Gas Training - How To Test a Thermocouple - Multimeter Training 

Been on several of Roy's courses. One of the best. Good to see him still sharing his knowledge.

Loving these new fault finding series. Well done Allen

I am almost finishing my gas course in leeds College, but honestly, I'll come to viva Gas Training for the rest of my course, which I like to do, and the only reason is allen and Roy's ( he is a live gas bibles). I'm so impressed by these guys knowledge specially Roy's. Looks after your self men.

I’ve been through the Baxi training with Roy and he was brilliant and knew his stuff. Thanks both for this video. 👍

Thanks for posting this. I recently purchased an old Eastham Maxol 41 camping oven. Couldn't figure out why it wasn't working till your video explained how the thermocouple combined with the flame failure valve worked. After that it was easy to test the operation of the valve and thermocouple. Explains why I couldn't get it to light first time. I didn't hold the button in long enough. Thanks again.

Thanks To Roy & you Allen . Much appreciated

Few years back the only videos on testing thermocouples were from America. No commercial training centre in the UK ever touched on the practical experience of testing and proving components within/outside the central heating system. Brilliant video!

Been on a course with Roy in the past he is Brilliant

Great video as always gents. Wish I would have had someone like yourselves as my instructor.

Love these videos brilliant!

A great informative little video. Well done lads. 👍

Great, thanks Allen and Roy :)

Great basic training, sometimes it’s the simple things

Love your videos

Love your videos here in the states!

Thanks Alan

Very helpful thanks guys 👍

Very good video nice a simple and easy explanation many thanks

Thank you Allen and Roy, a great video, and well explained. I’m liking these new Roy videos, thanks both and Viva. A couple of questions if I may? In a video Roy mentions no need to have mega expensive multimeter, I have an Amprobe 500 basic and mislaid an Extech, should I upgrade to a Fluke, or will these suffice? Is there going to be a video on Combi boiler sequence of operation?

Excellent stuff

Great video, thanks Roy and Alan, unless you know how the simple things operate faults are not so simple to diagnose.

These videos are great ,I feel smarter already . How do you test the mag unit if it is an intermittent fault? Thanks

Excellent tutorial

Great struff! Is it possible to repair a thermocouple?

TC's are still out there but don't see many boilers now with them. Last one I went out to would be over a year ago.

Where we can find the part used in the first test method?

Good stuff! 👍🏿 one question is TB 118 part of the ACS?

😍😍😍

Also, I’ve never replaced a thermocouple, can a universal thermocouple be used, or does it have to be manufacture specific?

👍🤓👍

Can't remember who but someone makes one off them testers got one in a bag some place. Works better than multi meter tested some that where obviously burnt out but was getting 20 odd millvolts

Why brand new thermocouple makes just 15mV ? Pilot flame is good and "touch" the thermocouple perfectly.

Great video again Allen. Does Roy have his own RU-vid channel ? Or does he have an Instagram account?

I have a regin thermocouple tester 😉

First day on initial acs, already have a headache

Roy the "sooper dee dooper trainer" didn't even mention what the acceptable voltage range is for a thermocouple 🙄
