Highest quality aftermarket replacement Harman & Heatilator Eco-Choice black wire ESP thermistor probe. Replaces HHT factory part numbers 3-20-00744, 1-00-00744, and 3-20-11744. The ESP thermistor probe mounts in the exhaust tailpipe and provides temperature readings back to the control board for proper function and operation. We recommend routine inspection and cleaning of the ESP probe. Please be sure to check your current ESP probe wire color prior to ordering; serial number outlines will be under our model specs. The black wire color ESP probe will replace all previous black and white wire ESP probes. If you have a red wire ESP probe, please see our other listings.

This will be the correct replacement for black and white wire ESP thermistor probes in the Harman Accentra FS, Accentra Insert, Advance, Invincible Insert, Invincible RS, P38, P61, P61A, P68, PC45, PF100, XXV, 44 Magnum, DVC 500, and Mark I stove models.
