Kombi sensör arızasını anlaya bilmek için açıklayacı video. Ustaya teşekkür etmek lazım.

Great video mate, please do more on components testing it's always good viewing.

Great video, clear explanation. I have central heating working fine but no hot water. I have been informed that DHW Thermistor could be an issue as boiler does not know of problem. Thanks I will try your video explaination. Jay

Hi really really like your video well explained really appreciated to you for share your knowledge with us Kindly please can you upload more videos like how to check boiler fan & air pressure switch & more like boiler fault finding & Diogenes Thanks a lot
A thermister can go open circuit when resistance increases/decreases so dont take it for gospel they are ok... (Had a few thats done it)

Excellent video well explained about thermistors Please upload more video about boilers such as diverter valve/diaphragm etc. Thanks

EXCELLENT VIDEO , as i was looking for a new meter after getting some funny readings off my tpi ez100 ..

great vid , replaced 3 of these in one year .. how come they keeping going wrong? never had to change one in 10 years and now three in less than a year ??

I believe when you tested the second thermistor the lead tips were touching and that's why you got the O.L reading....then when you moved you got a correct reading. You remind me of tradies I've hired here and cost me more $$$ then needed.

redrock1963 im just comparing these readings he got the first one was correct for room temperature, and the second one of 9000 is showing a temperature of around 27 Celsius.. I wouldn’t say that’s too problematic if anything the boiler might cycle on and off at lower deltaT room temps..
@martinb60793 жыл бұрын
If the lead tips were touching you wouldn't get a O.L reading (basic electronics testing). You would get 0.1- 0.9 ohms like he showed earlier in the video.

Just a quick question please , my heating hasn't been on all summer (turned to dhw only ) , however water has been hot as normal , pressure is fine , however water often goes cold , from these videos it sounds like the temp sensor , however pilot light goes out , would pilot light go out if bad hot water sensor and dhw on only ? Thanks

I may be missing something here but the 10k and second one at 9k are almost the same resistance so both registering around room temp. 80 degrees C would be about 4k - I am not a heating engineer so what am I missing here??

KaneInternational do a great set of clips on Flue Gas Analyses on youtube. But when i get a chance to do a vid on site i'll do one.

Does it matter which wires go on which terminal mine are independent, not in a block thanks

If I unscrew this from my boiler will water come out. Or is it sealed in a pocket

Ok so we don't have a fluug so what do we do guess what ohms it is to be set?
@possle11 жыл бұрын
Is the for all thermistors or do different ones have different ohms ratings.

Hi, when removing these sensors.. Do you need to drain the boiler or anything like that? Will water be behind the sensor?
@TippTopp816 жыл бұрын
MonkeyPumpkin some are dry pocket but I'd drain it to be sure.

11.000 to 13.000 oms is when the boilers cold what should it read when boilers running???
@leaturk116 жыл бұрын
These work by decreasing the resistance proportionally with an increase in temperature, for example 25 degress C to start at 12,000 Ohms, to 55 degrees C at 4,000 Ohms. As temperature goes up, resistance comes down.
