Good To Know
Q: What does the AM100856 part number mean? A: AM100856 is the original John Deere reference number for this switch. This replacement part is designed to match the same specifications and function as that original component.
Q: How do I know if my switch needs replacing? A: If the oil pressure warning light does not come on when the key is turned to the on position, or if it stays on after starting with proper oil levels, the switch may be faulty. Replacing it restores accurate oil pressure monitoring.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
