Description
The Modine 5H0750310000 is a genuine OEM replacement flame sensor designed for use in Modine heating systems. Flame sensors play a critical role in the safe operation of gas-fired heating equipment — they detect the presence of a burner flame and send a signal to the control board to confirm ignition. If no flame is detected, the control system will shut off the gas valve, preventing dangerous unburned gas accumulation.
Replacing a worn or faulty flame sensor is one of the most common service procedures for maintaining reliable heater performance. A degraded sensor can cause nuisance lockouts, failed ignition sequences, and reduced heating efficiency. Using a genuine Modine OEM part ensures proper fit and function, maintaining the integrity of your heating system.

Why Replace Your Flame Sensor?
Over time, flame sensors can develop a coating of oxidation or residue that reduces their ability to conduct the small microamp current used to confirm flame presence. This leads to repeated ignition failures and system lockouts. Replacing the sensor with a genuine Modine part restores reliable operation and extends the service life of your heating equipment.
