I have exactly same issue on my 2012 Roadtrek Popular 190 Chevy. Someone said it's combined in the inverter, Tripplite in my case, but I can't confirm that so far. I just had a new transfer switch installed and that could be the key to my problem.
For you, from ChatGPT:
On a
2007 Winnebago Adventurer 38T, the
converter (the unit that takes 120 V AC shore power and changes it to 12 V DC to run lights/12 V systems and charge the batteries) isn’t in the engine bay — it’s inside the living area and typically installed near other electrical components. (
Winnebago)
Common Locations for the Converter
Here’s where it’s most often found on Winnebago Adventurer floorplans similar to the 38T:
- Under or near the refrigerator: Many owners report the converter/charger mounted on the floor behind a panel under the fridge or behind a lower cabinet near it. (RV Forum)
- Behind lower kitchen cabinets/drawers: It may be behind the bottom drawer(s) under the stove or sink area— you sometimes need to pull these out to access the converter. (IRV2)
- Lower cabinet face in galley/living area: The official Winnebago operator manual notes the converter is generally installed in a lower cabinet area in the galley, living space, or beneath a bed depending on the floorplan. (Winnebago)
Tips for Finding It
- Look for a metal box with ventilation slots and multiple 12 V wires running into it near the coach’s main electrical panel or breaker area. (Camping World Blog)
- Check access panels or drawers around the kitchen appliances — many converters are tucked in there to stay cool and out of the way. (IRV2)
- A converter is different from the inverter (which turns 12 V into 120 V and, if present, is often elsewhere, like in an outside power bay). (winnieowners.com)
If you want, tell me where your 38T’s kitchen and fridge are located on your floorplan and I can give more precise directions!
