SOURCE1 2435738000 Furnace Door Push Button Switch

Product Description

The SOURCE1 2435738000 is a furnace door push button switch designed for use in residential and light commercial HVAC systems. This OEM replacement part meets the original manufacturer specifications, making it a reliable choice for HVAC technicians and service professionals who need a direct-fit replacement. The switch mounts to the furnace door panel and controls power or a specific function by interrupting or completing the circuit when the door is opened or closed. This safety interlock mechanism is a critical component in modern gas and electric furnaces, preventing the unit from operating when the access panel is removed. Without a properly functioning door switch, the furnace will not fire or run, which is a common service call issue for HVAC technicians in the field.

It is a direct replacement for units including the 1NP0810, 1NP0806, and 1SP0452 models, among others. The compact form factor makes installation straightforward, requiring no modification to the existing door frame or wiring. HVAC service professionals rely on this type of push button interlock switch to restore safe and proper furnace operation quickly. Keeping this part on a service truck or in a parts inventory reduces downtime on furnace repair calls. The switch is lightweight at 0.025 pounds and measures 4.2 inches in length, 3.5 inches in width, and 1.1 inches in height, fitting neatly within the furnace door assembly.
