Test the resistor of the temperature sensor

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