Harman Heatilator Black ESP Thermistor Probe 3-20-11744

Harman Heatilator Black ESP Thermistor Probe 3-20-11744

Q: Will this work on 3 knob Harmon pp38+ ?

Describe 3 knob? If you mean 1 knob for feed, 1 knob temp, 1 knob for air flow speed, yes it will. Just plug ESP sensor plug into one you take out. After you install new, make sure stove is unpluged from electrical source until completed.

Q: What is the length of the wire I will ned this for my pb105 Boiler i need it to be about 8 feet in length of black wire.

It's probably 2 feet. Maybe 3 at most. It's just 2 wires. U could probably splice wires in and just add the length u need

Q: Anyone know of this fits the Harman absolute 63?

I’m not sure about the harman 63. I have a harman that is from 1996. The reason I changed the probe was because my stove would run for approximately 1 hour then shut down. I changed the probe and my stove has not had a problem since. There is videos on Utube or google the year model and make of your stove. Good lunch hope it works out for you.

Q: Dies it work for a harman xxv?

I do not know. But, look at description and see if...what Harman models this part will fit. Other wise search by your Harman model number.
