This is not really my area of expertise, but i would venture to say it has to do with your neutral wire in your outlets. If your house is older, the neutral, which is tied to the ground in the panel, was not sized to hold the modern electronic equipment. WIthout getting to technical, electronics create what are called noise and harmonics on electrical wires which is the static or "breaking up".

A larger neutral should fix it but that would involve at least rewiring that outlet with a straight shot to the panel and maybe upsizing the neutral in the panel. I would get an electrical engineer or someone who has worker with a lot of electronics opinion beofre you go to crazy though. A straight shot cable from your tv outlet to the panel should fix it though, i would bet.

Hello

Plug the microwave into the outlet if the microwave won't power up. Make sure the plugs on the microwave match the type of outlet. A four-pronged outlet can only be used with a four-pronged plug. Same with three-pronged outlets---they only work with three-pronged plugs.


Inspect the plug. Make sure it hasn't been cut or tampered with. Four-pronged plugs can't be cut down to fit a three-pronged outlet. Three-pronged plugs mustn't be forced into four-pronged outlets. A three-pronged plug mustn't be used in a two-pronged outlet, either.


Replace blown fuses, or if there's a circuit breaker, check it for tripped breakers. Sometimes the trip won't be obvious, so cycle the circuit breakers. Turn them all the way off and then back on again.


Plug another appliance in the outlet. You will find this easier with three-pronged appliances. Simply plug a toaster, or other appliance into the microwave's outlet, and see if it works. If it works, you know the problem is with the microwave, not the power circuit. Have the microwave serviced or replace it. If the toaster or other appliance doesn't turn on, you know the problem is with the circuit.

Hi when the philips bluray player is playing and someone switches on a light switch or appliance anywhere in the house the bluray player switches off for couple of seconds and then turns back on any idears...


The voltage of the mains in your house is very low and when another appliance is turned on and the current it draws during the startup procedure is very high it drops below what your player can use - so it simply shuts down. When the appliance goes in normal mode the current drawn drops = the voltage goes up and you player restarts. Verify the voltage settings of the player and, if necessary use an UPS.

GT-11 Lights up when near my granite counter top ????----Also Nearly All Electrical Metal Items In House----When We Unplug Microwave Granite It Stops Showing Voltage ????----RICK


Grnite is SLIGHTLY conductive so if your counter top goes anywhere near live wires such as an appliance, you may sense it is hot with thaat detector. The stray field from the microwave is jumping onto the granite... HOWEVER please verify that your ground on the microwave is intact and returns to the third wire and has continuity to the case of your breaker box. If the ground is broken, that will certainly cause the indication. You can get one of those receptacle testers to test this.

ALSO NEVER trust the detector when safety is an issue. The device is "indication only" and it can be wrong for various reasons.

The power cuts off after 2 minutes of cooking. The microwave doesnt turn back on for ten minutes.


There is an automatic circuit breaker that it tripping. One of two options
1) Something in your oven is either malfunctioning (difficult to find and replace). It is likely better to just replace than pay to have it fixed.

2) The house circuit that you are using is not providing enough power to the microwave. Check if something else is connected on the same circuit. A microwave runs poorly when not getting the full 115 volts that it was designed for and may fall into a safe mode and shut down for a while.

Newer houses should have the microwave on a dedicated circuit and should not have this problem - I say should not because electricians can make mistakes too.

You can try to trip your microwave circuit and see if anything else stops working. If so, that is likely why your microwave is falling into a safe mode - it is not getting enough juice.

If you have an older home (pre 1995), try to find what else is on your microwave circuit by tripping the breaker as listed above, then not using the other appliance when using the microwave.
Good luck.

Microwave/small appliances do not turn on when plugged on to the power outlets on one wall.


What does "control panel has all fuses working" mean?

Are you saying you have an old-fashioned fuse panel in your house, instead of a modern circuit breaker panel?

If so, then I would suspect a bad connection in the panel.

If you indeed have breakers, a breaker can snap into the on and positions and still be bad.

Either problem sounds like it should be handled by a qualified electrician.

The power company or your insurance company would likely reimburse you for all or part of the electrician's bill, but you shoudl call first to be sure.

It's possible to have a faulty neutral connection in your wiring. That can lead to damage of several appliances and bulbs, and even pose a real fire or smoke hazard.

Please do not hesitate to get things fixed when you have home electrical problems!

GE Microwave Surface Lights


The control circuits for the cooktop lights and the hood fan are spearate. The problem is indeed with the control unit. It's usually caused by either the filaments shorting when the lamp blows or by removing or installing the bulbs while the oven is still plugged into the power line. We regularly repair these nationwide for $32.50.
