Westinghouse 626599R Limit Switch 160V Package Unit

Product Description

The WESTINGHOUSE 626599R is a limit switch rated at 160 volts, designed for use in gas heating and electric cooling package units. A limit switch in this application monitors temperature conditions within the unit and interrupts the circuit when a preset threshold is reached, protecting the system from overheating or unsafe operating conditions. This part is a direct-replacement component typically installed by licensed HVAC technicians during preventive maintenance or service calls involving overtemperature faults or limit control failures.

This limit switch is specified for use on R8HE Gas Heating and Electric Cooling Package Units. Package units of this type are self-contained systems commonly installed in light commercial and residential applications, mounted on rooftops or at grade level. When a limit switch fails or trips repeatedly, replacement is the standard corrective action after ruling out airflow restrictions, dirty filters, or blocked heat exchangers.

Key Features

• Rated at 160 volts for compatibility with R8HE package unit control circuits
• Functions as an overtemperature safety device to protect the heat exchanger and surrounding components
• OEM-style replacement designed to restore proper limit control operation
• Direct fit for R8HE Gas Heating and Electric Cooling Package Units

Compatibility

Specified for use on the R8HE Gas Heating and Electric Cooling Package Unit series.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect all power to the unit at the disconnect switch or breaker before removing or installing any limit switch. Verify the new switch matches the original mounting configuration and voltage rating before energizing the system. After installation, cycle the unit and confirm normal limit control operation before returning the equipment to service.
