York 031-02060-003 Board
The York 031-02060-003 SCR Trigger Board is a York OEM control board that produces the gate firing pulses for silicon controlled rectifiers (SCRs). An SCR conducts only when its gate receives a pulse, so the trigger board is the component that decides exactly when the power devices turn on in each cycle. When the firing signals are late, missing or uneven, power conversion becomes unstable, and the equipment it serves can fail to start, fault out or trip repeatedly. The 031-02060-003 is the third number in York's 031-02060 board family, which also includes the 031-02060-001 and the 031-02060-002.
The dash number matters on this board. The 031-02060-003 is not the same part number as the 031-02060-001 or 031-02060-002, and York also uses a different board, the 031-01472-000, in its variable speed drive equipment, so SCR trigger boards cannot be substituted by name or description. Read the complete part number printed on the board you are replacing and match it character for character. If your board reads 031-02060-003, this is the OEM replacement. If it reads -001 or -002, order that exact number instead. Our team can help you confirm the match if you send the equipment model and serial number.
Treat any SCR-based power equipment repair as high-energy work. Before replacing a trigger board, 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 left in the circuit can damage a new trigger board the moment power is applied. 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 you unplug anything so the new 031-02060-003 goes back exactly as the original was wired. This is work for a qualified technician who knows York SCR power equipment.
Key Benefits
- York OEM board: The factory York 031-02060-003, not a generic gate-drive substitute built to a different specification.
- 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 is missing.
- Clearly separated from its siblings: Distinct from the 031-02060-001, 031-02060-002 and 031-01472-000, so you can order by the exact number on your board.
- Built for technician-level repair: A complete board, ready to install once the SCRs, fuses and connectors have been checked.
Common Questions
What does the York 031-02060-003 do?
It is an SCR trigger board. It sends the gate firing pulses that switch the SCR power devices on at the correct point in each cycle.
Is it the same as the 031-02060-001 or 031-02060-002?
No. 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.
