The 0138788 controller is the central electronic module that manages the operation of Helix LP sprayers. It receives input from pressure sensors and user controls, then adjusts motor speed to maintain the desired pressure automatically. It also monitors system status and can display diagnostic information.
Over time, controllers can fail due to electrical surges, moisture ingress, or component fatigue. Symptoms include failure to start, erratic motor behavior, inability to maintain pressure, or unresponsiveness to adjustments. Replacing a faulty controller with this genuine Helix component restores precise control and ensures reliable sprayer performance.
