Dinosaur Electronics

<h3>About Dinosaur Electronics</h3><p>Based in Lincoln City, Oregon, <strong>Dinosaur Electronics</strong> has built a well-earned reputation as one of the most trusted names in replacement electronic control boards for RV appliances. For RV owners and service technicians alike, the brand represents a reliable solution when the original control electronics in a rig fail — offering direct-replacement boards engineered to restore full functionality without the guesswork.</p><p>What sets Dinosaur Electronics apart is its singular focus: rather than manufacturing the appliances themselves, the company engineers the electronic brains that make those appliances work. This specialization means their engineering team develops deep expertise in the control logic, pinouts, and failure modes of the RV appliances their boards are designed to replace. The result is a product line that RV service centers have come to depend on for consistent, reliable performance.</p><h3>RV HVAC &amp; Climate Control Solutions</h3><p>A significant portion of the Dinosaur Electronics catalog addresses the climate control needs of modern RVs. Their <a href="/7317-dinosaur-electronics-hvac-heater-control-valve-6860">HVAC Heater Control Valves</a> are among their most popular products, providing precise regulation of coolant flow to keep cabin temperatures comfortable whether you're parked in the desert or at a mountain campsite. Closely related are their Ventilation Parts &amp; Accessories, which round out the airflow management side of RV climate systems — essential for maintaining air quality and comfort in an enclosed living space.</p><p>For those dealing with a malfunctioning rooftop air conditioner or propane furnace, Dinosaur Electronics' Furnace &amp; A/C Control Boards are a go-to replacement option. These boards are designed to match the original specifications of many popular RV furnace and air conditioning units, making them a practical choice for DIY repairs and professional service centers alike. Their <a href="/7317-dinosaur-electronics-hvac-control-module-47959">HVAC Control Modules</a> further expand this coverage, providing the electronic interface between thermostats and climate equipment across a range of RV platforms.</p><h3>RV Refrigerator Electronics</h3><p>Beyond HVAC, Dinosaur Electronics also produces control electronics for RV Refrigerators — the absorption-style units common in motorhomes and travel trailers. These refrigerators rely on precise electronic control to manage ignition, temperature regulation, and fault detection, and Dinosaur Electronics' replacement boards are built to handle those demands reliably.</p><h3>Exceptional Technical Support</h3><p>One hallmark of the Dinosaur Electronics brand is its commitment to customer and technician support. The company provides troubleshooting tips, wiring diagrams, pinout references, and installation instruction sheets to help ensure a smooth repair experience. This depth of documentation is a major reason why professional RV technicians and serious DIYers consistently turn to Dinosaur Electronics when an OEM board is no longer available or simply too expensive to source.</p><p>Whether you're a full-time RVer keeping your home-on-wheels running smoothly or a shop technician looking for dependable replacement electronics, Dinosaur Electronics delivers the quality, compatibility, and support that demanding RV repairs require.</p>

Product Details

The Dinosaur Electronics 3850415.01 is an aftermarket replacement control board designed specifically to replace Dometic part number 3850415-xxx in gas absorption refrigerators. This lower control board serves as the main circuit board, controlling the ignition and operation of the propane system as well as power to the AC element.

Key Features:

  • Direct replacement for Dometic 3850415-xxx Black Box Boards
  • Built-in fuse protection with 3-amp fuse for added board protection
  • Variable temperature adjustment feature for fixed-temp refrigerators
  • 2-way or 3-way operation capability
  • CHECK light indicator that illuminates after each failed ignition attempt
  • Automatic 3-try ignition cycle that repeats at 30-minute intervals if no flame is detected
  • DC voltage protection: DC element drops out and mode light flashes if voltage falls too low for more than 10 seconds
  • Easy-to-remove cover included
  • Three-year manufacturer warranty

This replacement board requires an external igniter for propane ignition and offers enhanced functionality compared to the original equipment, including the adjustable temperature control that provides greater flexibility for RV refrigerator operation. Made by Dinosaur Electronics, a leader in RV replacement circuit boards with decades of experience since 1990.

Important: Use this board only to replace Dometic 3850415-xxx boards. Do not attempt to replace other part numbers with this board.
