Genie 38878R.S Configurable Circuit Board with Wall Console
The Genie 38878R.S is a genuine-style configurable control board and wall console kit used to replace multiple older Genie DC opener circuit boards. It is not just a simple plug-in board for one model; it is supplied as a non-configured replacement board that must be set up for the correct model family, often by following the included configuration/resistor instructions. This matters because Genie used related board platforms across screw drive, chain drive, and belt drive operators, but the R1, R2, R3, and R4 variations are tied to different motor and encoder configurations. When the original board fails, the opener may lose travel memory, stop responding to wall controls, fail to power accessories, run erratically, or refuse to complete a learn cycle. This kit is most useful when the old part number has been superseded and the service technician needs one replacement platform that can be configured to match the opener.

Technician Note
Match the original board number and model family before replacing the board. A 38878R.S installed with the wrong configuration can create travel, motor, wall console, or accessory issues even though the connector layout appears similar.
Before Ordering Checklist
- Confirm the opener model number from the powerhead label
- Record the original circuit board number before removal
- Verify whether the opener uses a Series II wall console or requires the included console
- Review the configuration/resistor instructions included with the replacement board
- Plan to reset travel limits and reprogram remotes, keypads, and accessories after installation
Professional Advisory
Disconnect power before servicing the opener. If the opener has burned components, damaged wiring, intermittent motor operation, or unsafe door movement, have a qualified garage door technician inspect the system before replacing the board.
Product Questions
Why does the 38878R.S need to be configured?
The 38878R.S is supplied as a replacement platform for several Genie board families. It must be configured for the correct model series so the board matches the motor, encoder, and control layout of the opener.
Does this replace Genie 38514R.S?
It is commonly used as the replacement path for 38514R.S when the opener model and configuration match. Always verify the original board and opener model before ordering.
Does the kit include a wall console?
Yes. The 38878R.S kit is commonly supplied with a Series II wall console, which may be required when replacing certain older boards.
Will my remotes still work after changing the board?
Compatible remotes and keypads usually need to be reprogrammed after the board is installed and the travel limits are reset.
Is this board for every Genie opener?
No. It is for select Genie DC opener families only. It should not be used on unrelated AC screw drive, older fixed-code, or commercial operator boards unless the parts diagram confirms compatibility.
