Graco 24P848 220V Control Board Kit

Reclaim pinpoint pressure and diagnostic control with a brand-new Pressure Control Board (PCB).

1 | Why the Control Board Is the Sprayer’s “Brain”

Modern Graco airless rigs rely on SmartControl electronics to sample line PSI hundreds of times per second, adjusting pump speed so your fan pattern never surges or tails. Heat, voltage spikes, and solvent vapor eventually fatigue surface-mount components; the result is erratic pressure, phantom alarms, and stiff trigger pull caused by unstable flow. Installing the fresh Graco 24P848 board restores factory tolerances, bringing dead-steady atomization back to every stroke.

2 | What’s Inside the Kit

• Conformal-coated 220 V logic board with pre-programmed firmware
• Shielded five-wire harness and keyed connector block
• Thermal interface pad plus stainless mounting screws
• Quick-start card with QR code linking to full PDF service manual

3 | Fast Four-Step Installation

1. Unplug sprayer, relieve pressure, and remove side shroud.
2. Disconnect harness; back out four PCB screws and lift the old board.
3. Seat the new PCB onto standoffs, add thermal pad, twist screws to 12 in-lb.
4. Plug harness, replace shroud, power up, and run test-prime—done.

With a magnetic screwdriver and ten quiet minutes, any tech—or meticulous DIYer—can execute the full swap curb-side.

4 | Compatibility Snapshot

• Ultra 490 PC Pro 220 V • Ultra Max II 495 220 V • Classic 390/395 PC 220 V
The board also retrofits earlier 230-volt ST Max frames after a simple jumper move outlined in the install sheet.

5 | Performance Benefits You’ll Notice

• Smoother Atomization — microadjusted pump speed eliminates zebra-striping on broad walls.
• Instant Prime — stable voltage lets the motor pull high-viscosity coatings in seconds.
• Accurate Error Codes — clean firmware ends false E-30 and E-50 shutdowns.
• Lower Amp Draw — efficient FET drivers reduce heat, extending motor life.

6 | Preventive-Maintenance Pairings

Combine the PCB swap with a fresh pressure transducer and inlet strainer; a clean signal loop ensures SmartControl’s full accuracy. Crews running heated hoses should check cord insulation—clean voltage in plus stable logic out protects every paint spraying equipment investment.

7 | Field-Tested Success Stories

“The new board cured random PSI drops on our Ultra 495—fan stayed locked at 2200 PSI for eight hours straight.”
— Valentina S., Cabinet-Finish Specialist

“Had two Classics throwing E-30 alarms; swapped each 24P848 in under 15 minutes, zero issues since.”
— Dylan R., Rental-Fleet Supervisor

8 | OEM vs. Aftermarket Electronics

Copycat PCBs may boot, but cheap MOSFETs and no-name EEPROMs drift quickly, re-introducing pressure swings and risking motor burnout. Genuine Graco logic meets UL, CE, and FCC noise standards, safeguarding both job-site safety and equipment warranty.

9 | Inventory Tips for Fleet Managers

Keep one control-board kit per four sprayers on the truck. Label carton dates and firmware rev to match each rig’s service notes; that discipline slashes diagnostic time when a unit faults mid-project.

10 | Order Now—Spray Like New Tomorrow

Hit “Add to Cart,” choose your preferred shipping speed, and store a 24P848 in every service kit. The next time electronics falter, you’ll be back on the wall—laying glass-smooth coats—long before competitors track down a local repair shop.
