Safety first: Disconnect power before accessing internal sensors.

Steps to check and address E37:

Locate secondary NTC: On washer-dryer models, this may be on the air duct or condenser. Refer to Siemens documentation for exact location.
Inspect and test: Check connector and wiring, then measure resistance. Replace the sensor if readings are out of spec.
