What's wrong?
The fuse box on 2016-2020 Hme 1871, Sfo, and AF1 emergency vehicles is the electrical distribution point for protected circuits. It holds fuses and circuit breakers that are designed to stop excess current before wiring or connected equipment overheats. On a fire truck, that box has to stay sealed because moisture and road debris do not belong around live electrical contacts.
On affected vehicles, the fuse box is missing an O-ring seal. That seal is a small rubber ring that closes the gap around the fuse box housing. Without it, moisture or contaminants can get inside the box, reach the fuses and terminals, and create fault codes or heat damage. Hme's investigation found returned units with melted or charred fuse box components.
There is no warning sign before failure. If the issue shows up, an operator or service crew can see electrical fault codes, but the missing seal itself is not something the driver is expected to notice during normal operation.
