Ryobi Ryobi RY40290 40V HP Brushless Whisper Series Jet Fan Blower TRIGGER ISSUE Error Fix: Variable Speed Trigger Not Responding Properly

The variable speed trigger does not respond, responds intermittently, or is stuck at one speed. The trigger controls motor speed through a variable resistor or Hall effect sensor. If the trigger does not respond at all: check the battery connection, try a different battery, and verify the safety lockout button is not engaged (most Ryobi blowers have a lockout button that must be pressed before the trigger will work). If the trigger only works at certain positions or jumps between speeds erratically, debris may be inside the trigger mechanism — compressed air blown into the trigger area may help. If the trigger is physically stuck (does not spring back when released), the return spring may be broken or debris is jamming the mechanism. Do not use the blower with a stuck trigger — it is a safety issue. Trigger assembly replacement requires partial disassembly of the handle. Contact Ryobi warranty service if within the warranty period.
