Description
Product Overview
The HLTIT Refrigerator Control Board is engineered specifically for recreational vehicle (RV) refrigeration systems. Built around the model number 3316348.900, this board integrates a dual‑voltage power module that accepts both 120 V AC and 12 V DC sources, allowing seamless operation whether the vehicle is plugged into shore power or running on battery. The board measures 6.85 × 5.63 × 2.8 inches and weighs just 10.9 ounces, making it compact enough to fit into tight appliance compartments while still delivering the robust performance required for continuous cooling cycles.
High‑quality components are layered and inspected to ensure moisture resistance, a critical factor for appliances exposed to the varying humidity levels encountered on the road. The board’s seven bottom connection ports are clearly labeled, simplifying wiring and reducing installation time. Each port is designed to handle the current demands of the refrigerator’s compressor, evaporator fan, and temperature sensors, guaranteeing stable operation even under heavy load conditions.
Manufactured by HLTIT, a brand known for reliable automotive and RV parts, this control board carries an impressive 4.9‑star rating from 18 verified customer reviews. It ranks #53 in the RV Refrigerator Parts category on major e‑commerce platforms, reflecting its popularity among RV owners seeking dependable cooling solutions.

Usage
This control board is ideal for a variety of RV refrigeration scenarios. Whether you are traveling across the United States, camping in remote national parks, or living full‑time in a mobile home, the board ensures your refrigerator maintains consistent temperatures for food preservation. Its dual‑voltage capability means you can rely on shore power at campgrounds, generator output, or the vehicle’s battery system without needing additional converters.
Installation is straightforward for both DIY enthusiasts and professional service technicians. The seven connection ports align with standard RV refrigerator wiring diagrams, and the board’s compact dimensions allow it to be mounted directly onto the existing control panel without extensive modifications. Users have reported successful replacements of older boards that featured ten ports, as long as the original board did not belong to the “293” series, which uses a different connector layout.
Beyond typical RV use, the board can also serve in mobile food trucks, off‑grid cabins, and marine refrigeration units that share similar voltage requirements. Its moisture‑resistant construction protects against condensation that can develop in humid climates, extending the lifespan of both the board and the refrigerator it controls.
