Detroit Radiant TP-222A Sensor Wire

The Detroit Radiant TP-222A Sensor Wire is a critical high-temperature ignition component designed for Re-Verber-Ray infrared heaters. This specialized flame rod sensor wire facilitates the essential feedback loop between the flame sensor and the ignition control module, ensuring the presence of a flame is accurately detected for safe burner operation. Constructed with high-grade insulation to withstand the intense ambient heat of the burner box, the TP-222A prevents signal degradation and false flame failures. For contractors performing HVAC preventative maintenance, replacing brittle or scorched ignition lead wires is vital to avoid integrated furnace control lockout codes. This genuine Detroit Radiant replacement part ensures precise impedance and continuity, maintaining the integrity of the flame rectification circuit. Compatible with various tube heater models, this wire utilizes a standard female spade terminal for a secure, low-resistance connection to the flame ionisation rod.

• Heat-Resistant Insulation: Engineered to endure high-temperature environments without cracking or losing dielectric strength.
• Precise Signal Transmission: Minimizes electrical noise to ensure the ignition module receives a clear microamp signal.
• Direct OEM Fit: Designed specifically for Re-Verber-Ray systems, eliminating the need for field modifications or soldering.
• Fast System Diagnostic: Replacing worn sensor wires often resolves intermittent flame rectification issues and nuisance shutdowns.

What causes a flame sensor wire to fail?
Continuous exposure to high thermal cycles causes the insulation to become brittle and crack, leading to electrical shorts or high resistance that interrupts the flame signal.

Can I use standard primary wire as a replacement?
Standard wire lacks the specific temperature rating required for infrared tube heaters; using non-OEM leads can result in insulation melt and cabinet fires.

Does this fit all Detroit Radiant heaters?
The TP-222A is designed for specific infrared series utilizing remote flame sensing; always verify your heater wiring diagram for the correct part number.
