Hey Mary! Thank you for calling Kings Electric & A/C for your electrical upgrades. Today I was called out because of some sparks behind the oven and tripped breakers. I opened up the panel, read lol circuits and everything was good voltage wise. I recommend you replace all breakers in panel, if you want to make everything correct, the actual panel should be replaced with a new. If you have any questions or concerns, please reach out. Your electrical technician, Xavier
