Will this fit mh125ktr?

I have no idea, if you are looking for a replacement electric eye, I would say this would work. This was the right part for my heater and it has worked ever since.

Will this work in a master heater?

This is an industry standard part. The adapter plug should make it fit electrically. Mechanically they are all the same. The boot is rubber so if yours appears a bit different you can swap that, but I believe even the boot is standard.

What are the 2 extra pigtails for?

They are extra for a different model. This fits muptiable modles.

Will this fit a mh175ktr ?

It should but also check fuel line from tank, that was my issue and also a friend of mine. Heater would try to light and sputter, after replacing sensor still same issue. That was when I discovered fields line from tank was cracked at bend

Cheap, and works. Plug didn't fit, but the extra pigtail helped immensely.

Excellent product - cheaper than the alternative that is made for my heater, and way better made than the stock one. The plug didn't fit my control board, but they included an extra pigtail for adapting to other heaters - so I just clipped the plug off of my old photosensor, soldered to the pigtail and plugged it in.Photosensor works perfectly and resolved my issue. Three thumbs up.

Sensor for kerosene salamander.

Ended up keeping for a spare replacement. Original was not bad. Needed to replace degraded fuel line, and my problem was solved.

This is the one you want

This is the one you're looking for. Others I got from Amazon were far too short and did not perform as stated. This one is ideal; the leads were 15 inches long and worked well with my large Reddy heater.

This took 3 weeks to deliver. I have no idea why. Ive had stuff shipped from China show up quicker. Aside from that, the part fixed the problem of the flame going out and tripping the the breaker on the heater.

This part ages over time so it’s good to have a spare

Quick fix. No issues. NOTE: you can’t just short this out to bypass it. It is required to see the flame. If the heater stops even when the flame us lit, you may have a spider nest in the sensor area. This fixed mine as mine had a nest in it, but after cleaning it out, the unit ran for about 15 minutes. After cooling, I got another 15 out of it.This part ages over time so it’s good to have a spare.
