Westinghouse 626432R Fan Limit Switch 145-165F Auto Reset

Product Description

The WESTINGHOUSE 626432R is an auto-reset fan limit switch rated for air conditioner applications. It operates across a temperature range of 145 to 165 degrees F and uses a 3-inch insert to mount into the equipment. The switch controls fan operation by opening and closing circuits based on sensed temperature, protecting the system from operating outside safe thermal limits. Licensed HVAC technicians typically source this switch as a direct service replacement during seasonal maintenance or component failure diagnosis.

This fan limit switch is designed for use on air conditioning equipment where temperature-actuated fan control is required. The auto-reset function means the switch returns to its normal operating position once temperatures fall back within the rated range, eliminating the need for manual reset after a thermal event. The 3-inch insert format is a common configuration found in residential and light commercial air conditioner installations.
