Anyone else have this issue? I was by my tank and caught the smell of burning plastic. I started looking around and noticed my MP40 QD controller was blinking red. I picked up the controller and it was extremely hot. The internals got so hot that they melted the exterior of the case, that dimple on the backside is where it actually melted. I looked all around MP40 but there is no explanation for this happening. The magnets were aligned perfectly, there was nothing blocking the impeller, I just cleaned the wet side a few weeks ago. I double checked and made sure that I'm using the right size of spacer for my glass thickness. I'm glad I was home and awake when this happened. I've had this MP40 less than a year. I want to give a shout out to ecotechmarine their customer service is top notch. They had me send back the original unit and sent me a replacement unit.
