Question
How to diagnose faulty climate control temperature sensor in HVAC systems?
Answer
Compare sensor readings with ambient temperature and test sensor resistance.
Explain
A faulty HVAC temperature sensor causes incorrect airflow temperature. CHEPQ multimeters test sensor resistance (varies with temperature) and tools compare readings to external ambient sensors—replacing the sensor restores accurate climate control.
