Frequently asked questions
Common questions about FENWAL IGNITION CONTROLS from 3G Electric.
What voltage options are available for Fenwal ignition control boards from 3G Electric?
Fenwal ignition control boards stocked by 3G Electric are available in 24V AC and 120V AC configurations. For example, part numbers 35-605928-215, 35-655700-003, 35-665725-121, and 35-615922-125 are 24V models, while 35-705600-005 is a 120V model. Always verify the voltage rating of your existing control before ordering to ensure compatibility with the system's transformer and gas valve.
Are Fenwal ignition control boards interchangeable with other brands?
Fenwal ignition control boards are designed to specific electrical and mechanical specifications, including mounting hole patterns, connector types, and timing sequences. While some boards may have similar functions, direct interchangeability with other brands is not guaranteed. It is recommended to replace with the exact Fenwal part number or a manufacturer-approved cross-reference. 3G Electric lists the manufacturer part number for each SKU to facilitate accurate matching.
What is the typical application for Fenwal ignition control boards?
Fenwal ignition control boards are used in gas-fired heating equipment such as furnaces, boilers, unit heaters, rooftop units, and commercial cooking appliances. They manage the ignition sequence, flame sensing, and safety lockout functions. The boards are commonly found in HVACR systems requiring direct spark or intermittent pilot ignition, and are suitable for both new installations and replacement in existing equipment.
How do I identify the correct Fenwal ignition control board for my system?
To identify the correct Fenwal ignition control board, check the part number on the existing board, which is typically printed on a label or etched into the circuit board. Cross-reference this with the manufacturer part numbers listed in 3G Electric's catalog, such as 35-605928-215 or 35-755900-009. Also note the voltage rating (24V or 120V) and the type of ignition system (DSI or IP). If the part number is unreadable, consult the equipment's service manual.
Do Fenwal ignition control boards include diagnostic features?
Many Fenwal ignition control boards include diagnostic LED indicators that flash error codes to indicate fault conditions such as flame failure, ignition lockout, or sensor issues. For example, some models have a single LED that blinks a specific number of times to correspond with a fault code. Refer to the board's datasheet or the equipment's troubleshooting guide for code interpretation. 3G Electric's product listings may include specifications, but diagnostic details are typically found in the manufacturer's documentation.
Can I order Fenwal ignition control boards from 3G Electric for international shipment?
Yes, 3G Electric ships Fenwal ignition control boards globally. The company provides logistics support for international orders, including documentation for customs clearance. When ordering, specify the part number and quantity, and 3G Electric can arrange shipping to your location. Lead times may vary based on stock availability and destination.
