Is this the same quality as the WFCO OEM board?

This aftermarket board is manufactured to identical electrical specifications. It provides the same 55A output and 3-stage charging as the WFCO original at significant cost savings.

Do I need the whole power center or just this board?

If only the converter section has failed (which is most common), replacing just the board saves hundreds versus replacing the entire WF-8955 power center. If the enclosure or distribution panel is damaged, full replacement may be necessary.

What is 3-stage charging and why does it matter?

Bulk mode rapidly charges a depleted battery. Absorption mode safely tops off the last 20%. Float mode maintains full charge indefinitely without overcharging — critical for batteries in storage. Single-stage chargers can boil batteries dry over time.

How do I avoid miswiring and damaging the board?

The board uses standard color coding — Black is hot (line) and White is neutral. Always disconnect shore power AND battery before working. If your existing wiring uses non-standard colors, verify each wire with a multimeter before connecting to prevent short circuits.

How difficult is installation?

If you are comfortable with basic electrical work, it is a 15-30 minute job. The board uses the same mounting and connectors as the original. Always disconnect ALL power sources first for safety.

Does this board include a cooling fan?

The board includes cooling provisions. Ensure the power center ventilation openings remain unobstructed for proper heat dissipation during operation.

What output voltage should I see after install?

A healthy board should read 13.2-14.4V DC under normal load. Bulk charge peaks around 14.4V, then drops to ~13.6V float. A reading outside this range usually indicates a wiring issue or failed converter.

Product Overview

The iFJF WF-8955 MBA RV Converter Main Board is a direct, drop-in replacement for the WFCO WF-8955 and WF-8900 series power centers (including Parallax 7145/7155). It restores reliable 120V AC-to-12V DC power conversion and 55-amp battery charging so your lights, pumps, fridge, and house battery all work like new — without rewiring or replacing the entire power center.

Engineered to match the original board's mounting points and connectors, this aftermarket main board delivers identical 55A output and 3-stage smart charging at a fraction of the cost of a full WFCO replacement unit.

Key Features

Direct Drop-In Fit: Exact replacement for WFCO WF-8955 MBA / WF-8900 series converter boards — same connectors, same mounting, no rewiring required.
55 Amp / 12V DC Output: Reliable power conversion for all 12V RV systems — lighting, water pump, furnace, slides, and more.
3-Stage Smart Charging: Bulk → Absorption → Float. Rapidly recharges a depleted battery, safely tops off, then maintains full charge without boiling the battery dry in storage.
Standard Wire Color Coding: Black = hot (line), White = neutral — clearly marked to prevent miswiring damage. Always verify with a multimeter before energizing.
Built-In Protection: Overvoltage, overcurrent, overload, short-circuit, and thermal protection guard both the board and your RV battery.
Cooling Provisions: Includes cooling provisions for proper heat dissipation — keep the power center vents unobstructed during operation.

Compatibility
