The best solution to electrical interference is eliminating its source. Here are some easy steps to try:
- Turn on the appliance that is experiencing interference. Next, flip the circuit breakers in the home off, one-by-one. When the interference disappears, you have found the circuit that is causing the interference.
- To confirm your conclusion, turn the circuit back on. If the interference returns, identify everything on the suspect circuit and begin turning the items off, one-by-one.
- When the interference disappears you have found the culprit.
If this does not work, try tuning a portable AM radio to a low number station and follow the actual line of the circuit from the breaker to the outlet for each appliance, while the appliance is operating. As the static on the radio increases, you are nearing a potential source of interference.
Loose connections or bad wiring behind a wall, panel or outlet could be the cause. Have a qualified electrician conduct an inspection of your wiring system to eliminate the interference conditions.
If you cannot identify the problem within the home, there is good chance the interference is coming from a neighbor or the utility. Call your local utility and tell them you are having interference problems, and you believe it's originating outside your own home. They should be able to help.
