Dynarex Replacement RPOC-23C5P 5L Concentrator Light Panel Wiring Harness – 5-Pin, White, 1 EA

The Dynarex Replacement RPOC-23C5P Light Panel Wiring Harness (5-Pin) restores proper illumination and signaling functions to compatible Dynarex 5L oxygen concentrators. If indicator LEDs flicker, fail to light, or only work when the front panel is flexed, the original harness is usually fatigued at the solder joints or oxidized at the connector — this replacement brings the panel back to reliable operation.

This harness is the exact style used for the front light panel assembly and includes a 5-pin connector pre-terminated to matched wiring, ensuring correct pin alignment without rewiring, crimping, or soldering. The goal is low-frustration replacement and minimal downtime.

Common failure symptoms

• LED indicators dim, intermittent, or dead

• warnings fail to illuminate when triggered

• light panel only works when “pressed just right”

• wiring jacket cracked from heat & vibration cycles

Where it’s used

• concentrator refurbishment & servicing

• restoring consistent indicator lighting for rental fleets

• replacing damaged harnesses from shipping or rough handling

• routine preventive maintenance when light panel reliability matters

Service notes

• disconnect AC & allow internal capacitors to discharge before access

• avoid twisting the harness under the PCB — tension fatigue is usually what killed the old one

• match connector orientation; incorrect insertion can blow indicator circuitry

Compatibility

• Dynarex 5L concentrators using 5-pin light panel wiring (RPOC-series)

What’s included

• 1 × replacement 5-pin wiring harness for light panel indicators

Replacing a failing harness keeps status lights honest — when oxygen delivery is critical, bad indicators are non-negotiable.
