I have had my MES30 2 1/2 years and about a month and a half ago the element connectors burned through, thanks to all here who have posted about this issue. I has some new connectors that masterbuilt sent with the new element that I bought for my MES40 so I spliced them in and all was good till last weekend. I was smoking some chicken and started loosing temp, switched the food to the other smoker and saved dinner. This evening I opened the panel on the back of the MES30 and the wirenuts and melted and the terminals look corroded.
I guess this time I will hit lowes or home depot and get some high temp wire and connectors and replace these two connectors from end to end. Any sugestions on cleaning the ends on the heating element? And would there be any advantages or drawbacks to soldering the connectors rather than just sliding them on? I am thinking the solder would make a much better contact.
