NTC Temperature Sensor Dometic CoolFreeze / ICF — Ref. 4450021852
Genuine Dometic NTC temperature sensor for Dometic compressor coolers and refrigerators.
This NTC sensor (Dometic reference 4450021852) is the replacement temperature sensor for Dometic compressor coolers and refrigerators. An NTC sensor (negative temperature coefficient) measures the internal temperature of the appliance and passes the information to the electronics, which regulate operation.
A faulty sensor can lead to incorrect temperature regulation, an appliance that cools too much or too little, abnormal cycling or a fault code. Replacing it restores reliable measurement and correct regulation.
