Laars Heating Systems RE2370700 Transformer

Laars Heating Systems RE2370700 Transformer

If you are troubleshooting a Laars boiler and find your 24V control circuit is dropping out under load, the Laars Heating Systems RE2370700 Transformer is the direct performance replacement you need. This 75VA control transformer is a significant upgrade over standard 40VA units, providing the necessary amperage to drive multiple zone valves, heavy-duty 24V contactors, and modern smart thermostats without overheating. Featuring a 120V primary and 24V secondary, it is engineered for the high-demand environments of commercial and residential hydronic systems. This HVAC step-down transformer ensures stable voltage regulation for flame safe-guards and ignition modules in NeoTherm and other high-efficiency Laars units. As a seasoned tech, you know that undersized iron leads to chatter and premature component failure; this 75VA HVAC transformer eliminates those callbacks. Its robust footprint and lead-wire configuration allow for a seamless fit into existing control cabinets, maintaining Class 2 transformer safety compliance while improving overall system reliability.

Key Benefits
  • High Power Capacity: The 75VA rating supports larger control loads, preventing voltage sagging during simultaneous component activation.
  • Precise Voltage Conversion: Converts 120V primary line voltage to a steady 24V secondary output for sensitive electronic boards and sensors.
  • OEM Compatibility: Specifically designed as an authentic Laars RE2370700 replacement part for guaranteed fitment in NeoTherm series and related models.
  • Enhanced Thermal Stability: Built to withstand the high ambient temperatures found within boiler cabinets without compromising power delivery.
  • Class 2 Rated: Meets rigorous safety standards for low-voltage residential and commercial heating control circuits.
Common Questions

Can I use this 75VA transformer to replace a 40VA unit?
Yes. In the field, upgrading to a higher VA rating is a standard practice to solve issues with "tripping" or humming. As long as the primary and secondary voltages match (120V/24V), the 75VA capacity provides more "muscle" for the system without harming components.

Why is my transformer buzzing or getting excessively hot?
Loud buzzing or high surface temperatures usually indicate an overload on the 24V side. If you have added multiple zone pumps or smart accessories, the cumulative draw may exceed your current transformer's limits. Stepping up to this 75VA transformer often resolves these mechanical vibrations.

How do I verify if the RE2370700 is the correct part for my Laars model?
Check your unit's wiring diagram or parts list for part number RE2370700 or NT 80-850. This transformer is widely utilized in the NeoTherm and Mascot series where 75VA of control power is required for the ignition sequence and peripheral controls.
