Excellent video John . welcome back I look forward to seeing more of your no nonsense videos

“Hello I’m JW”….. The main man is back! The most arid, practical theory channel on the internet. Reminds me of a 1970s Grammar School master. I love it.

Glad you are back in the YouTube community again.

Thank you John for that simple video. I knew how to test an element but as ever you make it very clear and concise for those who may not have that knowledge. It's great to see you back on the channel. I have learned masses from your videos over the years.

[ningis]

Cheers John.... Concise and to the point. Perfect.

[ebarreira]

Nice to see you back Jonh.Great explanation

JW Tested the best label you can ever expect on a heating element

Thank you for your thorough and informative videos.
I always learn something watching them.
Thank you for sharing you considerable knowledge.

Interesting stuff John. Good to see a video from you. Thanks

[shiamjad]

Welcome Back John... want regular videos from you.

[rayc]

Very informative John. Welcome back and many thanks. 🤘

[rogerfarnworth]

Thanks John, no nonsense explainations, precise and clear. Just like my old college master!
Going to treat myself to a multimeter now before replacing new elements and/or thermostat on my old Dimplex storage heater.

I was initially resistant to watching this video but I was happy to see that it was quite a hot topic with the element of surprise in the storyline. Once I warmed up to to that notion I put down my burner phone and proceeded to the thumbs-up icon to lend my support. Thank you for the video. p.s. Very nice meter! I would happily be a beggar for that Megger™. Cheers from So.Ca.USA 3rd house on the left.

Sure it’s just grand to see Mr Ward back ☘️

John, I like this video and your channel, so don't misinterpret what I say next as throwing shade. If the goal is troubleshooting, I'd be inclined to test input wiring first. Remove the element, then put a 240V incandescent test light between input and output wires, then turn it on to see if the circuit and its driver can deliver the power required. If the light glows brightly, you've ruled out voltage drop, blown fuse, open circuit, upstream short to ground, high resistance neutral and failed driver as a cause. I've often wondered why technicians don't usually test the element directly. Not all have a megger on hand. After the element is removed, the short through a corroded area could be disrupted enough to create a time wasting false negative. So efficient work flow is to prove the circuit is OK with a 1 minute screening test and then swap in the new element with confidence.

Always enjoy your video''s and the information they contain .Thank you .

Welcome back, and thanks for the good video!

There is a new element on the periodic table and it's the most important element of them all. . . . It's abbreviation is JW

nice to see you posting videos again...

Long time no see. Good test. Thank you:)
