Product Overview
An incorrect temperature reading, warning circuit that never comes on, or a warning that stays active even when the engine is cold can point to the coolant temperature switch or its wiring on MTD, Bolens and Troy-Bilt equipment using water-temperature switch MM432-104 / 1850218.
Inspect the connector and verify the cooling system is actually operating at the correct temperature first. A failed switch can send the wrong signal even when the engine itself is cooling normally.
