Check Before Replacing
- With power disconnected, inspect the thermostat and wiring for visible damage or burnt terminals.
- Test thermostat continuity only according to the applicable service documentation; an open reading at room temperature may indicate a failed thermostat, but operating-temperature specifications must be verified before condemning the part.
- Verify that airflow and exhaust are unobstructed before replacing a limit thermostat, since restricted airflow can cause repeated high-limit operation.
