What_The_Frag Posted March 20, 2019 Share Posted March 20, 2019 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.

chewie Posted March 20, 2019 Share Posted March 20, 2019 Too bad you didn’t open the driver and take pics. I’d love to see that. That looks like the area where the RFchip is. The indentation looks curious to me. Did ETM let you know what happened? Gotta love their customer support! Quote Link to comment Share on other sites More sharing options...
albertareef Posted March 20, 2019 Share Posted March 20, 2019 Pretty scary - good thing you were home. Would also be curious what actually failed but seems unlikely they will either diagnos or share. Quote Link to comment Share on other sites More sharing options...
What_The_Frag Posted March 21, 2019 Author Share Posted March 21, 2019 Here are some shots of the circuit board. I haven't heard anything back from Ecotech as to the cause, I'm going to ask them out of curiosity... and a sense of self preservation lol.

chewie Posted March 21, 2019 Share Posted March 21, 2019 Ahh. Opposite of the RF chip. Let us know what they say... Quote Link to comment Share on other sites More sharing options...

NateDawg Posted March 21, 2019 Share Posted March 21, 2019 The little tanish colored box next to the ic chip, where the damage was done, looks to be a capacitor (kinda hard to tell without seeing the original color/numbering), either the component failed or someing further down the line caused a voltage spike that was more than the capacitor was rated for/could handle.
