Mandatory diagnostic disclaimer
This tool organizes observations into possible causes and confirmation tests. It does not provide a confirmed diagnosis, replace manufacturer information, or authorize unsafe operation, component replacement, or refrigerant adjustment.
Pattern summary
The selected high/normal/low pattern does not cleanly support one cause; verify before adjustment or replacement.
Qualification
Selected values show tendencies only. Verify before adjustment or replacement; possible causes are not confirmed diagnoses.
Next Best Test
Verify airflow, load, staging, refrigerant selection, probe placement, pressure accuracy, and stabilization. If head pressure moves while suction pressure and both line temperatures remain stable, verify instrumentation early; do not call it TXV hunting.
