Before you buy — quick checklist

Confirm your control pack uses a 15 VDC coil relay — coil voltage must match exactly
Verify the failed relay on your board is a T91-style footprint before ordering
Check that your circuit load does not exceed the 30A switching rating
Inspect the PCB relay socket or solder pads for burn damage before replacing the relay alone
Confirm SPST-NO configuration matches your board's switching logic
