Description
The Rinnai 805000035 is a genuine OEM NTC (Negative Temperature Coefficient) temperature sensor designed to monitor T1 and T3 water temperatures in Rinnai tankless water heaters. This precision sensor plays a critical role in the unit’s control system, continuously feeding accurate temperature data to the heater’s control board to maintain consistent, safe, and efficient hot water delivery.
Product Overview
NTC thermistors like the Rinnai 805000035 change electrical resistance in response to temperature fluctuations, allowing the water heater’s control board to make real-time adjustments to burner output and flow. Replacing a faulty T1 or T3 sensor with a genuine Rinnai OEM part ensures the unit operates within designed parameters and helps prevent error codes, temperature instability, and potential overheat conditions.
Key Features
- Genuine Rinnai OEM replacement part — ensures compatibility and reliable performance
- NTC (Negative Temperature Coefficient) thermistor technology for accurate, responsive temperature sensing
- Monitors T1 (inlet water temperature) and T3 temperature sensing points
- Designed for use in Rinnai tankless water heater systems
- Helps prevent error codes associated with temperature sensor faults
- Direct drop-in replacement for straightforward servicing
Application
This sensor is a direct replacement part for Rinnai tankless water heaters requiring T1 or T3 temperature sensor service. It is intended for use by qualified HVAC and plumbing technicians performing diagnostics and repairs on Rinnai tankless units.
Why Choose Genuine Rinnai OEM Parts?
Using genuine Rinnai OEM components ensures your repair meets the manufacturer’s original specifications, preserves warranty coverage where applicable, and delivers the long-term reliability your customers expect. Aftermarket sensors may not match the resistance curve or connector configuration of the original part, leading to inaccurate temperature readings or continued fault codes.
