Does the pilot light and immediately go out when you release the knob, like the thermo isn't getting hot?
The flame should be well into the thermocouple without adjustment. More often than not its fluid in the lines keeping the flame from running at full capacity. Compressed air helps to flush moisture out.
The wires should make a complete circuit fro the thermo to the valve.
are these exact fit?.doesnt say model mh4b.and the one in the little buddy clips in with no nuts but if it does work i could adjust it better.it only clips in 2 positions now.this is the round heater that goes on top of the prop tank.
Yeah when it lights it works fine.this heater is clean and like new besides being 2 years old but only used 3 times last year.stored in a bucket with lid.ive got the thermo couple bent to the outside so the flame is right on it.it was over the gas port more before and not in the flame.it lit a few minutes ago and it’s freezing out.but tommorrows a different day and it probably wont light.lol.using full 1lb propane tanks.warm or cold doesnt seem to make a difference.just moving the thermo couple all over gets it to light.
When it happens again try pushing your "off" button 4 or 5 times and then try it again and see if it stays lit. I had the same problem you are describing and after tearing mine apart three times I finally figured out that the "off" button was sticking and not allowing the heater to stay lit once I let go of the "on" button. Was a real pain to find, I kept thinking it was the thermal couple as well until I started checking the switch with a multimeter and found that it wasn't closing when I released it.
I had the same issue with my Hunting Buddy a couple years ago. After some research I came to the conclusion that my thermocouple was mounted incorrectly from the factory. There are 2 notches on them, mine was mounted on the top notch (yellow arrow in pic). I moved it to the bottom notch (red arrow) so it is more into the flame. It is a major pain in the arse to dis/re-assemble the heater but ever since I did this it's been working great. The pic is the proper mounting position of thermocouple.
