Inspect the power cord for visible damage. If damaged, replace the power cord with a new one. Ensure the toaster oven is unplugged before starting.
If the toaster oven was exposed to water, allow it to dry completely for at least 24-48 hours. After drying, plug it in to check if it powers on.
Test the thermal fuse and replace it if it is blown. This may require disassembling the toaster oven to access the internal components.

power cord has a broken wire

Cut out the bad part of the wire and use twist wire connectors or replace the cord. A three-prong cord can be used, but grounding to the case is not recommended.
