Product details
The LCD panel on a PU3650 power unit is not just a screen, it is tied directly to the low-voltage board that switches the motor on and off, so a fault here usually affects both what you see and whether the unit responds at all. This module replaces that combined display and control board.
Built for the PU3650 power unit, the model Electrolux sold as the QuietClean, and listed by parts retailers under part 102020 for exactly this platform. A dark or scrambled display, missing run-time or service indicators, or a unit that no longer starts when a wall inlet opens are the typical signs this board has failed rather than the motor or the wiring elsewhere in the system.
- Fits: Electrolux PU3650 power unit
- Type: Combined LCD display and low-voltage control board
- Function: Status readout plus motor on/off switching
- Symptoms it addresses: Blank or garbled display, unresponsive start/stop
Before replacing the board, cut power to the power unit at its breaker for a full minute and restore it. Some display faults on this platform are a stuck logic state rather than a hardware failure, and a clean power cycle clears them without spending on a new board. If the display comes back scrambled or stays dark after that reset, the board itself is the more likely cause.
Because the display and the switching logic share one board on this platform, a screen problem is worth treating as a possible control fault even if the unit still seems to start, since intermittent switching failures often show up on the display first, before they cause a full no-start. Keep the old board until the new one is confirmed working normally, in case a wiring issue elsewhere turns out to be the actual cause. Listed under SKU 102020.
