York 031-02060-002 Board
The York 031-02060-002 SCR Trigger Board is a York OEM control board that supplies the timed gate firing pulses for silicon controlled rectifiers (SCRs). An SCR only conducts when it receives a gate pulse, so the trigger board is the part that decides when the power devices switch. If the firing signals are late, missing or uneven, power conversion becomes unstable, and equipment that depends on it can fail to start, fault out or trip repeatedly. The 031-02060-002 sits in York's SCR trigger board numbering alongside the 031-02060-001 and 031-02060-003.
Identify it by the complete part number. York also uses a different trigger board, the 031-01472-000, in its variable speed drive equipment, so SCR trigger boards are not interchangeable by description. The 031-02060 series is its own board family, so match the number printed on the board you are replacing and do not substitute by name. The factory photo shows a green circuit board with a yellow Microtran transformer marked for 115V input at 50/60Hz with 28V and 14V outputs, large aluminum electrolytic capacitors mounted with finned heat sinks, groups of brown power resistors, white multi-pin connector headers, three quick-connect terminal tabs (TB1, TB2 and TB3) and a barcode label.
Treat any SCR-based power equipment repair as high-energy work. Confirm the incoming three-phase voltage and fuses, check that every harness and ribbon connector is fully seated, and test the SCRs themselves, because a shorted SCR can damage a new trigger board. Inspect the old board for burned traces, discolored components, cracked solder joints and corroded connectors. Lock out and tag out the equipment, wait for the DC bus capacitors to discharge, verify zero volts with a meter, use anti-static precautions and photograph every connector before disconnecting so the new 031-02060-002 goes in exactly as the original was wired. This is work for a qualified technician familiar with York SCR power equipment.
Key Benefits
- York OEM board: The factory York 031-02060-002, not a generic gate-drive substitute.
- Restores gate firing: A healthy trigger board delivers clean, correctly timed SCR gate pulses, which is what equipment that will not start or keeps faulting on the SCR section needs.
- Clearly separated from its siblings: Distinct from the 031-02060-001, 031-02060-003 and 031-01472-000, so you can order by the exact number on your board.
- Ready for technician-level repair: Arrives as a complete board with the transformer, capacitors and connectors already assembled.
Common Questions
What does the York 031-02060-002 do?
It is an SCR trigger board. It sends the gate firing pulses that turn the SCR power devices on at the correct moment in each cycle.
Is it the same as the 031-02060-001 or 031-02060-003?
They are separate York part numbers in the same SCR trigger board family. Match the full number printed on the board you are replacing, and contact us with the equipment model and serial number if the numbers differ.
What should I check before installing a new trigger board?
Check the three-phase supply and fuses, the connector seating and the SCRs for shorts, and inspect the old board for burn marks. A shorted SCR left in place can damage the new board.
