Dometic RM4400 | RM4401 Spare Parts

The Dometic RM4400 and RM4401 are classic 3-way absorption refrigerators that were widely fitted to caravans, camper trailers and motorhomes throughout Australia and Europe. Originally developed under the Electrolux brand before transitioning to Dometic, these refrigerators became a popular choice thanks to their quiet operation, flexible power options and compact installation footprint. 

Replacements for these models would be the RM8501 or RM8505 or the NRX compressor range.

Unlike compressor refrigerators, the RM4400 and RM4401 use absorption cooling technology, allowing them to operate silently on 240V AC, 12V DC or LPG gas. This makes them ideal for both caravan parks and off-grid camping, where gas operation provides excellent runtime without placing demand on battery systems.

Although these models are now considered legacy refrigerators, many remain in service across Australia. As a result, replacement parts remain essential for owners wanting to maintain or restore their original fridge rather than undertake a complete replacement.

Understanding the Models

The RM4400 is the earlier version of the series and features a traditional manual gas ignition system.

Important Operating Information

Like all absorption refrigerators, the RM4400 and RM4401 perform best when the vehicle is parked on level ground. Good ventilation behind the fridge is also critical to ensure efficient cooling performance and safe operation.

When travelling, many owners use 12V operation to maintain temperature, then switch to LPG when camping off-grid and 240V when connected to mains power.
