Dometic RM2453 Ignition System: DSI vs Pilot Light Truth Revealed
Spent three hours yesterday trying to figure out if my 2001 truck camper's Dometic RM2453 uses DSI or pilot light ignition and I'm still completely lost. I've been trying to light what I thought was a pilot light, but I'm having issues with it staying lit and producing adequate heat for cooling. The flame seems very low and blows out easily, even though my thermocouple is reading over 20mv which should be sufficient.
After doing some research, I'm now questioning whether this model even uses a traditional pilot light system. I notice there's no wire going to the gas valve for electronic activation, and the only control appears to be the eyebrow board on top. Some sources suggest these units use DSI (direct spark ignition) instead of a standing pilot.
Can someone clarify definitively whether the Dometic RM2453 uses a pilot light system or DSI ignition? Also, does this model have variable burner output stages, or is it just a single on/off operation? Understanding the correct ignition system will help me focus my troubleshooting efforts in the right direction rather than chasing a pilot light that may not even exist on this model. …more
