Rheem-Ruud 46-101496-01 Transformer

When you are troubleshooting a dead furnace or an unresponsive thermostat, the Rheem-Ruud 46-101496-01 Transformer is the reliable OEM solution for restoring low-voltage control. This 40VA HVAC transformer is designed to step down 120V primary voltage to a stable 24V secondary output, powering your integrated furnace control boards, gas valves, and igniters. As a veteran-preferred HVAC 120V to 24V step-down transformer, it serves as the direct replacement for 46-24124-03, 46-24124-04, and 46-24124-05, ensuring a perfect physical and electrical match in the field. This unit features a Class 2 power-limiting design with an integrated 2A external fuse for enhanced overcurrent protection, preventing downstream damage during shorts. The standard OEM four-hole mounting (1-7/8" x 1-1/2" spacing) and 1/4-inch insulated female quick-connect leads allow for rapid installation in tight blower compartments. Whether you are dealing with a blown furnace transformer due to a shorted contactor or a simple component failure, this genuine Protech 46-101496-01 ensures your system maintains a consistent 50/60Hz cycle for mission-critical reliability.

• Universal Compatibility: Engineered as an exact 120V primary replacement for deprecated Rheem and Ruud part numbers including 46-24124-03 and 46-101506-01.
• Integrated Circuit Protection: Features an external 2A fuse to safeguard the secondary 24V circuit against surges and shorts.
• Class 2 Safety Rated: Meets the industry standard for 40VA power-limiting devices used in residential and commercial HVAC applications.
• Contractor-Ready Leads: Pre-crimped with 1/4" insulated female quick connects for secure, vibration-resistant electrical termination.
• Robust Mounting: The four-hole furnace mount provides a stable installation that resists the common humming and vibration issues found in generic universal transformers.

• Why did my transformer fail? High-voltage surges or low-voltage shorts—often caused by a grounded contactor coil or a rubbed wire in the outdoor unit—are the most common causes for a blown 24V transformer.
• Can I use a higher VA transformer? Yes, you can typically upgrade to a higher VA (e.g., 50VA or 75VA), but the 40VA rating of the 46-101496-01 is the factory-standard load for most Rheem gas furnaces.
• How do I test this part? Use a multimeter to verify 120V at the primary side. If 120V is present but you register 0V at the 24V secondary terminals, the transformer has failed and requires replacement.
