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>

vert simple.

Wow. Ordered it on a Wednesday got it in 2 days....amazing....and to top it off my mandrel bent ss tubing was packaged infinitely better then I would of imagined. The price was amazing. I literally have no complaints. I will definitely order again. I will say that items on their website were not labeled well so I used vibrants website to look up part numbers so I could get the right parts. Search engine wouldn't bring up items via part number. Kinda confusing but for all I got simply awesome.

Website easy to navigate...best pricing i've found.

Easy

quick and easy ordering.

Fast service even when shipping from the manufacturer. My product got to me in 3 days and it works great! Ordered an Odyssey PC1200 battery which was 20% cheaper than anyone else, with shipping included. Shipping information is a little slow on getting the tracking number, but their staff is efficient and friendly. Would definitely do business with them again.

Wow, cheapest price I could find anywhere. AND, it shipped the same day. Amazing service. Thanks Autoplicity!

Good

This site had the lowest pricing out of any website that was advertising the same product on Google shopping. The shipping cost was very resonable and the parts arrived in two days.

I have found the BEST price on a part clearly overpriced at other online stores... Excellent customer service knowledgble of mustang performance! Will surely buy again!

I placed an order and 2 days later it was at my door!!! Very fast shipping and easy to navigate website! I would definitely recommend this site to all my friends. Keep up the great job!
