We all know that loose electrical connections cause multiple problems in appliances, heat being the most common one. But why does this happen? And what are the other negative effects on the circuitry and other components of the appliance? With a little help from our trusty friend Ohm’s Law, I will reveal all in this video tutorial. As a bonus, I'll also debunk a common myth that loose electrical connections cause a circuit to draw more current. Come with me now on a Journey of Total Appliance Enlightenment...




Dielectric Grease: Myths and Reality

Posted by Samurai Appliance Repair Man , in Appliance Repair Service, Samurai Wisdom, General Appliance Repair Wisdom 02 July 2015 · 1,438 views
dielectric grease
There's a lot of misinformation and mythology out there in the tech community about the use of dielectric grease on electrical connections. Some techs, knowing that the word "dielectric" refers to an electrically insulating material, mistakenly conclude that dielectric grease should never be used on electrical connections. This is based on a misunderstanding about how dielectric grease works.

Dielectric grease has two main properties that make it especially desirable specifically for use on electrical connections, especially in wet environments such as refrigerators and washing machines. In fact, this is its primary intended design use. Those properties are:

1. Low viscosity. This means that the grease will readily get out of the way of two metal contacts touching each other and flow around the contacts giving rise to the second desirable properly...

2. Sealant effect. As the dielectric grease flows around the contacts, it seals out moisture and oxygen preventing them from reaching the contacts and causing corrosion and/or oxidation.

Still don't believe me? How about Frigidaire tech bulletin RF1207:

Recommendation for Use of Dielectric Grease on French Door Models with Bullet-Style FFIM (RF1207)

Water intrusion into electrical connections within the FFIM causes intermittent interruption of ice production and melting of ice in the bin.

Symptoms: No ice in FF
Ice melting in the ice bin while FFIM is
turned on

Models Affected: All ICON, Electrolux and Frigidaire models with Bullet-Style FFIM

Solution: Use dielectric grease Part number: 5304485963

Part number: 5304485963

to improve electrical connections inside the FFIM. Application is recommended on EEV, TH3, TH1 and fan connectors, however it can also be used on any connector within the FFIM assembly. In general, if all diagnostics pass and the unit has 8.1/8.5 FFIM board yet the unit is either not producing or not maintaining ice, water intrusion into electrical connection can be suspected and dielectric grease may resolve the problem.

Bulletin is in the Downloads section here, starting on page 1-5.

ASTI, 2014, evernote
Well, mah bruvahs, heading out on that big ol' jet airliner from Logan tomorrow afternoon making that long haul to San Diego for the 2014 ASTI. Looking forward to seeing some of you there and will miss those of you who can't make it this year.

For my absentee brethren, the Samurai's got your six! I'll be taking copious notes and will post them all as PDFs in the Downloads section when I return. Additionally, if any of you have any specific questions you'd like me to ax the instructors, please post them as comments to this blog post (so I can keep them all in one place and make sure I get them asked).

Also, one more goodie: I'll be posting various highlight notes and photos from the conference to a public Evernote notebook. You can check in periodically to see what's new as the conference progresses. Access the Evernote ASTI notebook here: https://www.evernote...oidman/asti2014
