I was able to diagnose and repair a HW heater because of this video....Thank you Craig (AC Service Tech)

Lots of technicians have knowledge and ability, but can't convey it to others very well! Sir, you are the man! Thank you, I learn so much from your presentations, one and all!

[stuckinmygarage]

Wonderful explanation! No filler; straight talk; best show and tell. Thank you!

[Keooo]

I love this guy man. I wish I was your apprentice! Master craftsmen in this field!

[codyspendlove]

Rarely to I find exactly what I am looking for on the first YouTube search. Thank you! This was perfect.

You just saved us a ton of money! My parent's hot water heater quit working and the pilot wouldn't stay lit. Replaced the thermocouple and still the same. Figured it was the gas valve which couldn't be replaced so my dad was on his way to get a new tank. Watched this and saw the thermo disk can be reset, sure enough that was it! Thank you!

Do you teach at a vocational school? I've been in the trade for 35 years and find you to be an excellent instructor. I couldn't do a better job myself.👍🏻👍🏻🔥

I’m so glad you added this video, because thermopiles are different. Thanks, this is an excellent tutorial.

Your working model setup is absolutely the best on the web at educating people interested in dealing with issues associated with this particular gas water heater control‼️Thanks for making it available👍

[dougkoudelka]

Old style manual valves work without issues, some for decades. Modern systems like this are problematic garbage it seems judging by comments online. The "energy savings" of these Honeywell garbage units are gobbled up by replacement costs as failures are common. Progress? Nope.

Very good and compact unit. Fits well under the sink and provides IMMEDIATE hot water!!

[nolanzorn]

Amazing video thank you. I feel fortunate that this is the same model I have. Most videos I see cover a non integrated thermocouple setup. And for only like $40 you can replace the entire pilot assembly to basically rule out 90% of problems you described. Thanks a bunch!

Awesome! Sometimes customers asking to check the water heater. Now I'm totally know how it's made. Pretty same technology, wall heater, fireplace, old-fashioned furnace millivolt gas valve. Thank you!)

The best water heater video ever! thumb up for this demonstration of the inner working of a water heater in a open demo of the workings. Helped me get my water heater back to working order. THANKS!! THUMBS UP!

[rawdiscamaro]

Hello . Is the solenoid for the push button replaceable? My pilot cuts off when I release the button

[tjinytjiny]

I changed out a thermopile and my WH still wouldn’t fire up. I finally found a video that highlighted the importance of installing the thermopile all the way in. What I thought was all the way in due to hitting against a cover was not. I reinstalled the thermopile all the way in after loosening a screw the initial video never mentioned. The result of the correct installation of the TP, was a working hot water heater. Thanks for the info here you provided, I’m sure it will help some..

Very thorough, educational and beneficial as usual !
Hope you had a good Christmas Craig !
Happy New Year

This man is the best technician around the world

All these years I never knew how a thermocouple or thermopile worked. I only looked it up because I saw the flashing light on some water heaters and was wondering how the light got its power. Very ingenious concept.
