The LiftMaster K25-2006 is a 6 amp overload switch used as a protective electrical component in select LiftMaster commercial door and gate operator assemblies. It is commonly found in the electrical box or control area where the operator parts list calls for a 6A overload. The purpose of the overload is to help protect the circuit when current demand exceeds the intended rating for that part of the operator system.
This part should be matched by rating and part number, not by appearance alone. LiftMaster uses multiple overload ratings across commercial operators, and a 6A overload is not the same as a 10A overload or other protective devices used in different electrical boxes. If the overload has been tripping repeatedly, the root cause may be a failing motor, brake issue, binding door or gate, incorrect voltage, wiring problem, or damaged control component.

Repeated overload trips should not be treated as a bad overload automatically. Check for mechanical drag, wrong input power, motor problems, brake problems, shorted wiring, or a failing control component before returning the operator to service.
Commercial door and gate operators can contain high-voltage wiring and moving parts. Disconnect power and follow lockout procedures before service. If the overload trips again after replacement, the operator should be diagnosed before continued use.
K25-2006 is a 6 amp overload switch.
It is listed for various LiftMaster commercial door operator electrical boxes and commercial gate operators where the parts diagram calls for this 6A overload.
No. K25-2006 is the 6A overload, while K25-2010 is commonly listed as a 10A overload. They should not be swapped unless the correct parts diagram specifically allows it.
Related numbers include G252006 and 25-2006.
Repeated tripping may point to a motor, brake, wiring, voltage, binding door, or gate load issue. A technician should diagnose the cause before the operator is placed back in service.
