DIAGNOSIS The LED light has failed or its connection is loose. There is no separate fuse for the light on this model. It's wired into the main switch.
FIX This is almost always a failed LED module. The light is a sealed unit. You must replace the entire LED light assembly. It's mounted near the blade guard.
IF THAT DIDN'T WORK If a new LED assembly doesn't work, the wire connection from the switch is broken internally. This requires tracing the wire harness, which means full disassembly.
HEADS UP The light is not critical for operation, but working in low light without it increases risk. Do not attempt to modify or bypass the light circuit.
