Question about Refrigerators

2 Answers

I have a Maytag model MBF1958WES2 refrigerator. My problem is that it is causing interference on AM radio reception in my house. I do not think it is coming directly through the house wiring(at least not exclusively) since a battery powered portable radio also receives this static. My belief is that the refrigerator is somehow utilizing the house wiring as an antenna and is actually broadcasting the static through the air. If I pull the plug on the refrigerator there is no static. If I operate the refrigerator on a small generator there is no static. This is a particularly bad problem for me because I am in the business of restoring vintage tube radios. This refrigerator is only 4 months old. Please help!

    I can't accept that as a solution. If you will note in my posting of the probnlem, I said that I ran the refrigerator off of a small portable generator and when doing so, there was no static problem. The point is that the portable generator had no ground whatsoever. Bob.

    Thank you very much for elaborating. That makes sense to me now. I will investigate. Thanks again, Bob.

AM Noise is usually a sign of a poor ground somewhere in the wiring- I'd see if you could get some chicken wire, a voltage source- and form a Faraday cage in the room to see if that stops interference. Another thing is to have an electrician (or you if you are so inclined!) check and make certain that your wiring is properly grounded.

I'd also see if you could run your refrigerator on an UPS (basically a way to condition the power since it would have its own ground and would essentially remove the issue of a poor ground, but it would still be there lurking....)

I'd say the issue is in the wiring of the house- and the best solution, if there is an issue with wiring- is to get a qualified electrician to check it out.

It sounds like that you have a bad ground on the refrigerator receptacle. Or do not have a ground wire on that circuit. Check all of your ground wires. Including the ground from the ground bar in the electrical panel to the ground rod driven outside the house. This is a grounding issue. If you get the refrigerator grounded it should stop this frequency.

    The ground is contained in the generator. The refrigerator is using the neutral for a ground when plugged into the wall. Which will use the whole house as an antenna. When plugged into the generator it is contained to the generator.

How do i get my WR 100 to stop squeaking durring a weather emergency?


Have you tried tuning to different NOAH frequencies to see if one of them gets better reception? Also, if the radio is close to other electrical devices, they could be causing interference with your weather radio reception.
Just a couple ideas tossed out there.
Good luck.

Poor reception when trying to get MW


Poor reception or with heavy noise aas the interference is very high on the MW. If there is no signal strength then the fault can be due to faulty RF in the radio, poor MW oscillator settings or a faulty IF settings.
Also a faulty antennae can cause poor reception and pick of stray signals.
Check for other interferances from household applicances.

Hi, I'm about 40 miles NW of Chicago and reception here is not great. I like to listen to AM radio. I usually use my speakers just to listen to CD's, but I decided to try my Acoustic Research receivers...


First make certain the CD player isn't on when the radio is on. CD players cause inteferance with radio's. Apart from that you will need a good aerial. If that doesn't improve it then it could be down to local conditions -hills, power lines etc, blocking the signal. Also check there's nothing around the house that might cause interferance to the signal.

CAN SHORT WAVE RADIO CAUSE DIGITAL TV RECEPTION PROBLEMS


Theoretically, they could. The digital TV signal is still sent via radio waves, but the frequencies should be so far departed that they have little or no effect on each other

Causes interference with radio, tv


You could possibly add a metal shield around the electronics in the dishwasher and ground the shield with a wire to the dishwasher chasis. Don't know if this would reduce the EMR enough to stop the interference with the radio, but there's a chance it would.

Kenwood cd reciever model 241-Sa, fitted by halfords, am receprion very poor, interferance. What do I do? Thanks


Modern AM reception is usually quite bad. We are used to the high quality sound from other formats and FM, AM has a very compressed frequency range so will always sound poor in comparison. The interference could be due to poor earthing or suppression on the electrical equipment in the car. Usual suspects are ignition, wiper motors and fans. A suppressor between the +V and earth usually help, fitted as close to each device as possible. The devices causing the interference can be pin pointed by turning one electrical item on at a time and seeing if it causes a problem. Another issue is that a lot of modern vehicles use the rear screen demister as an aerial, which can cause bad reception and interference. An external aerial is always best.
