Product Description

The LOCHINVAR L100284345 is a main control board rated for 150 MBH heating capacity, designed to serve as the central processing and sequencing component in a LOCHINVAR heating appliance. The control board manages ignition sequencing, burner operation, safety lockout logic, and system fault monitoring. It is the primary electronic assembly that coordinates inputs from sensors, thermostats, and safety switches to maintain proper combustion and heating operation. This board is a direct OEM-style replacement component, typically installed by licensed HVAC technicians or qualified heating contractors during scheduled maintenance or component failure service calls.

This main control board is intended for use in LOCHINVAR heating equipment rated at 150 MBH output.
