Detroit Radiant Furnace & A/C Control Boards

Detroit Radiant Control Boards: Precision Electronics for Heating Systems

When a furnace or heating system goes down, the control board is often the culprit — and getting the right replacement matters enormously. Detroit Radiant Products brings the same exacting engineering standards it applies to its infrared and radiant heating equipment directly to its line of Furnace & A/C Control Boards, making it a trusted source for OEM-grade replacement electronics in commercial and industrial heating applications.

A Heritage Built on Heating Expertise

Detroit Radiant Products is headquartered in Warren, Michigan, where its manufacturing campus spans over 105,000 square feet of production space, including a certified testing laboratory. That in-house testing capability is a meaningful advantage: control boards and circuit boards that carry the Detroit Radiant name are developed and validated in an environment that mirrors real-world heating system demands.

The brand is best known for its Re-Verber-Ray line of infrared and radiant heaters used in garages, warehouses, hangars, and other large commercial spaces. Because those systems rely on precise electronic ignition sequencing, gas valve timing, and safety lockout logic, the control boards at their core must be engineered to tight tolerances — a philosophy that carries over into every replacement board Detroit Radiant produces.

What to Know About Detroit Radiant Control Boards

A furnace or heating unit control board acts as the central "brain" of the system. It manages the ignition sequence, monitors safety switches and pressure sensors, coordinates the blower motor, and triggers fault codes when something goes wrong. For systems originally built around Detroit Radiant components, using a manufacturer-matched replacement board — such as the TP-851 Circuit Board — ensures that all of these functions operate exactly as the system was designed.

• OEM Compatibility: Detroit Radiant control boards are designed to match the original electrical specifications of Detroit Radiant heating equipment, eliminating guesswork during replacement.
• Integrated System Logic: Because Detroit Radiant engineers both the heaters and the control electronics, their boards are tuned to work in concert with complementary components like transformers, pressure switches, and igniters.
• Commercial-Grade Construction: Manufactured in a facility that includes dedicated production lines and a certified testing laboratory, these boards are built to handle the duty cycles of commercial and industrial environments.
• Broad Application: Detroit Radiant control boards are recognized by HVAC distributors and contractors across North America as legitimate replacement components for radiant heating systems.

Choosing the Right Replacement Board

Because Detroit Radiant's catalog in this category is focused and specific, it is important to match the board to your exact heater model. Cross-reference the part number printed on your existing board or found in your unit's service manual before ordering. When in doubt, Detroit Radiant's engineering documentation — available through authorized distributors — provides wiring diagrams and compatibility guides to help technicians make the correct selection.

Whether you are a facility maintenance technician keeping a warehouse warm through winter, or a contractor servicing a fleet of radiant tube heaters, a genuine Detroit Radiant control board is one of the most direct paths back to a fully functioning system.
