Lights flickering 3 months after fridge added to circuit
I added a fridge (couple of years old but new to me) to a circuit three months ago. The 20 amp circuit had two exterior ceiling fans rarely used and two pendulum lights in kitchen. Have not had any issues with the lights until yesterday. Two days ago I Took out drywall on back of the wall of the dimmer switch that controls the lights. Was able to pull off with out any real banging. Next day noticed light flickering and even Temporary loss of power maybe 20-30 seconds with nothing and then popped back on (breaker didn’t trip). I worried I had a loose wire from working on the wall but don’t see anything disturbed in dimmer. And lights stay steady when I jiggle and test connections. I checked all connections mad when adding fridge and all are tight. I then found that if I remove the fridge the flickering stops. So I think that’s the culprit but when I but the fridge on a separate circuit with 6 can lights no issues everything holds steady. Any ideas on what to check next. If/when I add the fridge back to pendulant lights the flicker starts again.
Thanks for any advice

Thanks. I reworked the connections in the wall I had been working on and still the flickering continued. Remembered that there was one other light on the circuit I never use. It was flickering as well. Picked up a new breaker and switched it out and that seems to have fixed my issue.

Excessive use of electricity than available tends to result in lower voltage, due to voltage drop that naturally occurs in wires when amperes draw is increased, and also due to loose connections. Loose connections will heat up tremendously long before the current (amps) permitted by the circuit breaker or fuse has been reached.
Now, a loose neutral can cause overvoltage that will damage and fry electronics including microwave ovens and some washing machines.

Voltage and frequency are controlled within a narrow range by power companies due to law. This does not apply to lightening striking the wires from the utility to your house. Do you have a standby generator without over voltage protection?
