What this limit switch does

The Goodman 1370905S is a 3-inch limit switch designed for RV heating, ventilation and air-conditioning systems. It opens the safety circuit when the sensed temperature reaches the upper end of its range. The component is supplied new and intended as a direct replacement for the original equipment part.

Temperature range and response

The switch operates between 260 and 290 degrees Fahrenheit with a 30-degree differential. This means the contacts will open near the top of that band and will not reset until the temperature has fallen by roughly 30 degrees. The fixed range cannot be adjusted in the field.

Verify fitment before ordering

Confirm that your furnace or air-handler calls for a 3-inch insertion length and the L290-30F temperature rating. Cross-reference the 1370905S part number against the manufacturer’s service literature for your specific model. Installation should be performed by a qualified HVAC technician.
