Dometic Fridge Fault Codes & Eyebrow Board Problems – RM7 / RM8 / RMD / RMS Series
Meta Description:
Discover common Dometic fridge faults, eyebrow board error codes, and solutions for RM7, RM8, RMS, and RMD series. Identify symptoms, understand issues, and explore replacement options.
1. Introduction
Dometic absorption fridges are popular in RVs and caravans, but like all aging electronics, their control boards and eyebrow panels can fail. Faults often show as error codes on the eyebrow board, clicking noises, or no power. This page guides you through the most common issues, symptoms, and what they mean for your fridge.

3. Common Eyebrow Board Fault Codes
Code / LED Pattern | Meaning / Possible Issue |
---|---|
No lights / blank display | Eyebrow board dead, PCB not powered, blown fuse, wiring issue |
Flashing red / orange LED | Gas valve failed to open, solenoid stuck, flame not detected |
Continuous blinking | Flame rectification failure, spark generator issue |
Green LED flickers | Power supply unstable, PCB overheating, or DC voltage issue |
Combination patterns | User interface error, board mismatch, or older PCB revision incompatibility |
Note: Exact codes vary slightly by model and board revision (older RM7 vs newer RM8).
4. Common Faults & Symptoms
-
Eyebrow board failures
-
Display dead, lights not responding
-
Buttons unresponsive
-
Loose connections or burnt ribbon cables
-
-
Main control board (P860 / P870) failures
-
Fridge clicks but won’t ignite
-
Gas mode fails, only AC works
-
Continuous clicking / “try start” repeated
-
Board overheating / burnt smell
-
-
GV100 Gas Solenoid Issues
-
Gas flow blocked, fridge won’t light
-
Solenoid stuck open or closed
-
Low DC voltage causes weak ignition
-
-
Spark Generator Failures (Separate / Integrated)
-
No spark at burner electrodes
-
Partial spark → flame not detected → PCB shuts down
-
Intermittent start failures
-
-
Wiring & Connection Issues
-
Burnt connectors, particularly after old board fires
-
Corrosion on flame rectification sensors
-
Loose harnesses causing intermittent errors
-
5. Troubleshooting Tips
-
Check eyebrow board LED patterns first.
-
Verify DC voltage to PCB and solenoid.
-
Inspect GV100 solenoid for mechanical blockage.
-
If spark is separate, test spark module independently.
-
Look for burnt cables or connectors, especially if older boards caught fire.
Most common scenario: replacing both PCB and eyebrow board solves the majority of faults.
6. Replacement & DIY Solutions
-
OEM boards are expensive (~€250+), often without warranty.
-
Works across all RM7/RM8/RMD/RMS models using the GV100 solenoid.

7. Call-to-Action
-
Internal links:
-
RM8505 PCB replacement universal for all similar models
-
289-0241-24 vs 289-0241-20 differences, but these can all be replaced with the universal unit
-
Separate spark module page (RMD8555 exception) these are all unnecessary with the universal replacement kit
