Dinosaur Electronics Furnace & A/C Control Boards

Dinosaur Electronics: Precision-Engineered RV Furnace & A/C Control Boards

When an RV furnace stops igniting or a climate control system starts behaving erratically, the culprit is often a failed control board. Dinosaur Electronics has built its entire reputation on solving exactly this problem — producing high-reliability replacement circuit boards that RV technicians and owners have depended on for decades. Their Furnace & A/C Control Boards represent the heart of that mission: rugged, precisely engineered electronics designed to restore heating and cooling systems to full operation.

A Legacy Rooted in Electronics Expertise

The founders of Dinosaur Electronics have been in the electronics industry since the late 1950s and early 1960s, with experience testing, repairing, and manufacturing for companies supporting the mainframe computer industry — including NASA's Ames Research Center. Around 1990, the company entered the RV circuit board industry, and by 1993 they were designing and manufacturing high-reliability circuit boards specifically for RV furnaces, water heaters, refrigerators, and generators. That deep technical background is reflected in every board they produce.

The UIB Series: Universal Ignitor Boards Built for the Real World

Dinosaur Electronics is widely recognized for its UIB series of universal ignitor boards , which are engineered to serve as drop-in replacements across the most common RV furnace brands. Models like the UIB-S and UIB-L are designed as universal replacements for Suburban, Atwood, and Dometic furnaces. This cross-compatibility is a major advantage for RVers on the road, where finding an exact OEM board may not always be practical.

Dinosaur's universal 12-Volt DC ignitor boards are certified by Testing Engineers International to meet UL 372 and UL 353 specifications for use in the RV industry. That independent certification matters — it means each board has been validated to recognized safety standards, not just bench-tested internally. The universal ignitor boards are all electrically identical but mechanically different for convenient installation, and these rugged boards use double-sided plated through-hole technology for added reliability. They are fused to protect the board from short circuits in the NC and valve circuitry.

Safety and Diagnostic Features That Set Them Apart

Dinosaur Electronics builds meaningful safety intelligence directly into their furnace control boards. Powered by 12V DC, the board sends signals to open the gas valve and emits a high-output voltage to create an ignition spark. It incorporates a 15-second ignition delay designed to purge any unburned gas from the combustion chamber — a feature that ensures safer and more reliable ignition by eliminating the risks associated with gas buildup.

A two-color LED monitors the NC and valve terminals to let technicians know when there is power to the board (green) and when there is power for the valve (red). The delayed 3-try ignitor boards also feature 20-second purge cycles and local flame sense, and incorporate an option jumper for added flexibility.

For Park Model RV applications, the Dinosaur 24VAC Fan Control Ignitor Board is designed for Park Model furnaces, with fuse protection and a 3-try operation that shuts the fan motor off a minute and a half after the third ignition attempt fails to sense a flame.

Why RV Technicians Trust Dinosaur Electronics

Today, Dinosaur Electronics makes 46 different kinds of replacement circuit boards and 15 different testers, with their product line expanding each year based on direct feedback from the service industry. Their products are carried by over 1,600 dealers. That network is a testament to how deeply embedded Dinosaur Electronics has become in the professional RV service community. Whether you are a seasoned technician or a first-time DIY repairer, their furnace and A/C control boards are engineered for straightforward installation and long-term performance.
