I had a fire started with something as simple as the converter fan being blocked, it overheated and tripped the breaker.......only thing the breaker didn't blow all the way causing the wires to start burning.
Right on the front of the converter is a sticker that says:
"Blocking the fan can cause a fire".
WHICH I showed and told my RV guest numerous times to please STOP blocking the converter with their bags of clothes obviously to no avail. :R
Since that near catastrophe? Now it's no more mr nice guy. My rules my MH. Don't follow them you are out at the next exit! :B
