Some propane detectors feed a solenoid on the propane tank feed that shuts off the propane. If equipped the propane detector must have a steady green LED before the solenoid is energized.
Look for solenoid next to the propane regulator.
Make and model of your rig?
Make, model and age of propane detector?
He has a 2020 purchased new. LP solenoid controlled LP detectors went away more than 20 years ago. The Op's problem is, his LP fails to stay lit. As he found out, the Check Light only tells you the refer failed to either LIGHT and stay Lit. His model was NOT farmed out to Europe. It is an American designed model for the USA. There are a multitude of things that will cause these type problems
1. Lack Of LP or LOW LP pressure
2. IF refer in a slide room, the rubber LP hose may be kinked restricting LP flow
3. Bad Spark electrode
4. Bad main control module
5. LOW battery voltage
