. When ice builds up on the evaporator cover, it blocks airflow between the freezer and fridge sections — meaning your freezer works fine, but the refrigerator can’t get enough cold air.

The Next Step: Defrost Before Repair

To safely complete the repair, the unit needs to be fully defrosted for 24 hours. This allows us to access the evaporator area without damaging components and ensures any blocked air passages are cleared.

Potential Parts Needed for the Repair

We’ll arrive prepared with the most common parts required for this issue, so we can complete the fix in one visit:

• DA47-00244Q – Heating Element (prevents frost build-up)
• DA32-10104N – Temperature Sensor (monitors cooling performance)
• DA47-00301D – Bimetal Thermostat (protects against overheating)
• DA97-12609C – Evaporator Cover Assembly (restores proper airflow)

Why This Happens on Samsung Refrigerators

Many Samsung French door and side-by-side refrigerators are prone to ice build-up behind the evaporator cover due to defrost system failures. If the heating element, sensor, or thermostat isn’t working properly, frost accumulates over time, eventually blocking airflow and triggering temperature errors.
