"Featured Content Triptych Setup Doc" contains the 3 featured items - image, descriptive text, and button, that you can edit to change the image, text and link/button text as appropriate for this group. If there isn't already a 3-box widget showing on the home page for this group, to display the document, you will need to get someone with Admin rights (one of the Devs or Pauline's team) to add a Wiki Viewer widget for you and insert the url to the document. From then on, you will be able to update the content of that widget by making changes to the document. "Featured Video Setup Doc" lets you embed a video - YouTube, Brightcove, or an image that links to a document somewhere on the site that contains the video - and that can also be put into a Wiki Viewer (in the skinny column) using the url. From then on, that widget can be updated by changing out the image/link or embedded video that is in that document.Wiki Page: Featured Video Setup Dochttps://community.element14.com/challenges-projects/project14/simpleelectronicrepairs/w/setup/26971/featured-video-setup-docWed, 10 Nov 2021 04:40:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:6e81b506-0bab-4f86-af4e-734e1b76a4c9ChristyZfeaturedVideoFile: Loewe-Opta Meteor Type 1781Whttps://community.element14.com/challenges-projects/project14/simpleelectronicrepairs/m/managed-videos/37912Mon, 11 Oct 2021 20:22:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:799d50b2-1949-44c4-8af8-d8b5a53673aakk99Radio Loewe-Opta Meteor Type 1781W More info: http://www.radiomuseum.org/r/loewe_opta_meteor_1781w.htmlMeteor1781WradioLoewe-OptaradiomuseumFile: 1970s Sears 8 track repair part 1https://community.element14.com/challenges-projects/project14/simpleelectronicrepairs/m/managed-videos/17650Fri, 08 Oct 2021 02:06:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:dc622b69-eda8-49ab-b4ac-7e3e3c0e5c6egam3t3chSince I know I am going to do a follow up to this one I will label this as part 1 not sure when but I will make sure to make more on this unit was fun to play around with.

It wouldn't matter .... Given that your friend was able to 'knock' it into life, suggests the contacts are the issue, not the failure of the coil or the mechanism. If the load was slightly inductive, there would be some pitting, and this might be able to be polished out ... but it would come back again later. At least you know what the cause is, and it's a relatively easy fix, even if you need to do some tricky wiring next time to fit a different style relay.

The regulator reported that the heater switched 27 000 times before failure. This is probably true, 16 years, meaning ca. 1 700 times switched per year. This is ca. 4,6 switches a day (during summer, only water is heated, but the boiler is operable for the whole year). I suppose the reported value is only for turning the heater on, which would mean 54 000 switches of the relay in total. Unfortunatelly, I can't find a datasheet for the relay to compare this value with an expected life.</description></item><item><title /><link>https://community.element14.com/challenges-projects/project14/simpleelectronicrepairs/b/blog/posts/repair-of-a-cng-boiler-control-board?CommentId=c95a2c84-93a2-41c6-ab8a-b94483a744f0</link><pubDate>Fri, 05 Jan 2018 22:41:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:c95a2c84-93a2-41c6-ab8a-b94483a744f0</guid><dc:creator>shabaz</dc:creator><description>Hi David, Awesome job(s)! This series on repairs is really great. And good seeing the massive savings by not throwing out hardware. Spare parts for boilers are really expensive, and of course schematics are not always available, so the system is often against those who wish to self-repair : (</description></item><item><title /><link>https://community.element14.com/challenges-projects/project14/simpleelectronicrepairs/b/blog/posts/repair-of-a-cng-boiler-control-board?CommentId=c1c3bdc5-afc9-4476-af11-9b034504a9f0</link><pubDate>Fri, 05 Jan 2018 22:23:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:c1c3bdc5-afc9-4476-af11-9b034504a9f0</guid><dc:creator>mcb1</dc:creator><description>I am glad the board was originally soldered using a lead solder, so I could do the work easily.
