Rocket Espresso PID/Shot Timer Display Assembly
The flickering is typically the result of thermal degradation of the LED driver or filtering capacitors on the internal PID control board. Constant exposure to radiant heat from the boiler causes voltage ripple, which destabilizes the digital output to the display segments. Replacing the integrated module restores the regulated power supply and logic timing for the timer display.

E61 Group Lever Microswitch
If flickering occurs specifically during a shot, the lever-actuated microswitch is likely suffering from internal contact carbonization or mechanical fatigue. This causes 'signal bounce,' where the PID receives rapid, intermittent start/stop pulses, manifesting as a flickering timer. Replacing the switch ensures a clean electrical continuity signal when the lever is engaged.

PID Display Ribbon Cable
The connection between the main Giarner controller and the front-facing display utilizes a multi-pin ribbon cable. Thermal expansion can cause the connector pins to lose tension, resulting in intermittent data transmission and visual flickering of the digits.
