Genuine Cummins Onan PCB control assembly for compatible RV QG, Camp Power, and MicroLite/MicroQuiet KY and KYD generator applications.
The Cummins Onan 327-1413 is a generator circuit control board used on select Onan RV generator models. The control board helps manage generator starting, running, and control functions, making it an important component when diagnosing generator start/stop or control-related issues.
This board is commonly listed for RV QG, Camp Power, and MicroLite/MicroQuiet generator models in the KY and KYD families. Because Onan control boards are model- and spec-specific, always verify the generator model number, spec letter, and existing board part number before ordering.
Replacement circuit control board for compatible Onan RV generator applications
OEM Cummins Onan replacement component for supported generator models
Commonly listed for RV QG, Camp Power, and MicroLite/MicroQuiet KY and KYD models
Generator model, spec letter, and original board number should be confirmed
This control board is not universal for all Onan generators. It is commonly listed for KY and KYD model families, but compatibility can vary by generator model, spec letter, wiring configuration, and board revision. Before ordering, compare the original board part number and confirm the generator model/spec from the generator nameplate. Do not order by appearance alone, as several Onan control boards can look similar but operate differently.
Before Starting: Shut down the generator, disconnect applicable power sources, and follow all Cummins Onan generator service precautions. Electronic control board replacement should be performed by qualified personnel familiar with RV generator electrical systems. Basic Replacement Steps: 1. Confirm Compatibility: Verify generator model, spec letter, serial number, and original control board part number. 2. Disconnect Power: Make sure the generator cannot start and that battery/starting power is safely disconnected before service. 3. Access Control Area: Remove the required generator access cover or control panel cover to reach the board assembly. 4. Document Wiring: Take clear photos of all wire positions and connectors before disconnecting the original board. 5. Remove Old Board: Carefully disconnect harnesses and remove the failed or damaged PCB assembly. 6. Install Replacement Board: Mount the replacement board and reconnect wiring exactly as required for the generator model. 7. Inspect Related Components: Check switches, harnesses, connectors, fuses, brushes, slip rings, and charging/starting circuits as applicable. 8. Test Operation: Reassemble the control area, restore power, and verify proper generator start, stop, and run operation.
Package Contents: • Cummins Onan 327-1413 generator circuit control board / PCB assembly NOT Included — May Also Need: • Generator wiring harness • Start/stop rocker switch • Interior remote panel • Voltage regulator or other control modules • Generator control panel enclosure • Fuses, terminals, or connectors This listing is for the control board only. Inspect the generator wiring and related control components before replacing the board.
To confirm compatibility before ordering, have the following ready: • Generator model number • Spec letter • Serial number • Existing board part number, if visible • Whether the generator is KY or KYD series • Description of the generator symptom being diagnosed Why this matters: Onan generator control boards are tied to the generator model/spec and control configuration. Matching only the board appearance may result in the wrong replacement part.
Match this control board by generator model, spec letter, and original board number. Control boards should not be selected by appearance alone.
Control board replacement should be based on proper diagnosis. Generator no-start or shutdown issues can also be caused by fuel, ignition, wiring, battery, brush, slip ring, or rotor/stator problems.
