Heat builds up fast. And while everyone worries about the heating element burning out, that&rsquo;s usually not where the real trouble starts. The real killer? The lead-wire connection.</p> <h2 id="the-slow-burn-of-bad-wiring">The slow burn of bad wiring</h2> <p>Here is the thing about standard wiring: it just isn&rsquo;t built for this kind of abuse. In a lot of the cheaper units out there, the lead-wire is basically just shoved through a sleeve and called a day. But heat does weird things. It makes insulation shrink. It makes it crack. Once that seal gives way, it&rsquo;s an open invitation for dust and moisture to crawl inside. That’s when you get carbonization. If you see a unit where the seal is just a messy dab of silicone, you&rsquo;re looking at a ticking time bomb.</p>
