Air movement changed when another door was open
An open door changes cabinet pressure. After the refrigerator was reassembled, the temperature still did not recover, so that observation could not justify a damper order.
If the freezer still freezes food while the refrigerator section warms up, cooling is being produced somewhere. The next question is whether cold air cannot reach the warm section, that section is not being told to cool, or refrigerant is not being distributed correctly.
The diagnosis usually starts in three directions:
A similar symptom can have a different cause on another model. These branches help choose the next check; they are not a reason to order a part from the symptom alone.
These observations do not finish the diagnosis, but they can eliminate several expensive guesses before service begins.

The same temperature split led to different next checks because each case supplied a different discriminating clue.

The evaporator fan was trapped in ice near the drain area, while a separate drain heater measured open. A motionless fan was not enough to condemn the motor.
No supply reached the fresh-food compressor after the board and start relay were replaced. The next question became whether the universal board was configured for the exact model.
After more refrigerant was added, frost reached the compressor return line, pointing toward excess charge. The new clue still did not explain the original problem.
Pressure, airflow and electrical observations are useful only under the conditions in which they were taken.
This order reduces the risk of replacing a good fan, board or compressor.
Move to the sealed system only after the accessible airflow, defrost and control branches have been separated.
The expert conclusion is to separate airflow, defrost and control faults before opening a sealed-system branch. If the safe checks did not explain the temperature split, you can compare this temperature pattern with the refrigerator symptom guide. The local page helps prepare a visit; model-specific measurements determine which of the documented branches applies.

Not in every design. A dual-system or valve-controlled refrigerator can have a section-specific compressor or refrigerant-distribution fault.
No. Ice, a blocked return, a fan problem and even testing with another door open can produce the same impression.
It may temporarily restore airflow if ice is blocking it, but it does not repair the reason the ice formed.
