Hi!  
Looking more closely, the connection to the V+ port for the motherboard melted and becomes very warm when turned on. This seems similar to: [12V Power Supply Connection to Motherboard Melted](https://www.evolver.bio/t/12v-power-supply-connection-to-motherboard-melted/263), although the voltage delivered from the power supply on our eVOLVER seems to hold consistent at 12V. The stir and heating functions operate for a few minutes occasionally, usually after turning the unit back on, and then shut off. Now I am wondering if they function until the connection overheats?
