electric throw plug contact remedy?...

[Ace Crysler]

Keep my electric throw handy and near me in case the temperatures did
and for several years now, it has done a good job warming me up.
However, a month ago, I started getting no heat. At first I thought it
was the wiring or controller, but it turned out to be where the power
cord plugs into the unit. Don\'t know if you\'re familiar, but there are
three copper, brass or other metal pins that are mated to hollow
cylinder pins of the same size in the blanket. The pins are molded into
a plug and the cylinders are part of the socket in the blanket. What
could I do here to prevent future opens? I never unplug this, only to
see what was the matter recently. Thought I could maybe coat the pins
with something, but not sure what. Thank you.

Do what I have done for years. Work the connection every so often. OR
unplug & plugin a couple of times every few months. SIMPLE !

I\'ve used Dow Corning #4 Dielectric Grease on connectors that run warm
and it improves the connectivity so they will run cooler and failures
are further apart. A very thin film of grease seems to do the job. It
improves the junction by reducing mechanical resistance to insertion.

At least in our customers pinball games and the electrical wiring of my
motorcycles...

While I don\'t know if dielectric grease will help the OP at this point (prob many high current arc events inside that connector), I\'m a huge fan of dielectric grease and don\'t put together any electrical contact without a bit of it. It deprives contacts of moisture and oxygen and reduces plating wear from vibration.
