Truma Vario Control Panel fuse location

[RustyMD]

Where is the fuse for the Truma Vario Control panel? My Truma Vario Control Panel will not turn on. It might be the fuse.  I have Hull #1304 a 2023 Legacy Elite II.

I don’t know where the fuse is but I would start by removing the control panel and check the connections in the back.  There may be a breaker in the panel under the small dinette on the front of the seat. Everything else on DC is working? Lights, fan? Switch on the hot water turned on? The only time I have seen my Truma display go dark is when I turn off the house batteries. Battery voltage ok?

You can access the back from a porthole in the pantry. I didn’t see any fuses back there and nothing was disconnected. I looked at the 12 volt fuses under the dinette and all seemed fine. I pulled one that said heater I believe and it was OK. I’ll probably change any that reference any HVAC stuff but was hoping to find a secret fuse that was the one that powered the controller. Maybe it gets its power from the individual components. Thanks.

You might want to check the actual wire connection, I had one of the spade connectors come loose and resolved a similar electrical problem by simply squeezing the connector with pliers for a tighter fit.
