Ao Smith 100271886 Lower Temperature Probe

Product Description

The AO SMITH 100271886 is a lower temperature probe with an integrated connector, designed as a replacement part for water heater systems. The probe monitors water temperature in the lower tank zone and sends that signal to the water heater control board, enabling accurate temperature regulation. It is installed by licensed plumbers and HVAC technicians during routine service or control system repairs. The integrated connector design simplifies the wiring connection and reduces the risk of installation errors.

This temperature probe is intended for use in residential water heater applications where the lower tank sensing point requires replacement. The integrated connector eliminates the need for separate wire termination work, making it a straightforward swap during a service call. It is suited for situations where the existing probe has failed, is reading inaccurately, or has sustained physical damage.

Key Features
