What's wrong?
The Miller Enpak A60GBH on the 2021-2022 Maintainer Crane W/ Service Body is an auxiliary power unit installed on the service body. It supplies onboard electrical power for jobsite equipment, and its output inductor is an electrical coil inside the power module that helps manage the current coming out of the unit.
On affected units, the output inductor was built incorrectly. Instead of staying clear inside the power module, it can touch a metal air baffle or the Enpak frame while the unit is operating. Metal-to-metal contact at that point can create an electric arc, which is uncontrolled electrical current jumping where it should not go.
There is no warning sign before failure. The problem can happen during Enpak operation without a smell, noise, light, or other clear signal first.

Both model years use the Miller Enpak A60GBH auxiliary power unit tied to this electrical-system recall.

What's the safety risk?
An output inductor contacting the Enpak frame while it is operating can create an electric arc and increase the risk of a fire. Warning signs are not reliable, so if your VIN is included, schedule the recall repair before relying on the Enpak for work. Repair is free at any franchised Maintainer dealer.
