Dometic RM46 | RM460 | RM461 | RM66 | RM660 | RM760 | RM77 Spare Parts

The Dometic RM46, RM460, RM461, RM66, RM660, RM66E, RM760 and RM77 are among the most recognised legacy absorption refrigerators produced by Dometic and Electrolux. Commonly fitted to caravans, motorhomes, camper trailers and RVs throughout the 1970s, 1980s and 1990s, these refrigerators were designed to provide reliable cooling using LPG gas, 12V DC and 240V AC power.

Built around Dometic's proven absorption refrigeration technology, these models operate silently without a compressor, making them ideal for caravanning and off-grid travel. While now discontinued, many of these refrigerators remain in service today, creating ongoing demand for replacement parts and servicing components.
