Description
Rheem-Ruud 470029 Limit Switch Overview
The Rheem-Ruud 470029 is a factory-specified limit switch engineered to protect furnaces and heating equipment from dangerous overheating conditions. Designed as a direct OEM replacement for compatible Rheem and Ruud heating systems, this limit switch delivers dependable thermal protection and helps maintain safe, efficient operation.
How It Works
The limit switch continuously monitors heat exchanger or plenum temperatures. When the sensed temperature reaches the open setpoint, the switch interrupts the burner circuit to prevent equipment damage or fire hazard. Once temperatures fall back to the reset threshold, the switch closes and restores normal operation.
