What year is your trailer? That may help describing the panel that you are looking for that contains the breakers.
On my '99, the panel is a Magnatek 6300 and is located just below the refrigerator close to the floor. It looks like this:
There is a little plastic slot at the top center of the upper panel of the unit. Use a coin or screwdriver to rotate that slot 90 degrees. That will unlatch the cover and it swings down to open it up.
With the unit open, there are circuit breakers on one side, and standard automotive style fuses on the other. The breakers control any 110vac appliances and outlets in the trailer. The fuses control various 12vdc appliances, and should be labelled. The unit looks like this when opened:
The Magnatek 6300's were used for a number of years in Sunlines, so if your unit is more than a couple of years old, it probably has one, too. If your unit is newer, it may have a different brand or model of panel, but they are all fairly similar in size (about 12"x12" give or take a few inches) and appearance. The method of opening the panel may be a knob instead of the little slot, and the door may open to the left or right instead of swinging down.
To the best of my knowledge, the convertor panels are almost always located:
1. Down low near the floor.
2. On the same side of the trailer as the electric cord hatch (driver's side).
3. Directly adjacent to the electric cord hatch.
In other words, where ever the main electric cord enters the trailer via a little plastic door, inside at about the same location you should find the panel down low near the floor.
BTW, the furnace is 12vdc for the blower and control circuitry. That means the convertor has to be working properly, and on most trailers there has to be a 12vdc battery for the 12vdc appliances to properly work. Some of the newer trailers have better convertors and may not need the battery for this, but it is greatly preferred.
