Common Questions about the 20162907SP

What causes a primary limit switch to trip repeatedly?
Common causes include a dirty air filter, a failing blower motor, or blocked return air ducts, all of which restrict airflow across the heat exchanger.

Is the 20162907SP compatible with older 20162907 models?
Yes, the 20162907SP is the official service replacement part and is fully compatible with all units previously utilizing the 20162907 switch.

Can I use a higher temperature limit switch if this one keeps tripping?
No. You must always use the manufacturer-specified temperature rating (155°F) to ensure the safety of the heat exchanger and the property.
