Liftmaster K94-38062-1, POWER BOARD ID RESISTOR, 1/2HP, 3PH
The LiftMaster K94-38062-1 is a power board ID resistor for select 1/2 HP, three-phase LiftMaster commercial slide gate operator configurations. The ID resistor is used by the operator control system to identify the power board or electrical configuration so the system can operate within the proper setup parameters.
This part is small, but the selection is important. LiftMaster uses different K94-38062 suffixes for different horsepower, voltage, and phase combinations. K94-38062-1 should be kept with 1/2 HP, three-phase applications and should not be swapped with the 1 HP K94-38062-2, 2 HP K94-38062-3, single-phase versions, or 575V-specific versions unless the manufacturer documentation specifically supports the change.
Compatible With
- Select LiftMaster SL585U slide gate operators with 1/2 HP three-phase configuration
- Select LiftMaster SL595U slide gate operators with 1/2 HP three-phase configuration where supported by diagram
- SL585UL / SL595UL style configurations only when the parts diagram lists K94-38062-1
- Not for 1 HP, 2 HP, single-phase, or 575V-specific ID resistor applications
- Not a replacement for K94-38062-2, K94-38062-3, K94-38062-4, K94-38062-5, or K94-38062-6 unless documented

Technician Note
Treat the ID resistor as a configuration part. If the wrong resistor is installed, the control system may not identify the operator setup correctly, and troubleshooting can become misleading.
Before Ordering
- Confirm the operator model is SL585U, SL595U, or a documented matching variant.
- Verify the operator is 1/2 HP.
- Verify the operator is three-phase.
- Check whether the system requires a standard 3PH or 575V-specific resistor.
- Compare the old resistor part number and power board diagram.
Professional Advisory
Power board and ID resistor work should be handled with power disconnected. For three-phase commercial equipment, use a qualified technician or electrician.
Important Ordering Warnings
- Do not use this on 1 HP or 2 HP operators.
- Do not use this on single-phase operators.
- Do not assume all K94-38062 resistors are interchangeable.
- Incorrect horsepower or phase identification can create control and service issues.
Product Questions and Answers
What does K94-38062-1 identify?
It is used as a power board ID resistor for 1/2 HP, three-phase LiftMaster commercial slide gate operator configurations.
Which operator families commonly use this resistor family?
The K94-38062 ID resistor family is commonly associated with SL585U and SL595U slide gate operator platforms, but the exact suffix must match the operator configuration.
Can K94-38062-1 replace K94-38062-2?
No. K94-38062-2 is the 1 HP three-phase version. K94-38062-1 is for 1/2 HP three-phase configurations.
Why are horsepower and phase important?
The ID resistor tells the operator control system which electrical configuration is installed. A mismatch can cause incorrect recognition or troubleshooting problems.
Should this be replaced during power board service?
It should be checked and replaced only when the parts diagram or diagnosis calls for it, and the replacement must match the exact operator electrical configuration.
