If you have tried several basic troubleshooting to save your cooker and none works, YES, YOU SHOULD.
Although following some troubleshooting steps, such as checking the socket and the adjacent outlet, resetting the circuit breakers or control, or replacing the extension cord or power strip, you may be able to fix the issue of your power light blinking.
Like the best broiler pans, crock pots are designed to cook food at a low temperature over an extended period, making them a convenient and easy way to prepare food and meals.
However, if a crock pot is not functioning correctly, it can be hazardous to the user.
Note also that if the crockpot is still under warranty, attempting repairs yourself may throw away or void the warranty.
If the power light blinking problem persists, it's best to contact the manufacturer or a qualified electrician for an answer.
