Test the resistor of the temperature sensor
- Ohmmeter available.
- Measure the resistance.
- Measured value Bimetallic strip: 0 ohms (passage).
- Measured value 3x PTC sensor: between 60 and 300 ohm.
- Measured value 4x PTC sensor: between 80 and 400 ohm.
- Resistance checked. If the measured value deviates from the specification, consult the customer service.
