Upon arrival, customer notified me that she utilizing the toaster in the kitchen. The outlet next to the cooktop on the left sparked and appeared that it was catching on fire. The customer unplugged the toaster. The outlets on the right of the cooktop are working as intended. We are going to conduct a diagnosis to determine where power has been dropped and provide an option for the customer to safely restore power back to these locations. Customer has two outlets on the circuit that have been damaged. These outlets have burning around the terminal connection points. It appears that they were poor connections made for the devices which caused them to burn and spark. The existing devices are not safe to be tied back into the electrical system. It is my recommendation to replace these devices so the customer can continue to utilize the circuit as intended.
