The sensor harness on a Rinnai HDC1600i carries the temperature readings from the appliance's sensors back to the main control board. Accurate signal transmission here is essential — the appliance can only regulate combustion and temperature as well as the data it's receiving.
Wiring harnesses are a wear item: repeated heat cycling and general use can degrade connections over time, leading to signal loss or intermittent readings. This genuine Rinnai harness, made to the original specification for the HDC1600i, restores a clean connection between the sensors and the control board, keeping combustion and temperature control accurate.
⚠ Important: Installation and servicing must be carried out by a qualified technician familiar with Rinnai products. Turn off the gas supply and disconnect power before beginning any servicing.

Why Buy This Product?
Erratic temperature control or intermittent sensor faults on a HDC1600i often come down to wiring rather than the sensors themselves, especially once a harness has been through repeated heat cycles. This genuine part restores that connection to factory reliability, so the control board is working from accurate data rather than a degraded signal.
