The trainer on this video is a top class, my trainer in British gas was a low class mappet 🤣🤣

What should the volts reading be on the multimeter?

That's was very well explained! Understand how to test fan now.
Maybe pumps, diverted valves, gas valve next? :)

Hi im working on a baxi 105 he and its showing an air pressure problem. The fan is running with 240v at it and 34 ohms across it, the boiler lights when i manually make the air pressure switch by sucking on the tube. Ive also changed the aps with no joy. The fan seems to me to be running a little bit slow even tho its spinning freely and isnt stuck at all and has the correct voltage to it, Any ideas?

[darrenkelly]

Had a problem where, fan runs fir few seconds then stops . And continued to do so without ignition happening. It sparks but no ignition. When I took hose off the spigot fan runs properly but still no ignition, any ideas would be appreciated.

Great video, can you please let me what is call the one what you recommend to use it to check APS not to blow .from where can I buy it
Thank you

[crosswaychurch]

which hose goes to which outlet on the new valves? suggestions for securing the new valves since there is no mounting bracket like on the one it is replacing?

1:22 me watching this after I tested the pressure switch with a multimeter and blowing air into that presure pipe 🤡
I put light pressure thou, and I could hear the air going out on the other orifice of the switch. All good for now 😅

Can anyone help please me with my baxi boiler. The fault on fan or fault is flashing

[alanbroderick]

So did he say with the fan running the switch goes from normally closed to normally open? ??

hello uncle, great video, thank uncle, 🤣🤣🤣

[russelldouglas]

The boiler looks surprised almost embarrassed that its fronts been removed 😳

[Eva_lily]

Anyone had a fan running slow on these and not making the aps?
