COMBI BOILER,TEMPERATURE SENSOR TEST,THERMISTOR TEST 

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

Good job and thanks for giving this information.

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

Yes, .more component testing vids please. Pumps, valves, boiler internals. Many thanks.

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

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)

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'll try to do a clip on air pressure switches in the next few days.

Is the for all thermistors or do different ones have different ohms ratings.

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

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.

any chance of a tutorial on flue gas analysers please

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

Would this explain why the hot tap runs hot then cool ?

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

well explained thanks.

Please make live and dead test of each component of boiler

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??

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.

Very well explained tho

Ok so we don't have a fluug so what do we do guess what ohms it is to be set?

Hi, when removing these sensors.. Do you need to drain the boiler or anything like that? Will water be behind the sensor?

Where do you put the probes on a single pin sensor?

Hi,my boiler keeps shutting down when i run a bath,could it be a faulty thermister?

11.000 to 13.000 oms is when the boilers cold what should it read when boilers running???

Hello sir l have sensor boiler temperature, 3 wire cable color : Red,blue and white but l dont now type of sensor RTD or Thermocoule . Please help me sir Thank you…

Only if the thermistor is an NTC.

tipptopp, you sound like a Wiganer, are you? good vid BTW

I'll try to do a clip on air pressure switches in the next few days.
