Rheem-Ruud PD442006 Fuse Link

The Rheem-Ruud PD442006 Fuse Link is a critical thermal safety component engineered for high-limit protection in residential and commercial HVAC systems, specifically within gas-fired water heaters and air handler units. This OEM Rheem replacement part is calibrated with a 285°F temperature rating, designed to provide a fail-safe open circuit when internal temperatures exceed safe operating parameters. Featuring a durable copper construction and a ceramic base, it ensures reliable electrical conductivity and heat resistance under heavy-duty cycles.

For field technicians, the PD442006 is a direct substitute for legacy parts including 44-20037-04, 44-20212-03, and 8611-5513. Its standard 3/16-inch mounting hole allows for precise, secure attachment to existing brackets, ensuring the sensor remains properly positioned for accurate temperature detection. With a resistive rating of 25 Amps at 120V, this fuse link maintains the structural integrity of the furnace or water heater control circuit, preventing catastrophic component damage during a high-heat event. Using a genuine HVAC thermal fuse ensures the system stays within manufacturer specifications for safety and performance.

• Precise Thermal Cutoff: Opens accurately at 285°F to prevent overheating and potential fire hazards.
• Broad Compatibility: Serves as a standard Rheem Ruud replacement part for multiple water heater and air handler models.
• High Electrical Capacity: Rated for up to 25 Amps at 120V to handle standard control circuit loads.
• Rugged Build: Features a corrosion-resistant copper link and a high-temp ceramic mounting base.

• What does a fuse link do in a water heater? It acts as a one-time safety device that breaks the electrical circuit if the unit reaches dangerous temperatures.
• Is the PD442006 compatible with other brands? While designed specifically for Rheem and Ruud equipment, it can replace any link matching the 285°F rating and 3/16" mounting specs.
• Can this fuse link be reset after it opens? No, this is a sacrificial component; once it has been triggered by heat, it must be replaced to restore system operation.
