This is a replacement flame sensor designed for both the 45H Outdoor and 45HI Indoor units. This sensor plays a vital role in detecting the crucial flame ignition process, ensuring seamless operation.

The 45H/HI Flame Sensor is an essential component in your tankless water heater, serving a critical role in monitoring the flame. Its primary function is to detect the presence of the burner flame, ensuring safe and efficient operation. So, how can you tell if it's time to replace the 45H/HI Flame Sensor?

Here are some signs to watch out for:

Flame Detection Issues: If your tankless water heater struggles to detect or maintain a flame consistently, it might indicate a problem with the sensor. This can manifest as repeated ignition attempts or the heater shutting down due to the absence of a detected flame.

Error Codes or Warning Lights: Some tankless water heaters display error codes or use indicator lights to signal sensor malfunctions. An E6, or an E0 code could be given off. Keep an eye out for any error messages or warning lights related to flame detection issues.

Visual Inspection: Over time, the sensor may accumulate dirt or corrosion, hindering its ability to detect the flame. Visually inspect the sensor for any signs of damage, debris, or corrosion that could impact its performance.

Age and Usage: Similar to most components, the flame sensor can wear out over time due to prolonged use. If your water heater has been in service for an extended period and you're experiencing flame detection problems, it might be time for a replacement.

When it comes to replacing the 45H/HI Flame Sensor, it's crucial to follow the manufacturer's recommendations outlined in your heater's user manual.
