Hi again folks, so My Class A has "heated waste tanks" as labeled on the waste tank compartment door. I'm trying to figure out how this works. there's no on\off switch that I can find anywhere . ...
If it has 'heated pads' there are two types 120V AC....usually controlled by plugging them in to an outlet 12V DC....usually a On/Off rocker switch with a 15A fuse in DC dist. panel. On/Off switch is typically by monitor/level panel. Could be on dash.
They have a temp t-stat that will cycle them with switch in ON position. Cycle on at 44*F.....off at 65*F (temp of contents).
The other method is a furnace heat duct that just blows warm air down into tank area when furnace is ON
