The 47-100436-05 is a genuine OEM control circuit board designed for Rheem, Ruud, and Protech air handler systems. This microprocessor-based board serves as the reliable “brain” of your HVAC air handler, ensuring precise operation and efficient performance.

Key Features

• Microprocessor Precision Control: Manages inducer motor, blower fan motor, hot surface ignitor (where applicable), and gas valve functions with accurate timing and sequencing.
• Comprehensive Safety Monitoring: Oversees trial for ignition, flame sensing, pressure switches, limit switches, and automatic lockout protection. Provides 100% gas shutoff on ignition failure.
• Durable & Protected Design: Built-in reverse polarity protection and robust construction for long-term reliability in demanding HVAC environments.
• Standard 24 VAC Thermostat Compatibility: Works seamlessly with common thermostats for straightforward integration.
• Updated Retrofit Design: Replaces earlier versions (such as 47-100436-04) with improved features and included harness options in retrofit kits.

Benefits

• Restores Reliable HVAC Operation: Quickly fixes issues like blower motor failures, ignition problems, or erratic fan performance, getting your system back online with factory-level performance.
• Improved Efficiency & Safety: Precise timing (blower ON/OFF delays) optimizes energy use and protects components from damage.
• Easy Professional Installation: Direct OEM fit minimizes downtime for HVAC technicians. Plug-and-play connectors and clear wiring points speed up replacement.
• Peace of Mind: Genuine Rheem-manufactured part meets strict OEM specifications, backed by manufacturer testing and warranty support.

Compatibility

This control board is compatible with various Rheem and Ruud air handler models, including series such as:

• RHSA
• RHSL
• SHSL
• AHSA
• AHSL
• And additional models using UTEC controls (e.g., 1139-160 series)

It is a perfect replacement for older boards in single-stage air handler systems. Always verify your exact model and consult a licensed HVAC technician for installation.

Note: Professional installation by a licensed HVAC technician is strongly recommended. This is an electrical component—proper wiring and safety procedures are essential.
