Product Description
The Ruud 42-23116-07K sequencing relay operates at 24V with a three-pole, single-throw (3PST) normally open configuration. This relay is crucial for monitoring the heat around the burners in HVAC systems. It stops the ignition sequence if the inducer fan fails to draw enough air or if there are issues with furnace venting. This function helps to avoid potential heating problems in furnaces.
- 24V operational voltage
- Prevents furnace overheating by monitoring air flow
- Replaces part number 42-23116-07
Product Highlights
This relay is designed for automatic operation and ensures safety in heating systems.
Product Information
Standard Information
- Brand: Ruud
- Condition: New
Features:
- 50/60 cycle
- UL and CSA approved
- Contact rating 35 amp, 480 VAC
- Non-positional
- Instructions and wiring diagram included in each relay
Compatibility & Applications:
- Intended for use in air conditioners, heat pumps, and other HVAC equipment requiring a 2-pole, 40 amp, 24V coil contactor
- Suitable for residential and light commercial outdoor units, air handlers, and other equipment within the contactor's ratings
- Used as a replacement where equipment specifications call for a 2-pole contactor with similar electrical ratings and coil voltage
Installation & Operation Notes:
- Disconnect power at all sources and verify that all circuits are de-energized before starting work
- Mount the contactor securely in the control compartment or electrical panel as directed by the equipment manufacturer
- Move line, load, and control wires from the existing contactor to the new contactor, matching wiring diagrams and terminal markings
- After energizing the system, verify that the contactor pulls in and opens cleanly, with proper operation during system start and stop cycles
- Confirm that all terminations are tight and that wiring is supported to prevent strain at the terminals
Maintenance & Troubleshooting:
- Inspect the contactor during routine HVAC maintenance for pitted or burned contacts, coil discoloration, or mechanical binding
- Replace the contactor if the coil fails to energize, if the contacts do not close fully, or if there is evidence of overheating or excessive humming
- If repeated contactor issues occur, verify that load current and control voltage are within specification and that short cycling is not overstressing the contactor
Certifications & Compliance:
- Meets ARI 780/790 Standard
