What's wrong?
In recall 19V274, the part at issue on 2011-2019 Nova Bus Lfs buses is the electrical connector that feeds power to the engine door fan. That fan helps move air around the engine-door area, and the connector is supposed to carry the fan's electrical current without heating up.
On affected buses, the connector is undersized for the current the fan draws. That is a design issue: the connector is asked to carry more electrical load than it was built to handle. As the bus operates, that overload heats the connector over time. If the heat builds far enough, it can damage the fan and door area and start a vehicle fire.
There is no warning sign before failure. An operator or maintenance crew should not count on a warning light, smell, or visible damage before the connector overheats.
