Specs At A Glance

Good To Know

Q: Will this switch fit any year of the Rancher 350? A: It is listed for 2000 through 2006 models that use these OEM numbers, so verify the part number on your machine first. Trim levels and production changes can affect fit, so matching the number is the safest check.

Q: What happens if the switch fails? A: A failed switch can leave the fan running constantly or not at all, and a fan that never engages leads to overheating. Replacing the switch is a straightforward fix once the fault is confirmed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
