Durst CLS/VLS 501 Fan

My Durst L1200 VLS501 head has a non-operational cooling fan. I took the beast apart, and the fan has 3 wires connected to a "Phase Shift Capacitor" PCB, which has 3x 10uF capacitors and not much else on the board. The board has 2 wires going in (24V and Ground).

I tried powering the fan with a DC power supply, but I'm thinking the fan needs more than just 24VDC to run.

Any ideas? I can't find a replacement fan anywhere.

Thanks,
