Select it by the complete operator model, installed motor label and exact suffix. The horsepower and phase are only part of the selection: mounting, shaft, electrical connection and drive arrangement must match. It is a motor service item rather than a complete operator or a general power upgrade for an existing door system.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModels expressly listing K20-1100C-2LP-H28\u003c\/td\u003e\n\u003ctd\u003eMatch the complete model and motor suffix.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH101L5 \/ GSD101L5\u003c\/td\u003e\n\u003ctd\u003eDocumented examples; verify installed configuration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther horsepower ratings\u003c\/td\u003e\n\u003ctd\u003eNo automatic upgrade or substitution.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThree-phase motors\u003c\/td\u003e\n\u003ctd\u003eDifferent electrical requirements.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOlder unsuffixed motor references\u003c\/td\u003e\n\u003ctd\u003eConfirm the actual service relationship before ordering.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eMatch the Mounting and Motor Wiring Before Ordering\u003c\/h2\u003e\u003cp\u003eRecord the complete operator and motor nameplates before ordering, then compare the mounting points, shaft connection and wiring with the service drawing.

A drive that binds or a brake that does not release can resemble a motor fault. The replacement should restore the specified arrangement. Changing pulleys, bypassing protection or guessing a voltage connection is not an acceptable way to make an unsuitable motor operate.\u003c\/p\u003e\u003ch2\u003eSpecifications and Product Identification\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003eK20-1100C-2LP-H28\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHorsepower\u003c\/td\u003e\n\u003ctd\u003e1 HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase\u003c\/td\u003e\n\u003ctd\u003eSingle phase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl platform\u003c\/td\u003e\n\u003ctd\u003eDocumented Logic 5 configurations\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer examples\u003c\/td\u003e\n\u003ctd\u003eGH101L5 \/ GSD101L5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply and wiring\u003c\/td\u003e\n\u003ctd\u003eMatch operator and delivered motor diagram\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eBefore Ordering\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRecord full operator model and existing motor nameplate.\u003c\/li\u003e\n\u003cli\u003eConfirm 1 HP, single phase and exact K20-1100C-2LP-H28 suffix.\u003c\/li\u003e\n\u003cli\u003eMatch shaft, mounting and documented electrical connection.\u003c\/li\u003e\n\u003cli\u003eInspect the drive and door condition before selecting a motor-only repair.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis offer identifies the K20-1100C-2LP-H28 replacement motor.
