Dometic 4450027311 is an OEM RTX2000 12V PCB circuit board kit for the Dometic RTX2000 system shown in the product photos. This kit is for repairs where the original control board/module needs to be replaced with the correct Dometic service part instead of a generic electronics board.
When this PCB kit is the right repair
This part is typically purchased when an RTX2000 unit has control-board related symptoms such as no power response, erratic operation, failed controls, or a damaged board/connector assembly. The photos show the main control assembly, rear cover, side profile, display board, and wiring connectors so you can compare the physical layout before ordering.
Fitment and part-number checks
- OEM Dometic service part number: 4450027311
- Reference board label shown in photos: RTX 2000 MPCBA-12V
- Compare your original board label, connector locations, wire harness, mounting shape, and RTX2000 model information before ordering
- Not a universal circuit board; connector layout and board revision matter on electronics repairs
What is included
The gallery photos show the control-board assembly and related board/wire components supplied for this kit. Reuse only compatible original hardware and follow the service procedure for your RTX2000 unit.
Helpful buying note
Electronic service parts are highly fitment-specific. If your board label, connector count, or mounting pattern does not match the photos, use ERVP's AI Live Chat with photos of your original board before ordering.
