Laars Heating Systems E2328000 Relay

The Laars E2328000 Relay is a mission-critical DPDT switching relay designed for demanding hydronic and steam boiler control circuits. Engineered for 120V AC input, this Double Pole Double Throw component provides reliable isolation and simultaneous control of multiple high-load circuits, such as circulating pumps, blowers, or localized zone valves. In the field, this relay is frequently utilized within Laars heating systems to interface low-voltage thermostats with line-voltage equipment, ensuring precise sequencing and system protection. Its heavy-duty contact design minimizes arcing and extends service life under high-cycle conditions, making it a standard replacement part for maintaining HVAC system reliability and peak thermal efficiency. When diagnosing boiler control failures, verifying the coil resistance and contact continuity of the E2328000 relay is essential for restoring the 120-volt switching logic required for safe appliance operation.

• Universal 120V Compatibility: Matches standard line-voltage control requirements for Laars and compatible boiler platforms.
• DPDT Contact Configuration: Allows for complex switching of two separate circuits, ideal for simultaneous pump and burner management.
• Industrial-Grade Built: High-quality internal components ensure stable performance in high-ambient temperature environments near the heat exchanger.
• Direct OEM Replacement: Ensures precise fitment and electrical alignment, reducing installation time and eliminating the need for field modifications.

Common HVAC Technical Questions

What is the maximum amperage rating for the E2328000 relay contacts?
This 120v DPDT relay is typically rated for standard inductive loads found in domestic and light commercial boiler pumps; however, always verify the specific FLA and LRA ratings on the component casing to ensure compatibility with your motor load.

Can this relay replace a SPDT relay in a Laars unit?
Yes, a DPDT relay can serve as a substitute for a SPDT relay by utilizing only one set of contacts, provided the coil voltage and physical mounting footprint match the boiler wiring diagram.

How do I troubleshoot a suspected failure in this relay?
Check for 120V at the coil terminals. If power is present but the contacts do not switch, or if there is no continuity across the normally open (NO) terminals when energized, the relay must be replaced to restore hydronic system control.
