Central Vacuum Circuit Board for Frigidaire FRGCVP520 / PU7502A

A central vacuum power unit does not know when to run on its own. It waits on a low-voltage signal from a wall inlet, a hose handle switch, or a remote keypad, and the circuit board is what reads that signal and closes the relay to the motor. This board is built for the Frigidaire FRGCVP520 power unit, sold elsewhere under the PU7502A designation, a 120 volt control module in retailer listings.

Fits Frigidaire FRGCVP520 and PU7502A power units. When a Frigidaire-platform unit refuses to start, starts and then cuts out on its own, or ignores the hose handle while the wall switch still works, the board is a far more common culprit than the motor itself, and it costs a fraction of a full power unit swap.

• Fits: Frigidaire FRGCVP520, PU7502A power units
• Function: Low-voltage signal sensing and motor relay control
• Symptoms it addresses: No start, intermittent start, unresponsive hose handle
• Note: Confirm your existing board's mounting holes and connector layout match before ordering

Before ordering, compare the wiring harness connector on your existing board to the photos for this part. Even within one production platform, connector counts and layouts can vary between build batches, and confirming the match before you begin the swap avoids a return trip mid-repair.

Boards on this platform tend to fail from age rather than any single event, most often relay contacts pitting after years of daily switching cycles, so a unit that ran reliably for years and then goes unresponsive overnight points squarely at the board. Listed under SKU 102041.
