good morning.............question: our 07 knight has this feature that is called "system heat", with a switch that is located on monitoring panel in coach. it is supposed to have a small heater in the water bay, that you use in cold weather. the owner manual shows the heater, which to me looks like a "milkhouse" style heater. when i open the bay door, i don't see anything that resembles this. the question is, is the heater BEHIND the white plastic panel in the back of the bay? or is it something i should actually SEE?..............someone told me it was behind the panel. we have never used this function, as when it gets cold, i winterize until i get to a warmer climate. AND, if this unit is behind the panel, is there anyway to tell that it is working?..........thanks in advance

Mine is behind the white panel as you mentioned. The only way I know that is because when it was on, and I stuck my hand back there, I could feel the air being blown. Mine wasn't blowing warm air, so I don't trust it. I bought a small heater and plugged it in for that bay. I brought this up some time back . I'd still like to get the bay heater working properly sometime. I will be watching this post. It's in a bad spot to see it. I'm going to get my mirror and take a look behind there, I keep forgetting, lol, beings I have the other heater.
Have a Good Day.

As larry mentions, it's behind the white plastic panel.

There is a snap disc (about the size of a nickel and mine is mounted on the plastic panel), and that is the thermostat to control it. You can unscrew the snap disc, put it in a zip lock bag with wires still connected and carefully put it in ice water. Don't let snap disc get wet, but this should turn on the heater to see if it's working. If it doesn't work, there is many threads on the fix here, including how to get to the fuse inside the heater.

The heater is 12 volts so don't expect a lot of heat, but it's kept my wet bay above freezing when outside temperature was in the low 20's.

Mine is just behind the black and grey water drains and is mounted to the deck so I can see it below the white panel. I am in cold weather with 20s coming this way so I turned it on and using an infrared temp gun checked to see it was producing heat.

I keep a remote reading thermometer with the sender in the wet bay when temps are going to go below freezing. When the system is working correctly the wet bay temp will average about 42-44 degrees. Nice is that I can put the display in the house when we're home and monitor the status as needed.

I put a thermometer in my wet bay last night and it was steady about 65, outside dropped to 28. I think the heater ran from the time I turned the switch on until I flipped it off in the morning. I also stuffed some rags around the water hose and sewer hose where they enter the wet bay to block the flow of air in/out of the bay. I may have a bad snap disc...wonder where it is hiding.

from what I've read on here and elsewhere, if yours works, you are in the small lucky group

On my 07Knight the heater is just behind the white panel and down, You cant miss it if you are looking below the white panel.

Mine is on the forward wall of the water bay, and it's about 6 inches square and 4 inches deep. It's a 12vdc heater so 1) if will eat your batteries if you're not plugged in or running, and 2) it doesn't put out a lot of heat but it puts out enough to fight off 25*F outside weather. Mine work as advertised. There will be a snap disc to control it; it looks like a nickel with two wires connected to it, mounted on the same wall as the heater. The snap disc closes at like 37*F and opens at 46, sumpin like that.
