Learn from my mistakes #237. But NEVER do what I do, call a professional in the specific area of expertise!!
I washed and dried the clothes and shoes I wore after working in my crawlspace, doing some insulation repairs. Shoes banging around in the dryer, door pops open so I blocked the door with the bifold door to keep it closed, That worked, BUT it stopped heating! I took the front off, checked the resistance of the heat element FAIL! Looking inside the element housing you can see a small piece of the metal element reinforcement, melted and black, and the element coil broken next to it. So, I am waiting for a new element to arrive. Lessons learned. 1. Don't work in crawlspace ever. 2. Listen to the warnings of the dryer door. 3. Buy new shoes after each use. 4. If you must work in crawlspaces and must wash and dry your shoes, either dry them in sunlight or place more clothes in the dryer so it does not bang around causing the HOT heating element to hit something it is not supposed to! The excessive vibrations largely caused the failure.
As for why didn't the breaker trip, I believe there are a couple reasons, 1. Because this is an older 3 prong type cord connection, without a specific Equipment Grounding Conductor, 2 Hots, 1 Neutral. But also, that the short was a quick touch of the element to the housing and did not generate enough current to trip the 30 amp breaker. Modern standards are 4 Prong connections, the 4th being a separate ground, and not just tied to the Neutral the old way, this serves as an added safety measure. Also, having GFCI protected dryer outlets and laundry outlets. In my case a GFCI protected dryer circuit may have tripped in my case, as they are designed to trip between only 5-6 milliamps. Similar to GFCI's in Kitchens, Baths, Basements and other Wet Locations.
