WHITE-RODGERS

White-Rodgers is a manufacturer of electromechanical and electronic controls for heating, ventilation, and air conditioning equipment, with a product history that includes gas valves, ignition controls, relays, thermostats, and related components. The brand is part of Emerson Electric, and its catalog is used in residential, light commercial, and industrial heating systems. 3G Electric supplies White-Rodgers controls as individual replacement parts and as part of broader burner and gas-train assemblies. The line covers several functional categories: universal ignition gas valves, fan-control relays, surface-mounted relays, hot surface ignitors, limits, and thermostats. The universal ignition gas valves are single-stage or dual-stage, straight-through designs with ratings from 140,000 BtuH to 300,000 BtuH, and they are compatible with direct spark, hot surface, or intermittent pilot ignition systems. These valves are used where a replacement gas valve must match an existing manifold and control sequence without changing the appliance's ignition method. The relay line includes fan-control relays with SPDT contact forms and 120V AC coils, as well as surface-mounted magnetic relays with DPDT contacts rated for 15 A at 277V AC resistive load and 115/120V AC coils. These relays are used in fan circuits, blower controls, and other switching functions in HVAC and industrial equipment. Many White-Rodgers controls carry CSA, CUR, CUS, or UR recognition, and the parts are built to standard mounting and terminal configurations so they can be installed in existing equipment. 3G Electric stocks more than 140 White-Rodgers SKUs, including the 36H32, 36G22, 36H33, and 36H64 gas valve families, the 90 372S1 fan-control relay, and the 4E944 surface-mounted relay. For plant engineers and maintenance managers, this means access to replacement controls with published electrical and gas-flow ratings, so a substitute can be selected against the original specification. 3G Electric supports the line by providing part-level data, cross-referencing assistance, and global shipping from its Singapore headquarters. The company serves procurement specialists who need to source controls for scheduled maintenance, emergency repairs, or inventory stocking. Because White-Rodgers parts are used across many equipment brands, 3G Electric's catalog is organized by function and rating rather than by original equipment manufacturer, which simplifies the search for a compatible replacement. Technical buyers can review contact forms, coil voltages, BtuH ratings, and stage counts before ordering, and 3G Electric can supply the associated ignition modules, ignitors, and sensors that complete a gas-train or fan-control repair. The product range is intended for direct replacement in the field, not for redesign, so dimensions and terminal layouts follow common industry practice. For applications that require a specific ignition sequence or gas pressure regulation, the universal ignition gas valves provide a single component that can be configured for direct spark, hot surface, or intermittent pilot operation. This flexibility reduces the number of part numbers a maintenance department needs to stock while still covering a range of input capacities. 3G Electric's role is to make these parts available with clear specifications and without regional restrictions, so buyers can source White-Rodgers controls for equipment in any location.

Frequently asked questions

Common questions about WHITE-RODGERS from 3G Electric.

What is the difference between the White-Rodgers 36H32 and 36H64 universal ignition gas valves?

The 36H32 family includes single-stage, straight-through universal ignition gas valves, such as the 36H32-304 rated at 230,000 BtuH and the 36H32-423 rated at 300,000 BtuH. The 36H64 family includes dual-stage models, such as the 36H64-463 rated at 300,000 BtuH. Single-stage valves open to a fixed flow rate, while dual-stage valves provide two flow rates for staged combustion control. Both families are compatible with direct spark, hot surface, or intermittent pilot ignition systems and are used as replacements in residential, commercial, and industrial heating equipment. Selection depends on the required input capacity and whether the appliance controls firing in stages.

What are the electrical ratings for the White-Rodgers 4E944 surface-mounted relay?

The White-Rodgers 4E944 is a surface-mounted magnetic relay with double-pole double-throw (DPDT) contacts. It is rated for 15 A at 277V AC resistive load. The coil operates at 115/120V AC with a current draw of 66 mA. It uses a universal mounting style and quick-connect terminals. This relay is used in HVAC and industrial equipment for switching loads that require DPDT contact configuration, such as fan motors, compressors, or other circuits where two separate poles must be controlled simultaneously. The 15 A contact rating at 277V AC makes it suitable for many line-voltage control applications.

Can White-Rodgers universal ignition gas valves be used with direct spark and hot surface ignition?

Yes. White-Rodgers universal ignition gas valves are designed for use with direct spark, hot surface, or intermittent pilot ignition systems. This means the same valve family can be applied across different ignition methods, which is useful when replacing a valve on an appliance whose original ignition type may vary. The valve itself controls gas flow; the ignition source is managed by the associated ignition control module. When selecting a replacement, match the BtuH rating, stage count, and physical dimensions to the original valve. The universal design reduces the number of part numbers required to cover multiple ignition systems.

What is the contact form and coil voltage of the White-Rodgers 90 372S1 fan-control relay?

The White-Rodgers 90 372S1 is a fan-control relay with a single-pole double-throw (SPDT) contact form. It has both normally closed and normally open contacts. The coil operates at 120V AC, 50/60 Hz. It is used in HVAC systems and industrial equipment to control fan operation. The SPDT configuration allows the relay to switch between two circuits, which is common in fan control applications where the fan must run at different speeds or be turned on and off based on a control signal. The relay carries CSA, CUR, CUS, and UR recognition.

What BtuH ratings are available in the White-Rodgers 36G22 and 36H33 gas valve families?

The White-Rodgers 36G22-254 is a single-stage universal ignition gas valve rated at 140,000 BtuH. The 36H33-412 is a single-stage universal ignition gas valve rated at 300,000 BtuH. Both are straight-through designs for direct spark, hot surface, or intermittent pilot systems. The 36G22 family is typically used in residential and light commercial applications, while the 36H33 family is used in commercial and industrial heating applications requiring higher input capacities. When replacing a valve, confirm the BtuH rating matches the appliance's input and that the valve's pressure regulation and outlet size are compatible with the existing gas train.

How does 3G Electric support White-Rodgers product selection for industrial burners?

3G Electric stocks more than 140 White-Rodgers SKUs, including universal ignition gas valves, fan-control relays, surface-mounted relays, hot surface ignitors, and limits. For industrial burner applications, 3G Electric provides part-level specifications such as BtuH ratings, contact forms, coil voltages, and stage counts. Technical buyers can use these specifications to cross-reference an existing control or select a replacement. 3G Electric ships globally from Singapore and can supply associated ignition modules and sensors. The catalog is organized by function and rating, which helps maintenance managers identify compatible parts without relying on original equipment manufacturer part numbers.
