This past winter, our 3 year old Mini started to smell like it was overheating....the "new paint smell", if ya know what I mean. Found that the convection fan stopped running. After some testing, found the fan was still good; then decided to attempt a CONVECTION FAN TRIAC replacement. There was NO WAY I wasn't gonna try this before spending $350 or so for a replacement PC board. Ordered triacs (& the opto-isolators that feed them) for the convection & combustion fans. They are fairly cheap, so I bought a several of each. Thought I'd wait for warmer weather to do the repairs. I temporarily bypassed the electronics to run the convection fan directly from the AC power outlet until the day of repairs. While waiting for warm weather, the ignitor died. Surprised it only lasted 3 years! Fortunately, I already bought many replacement parts for this thing, and had that laying around. EASY FIX on the ignitor. I also installed an IN-LINE FUSE to the ignitor to protect the PC BOARD if it were to ever short to ground. Well today was convection fan repair day. Swapped the triac, and VIOLA! All's well that ends well! See pics (pic labels aren't perfect, but good enough to complete MY fix). If there were a sticky for the Enviro Mini, this post belongs in it, lol.
