The Packard PRL130 is a manual reset fan and limit switch engineered to provide dependable overheat protection and precise fan sequencing in forced-air heating systems. Designed as a direct replacement or upgrade component, this switch monitors furnace plenum temperatures and automatically shuts down the burner circuit when unsafe high-limit temperatures are detected — requiring a manual reset before the system can resume operation, adding an extra layer of safety against recurring overheat conditions.
Key Features
- Manual reset design requires technician intervention after a high-limit trip, preventing automatic restart under unsafe conditions
- Dual-function control manages both fan ON/OFF sequencing and high-limit burner shutoff in a single device
- Replaces worn or failed OEM fan and limit switches in a wide range of forced-air furnace applications
- Compact, robust construction built for long-term reliability in demanding HVAC environments
- Easy field installation with standard mounting configuration
Application
The PRL130 is ideal for residential and light commercial forced-air furnaces where a manual reset high-limit function is required. It sequences the blower fan to turn on once the heat exchanger reaches operating temperature and shuts the fan off after the burner cycle ends — while simultaneously protecting against dangerous overheating conditions.
Why Choose the Packard PRL130?
Packard has been a trusted name in HVAC replacement controls and components for decades. The PRL130 delivers the reliability and compatibility professionals expect, making it a go-to solution for service technicians and HVAC contractors handling furnace limit switch replacements.
