Description
This is the genuine Dometic temperature probe CFX335-CFF45C/D for Dometic fridges and freezers, listed under part number 4450021668. Because it is made or supplied by Dometic, it matches the original fit, finish and specification.
How this part works
Sensors tell the control board what is happening inside the fridge, from temperature and water level to door position. A faulty sensor often produces an error code rather than an obvious symptom.
When to replace it
- An error code pointing to the sensor circuit
- Incorrect temperature or over-filling
- A cycle that will not start or stops early
