Waeco / Dometic Compatible Thermistor & Paste Kit – 22-3B-103F100D
The thermistor is the small temperature sensor that tells your Waeco/Dometic portable fridge how cold it is. When it fails, the fridge often stops cooling, over-freezes, runs non-stop, or shows a temperature error. This kit is a direct-fit replacement that gets your fridge holding temperature again.
This is the long 102 cm thermistor, which reaches both compartments of a dual-zone unit. When fitting it closer to the compressor, any extra length can be neatly taped or cable-tied out of the way.
What’s in the kit
- 1 × Thermistor (102 cm long-body)
- 1 × Heatsink paste (tube or syringe)
- 1 × Plastic applicator spatula
Heatsink paste is essential for correct operation and is included. Paste brand may vary with availability.
What this kit fixes
- Fridge not cooling or not reaching the set temperature
- Over-freezing or wildly inaccurate temperatures
- Compressor running constantly or short-cycling
- Temperature sensor / error codes on the display
