Strange Issue - Need Suggestions

I'm telling you if I had not seen it myself, I almost left a service call thinking that my customer had schizophrenia by the manner she described it and I gave it a preliminary look but need to go back and want suggestions.


Ceiling Fan 1 & Light 1
Switched it on and off 3 times, no juice. The 4th time, it works fine. I changed the switch, its not the switch at all, still happens.
I turn it on and off a few more times and a light in the adjacent room quickly flickers. I thought they may be connected on the same switch and the bulb may be broken but it has it's own independent switch and it's not a 3 way either. I pulled all the wires out the boxes, No observable shorts unless their in the attic space.
L-G - 120V
L-N - 120V
N-G - 0V
Nothing appears to be passing through my ground.

Light 2
While speaking with her in the kitchen. All of a sudden, I here a "clunk" like the dishwasher was going into another cycle but everything was off. The kitchen light, not all of them, just one, dimmed really low then went back to normal. Why only this light? The kitchen was just redone so there may be an issue in the attic.

Light 3 Living Room
Same thing as the ceiling fan. Turn it off and on nothing. Leave it for a minute and it randomly turns on and randomly turns off.

Buzzing Noise
Customer complains over and over of a buzzing noise in the attic. I checked several times and heard nothing. Then when I was leaving by the door I hear a strange humming noise but almost impossible to identify where its coming from. She tells me she cut the wire to the doorbell and they plastered over it. I checked the line, its dead. It sounds like a washing machine running in the distance but it was off.


At first, I thought the lady was crazy. I really did, but I see the issues now myself. Anyone have any ideas or suggestions? The issue seems to be across the house globally for the last year after she had her kitchen redone. What would cause such a systemic issue throughout the home?
 
The only way would be to go through it one by one or just replace wiring, correct? What would be the most efficient way to go through this mess.

Start at the service. Main panel. Meter base. POCO connections.

Check voltages at the main breaker / fuses.

If the problem is throughout the house start at the main checking connections.

Find ways to break things down in halves. Turn off half the breakers. Find what might be the midway point in the room and open that box up, stuff like that. Divide, isolate, test, repeat.

Also, when checking weird problems putting a heavy load on a circuit can help track down a loose connection or a bad device. If everything is testing ok but there is still a problem plug in a heat gun and test voltage again.

As you were writing that the strangest thing she said just hit me. She kept saying she noticed the problems more when she pulled into the home and when her car was out front. This is what made me think she is nuts at first. Whats her car outside got to do with anything. I remember a couple fixtures outside the home where that room is, missing the fixture itself with wires hanging and a separate motion detector out there. I may be grasping at straws but I wonder if that motion detector is causing it when it detects motion. I do appreciate that advice and will certainly try it.

I really want to solve this one.
 
MOre data needed:
1. underground or overhead service?
2. what brand/style breaker panel
3. type of lamps that flickered - incandescent, fluorescent, LED? On dimmers?
4. Fan1 and Lt 1, does it always work on the 4th try or is it random - you imply it is always the 4th try it works?
5. re: randomly turns on and off - what is approximate timing cycle, how long off and how long on? Or did it just happen once or twice in a half hour?

Already mentioned is to break it down by progressive breaker turn off.


If you had posted this 6 days ago, would have thought it was a Halloween joke aka April Fools.

UNDERGROUND
2. what brand/style breaker panel
200A MAIN - SQUARE D
HOMELINE

3. type of lamps that flickered - incandescent, fluorescent, LED? On dimmers?
FLUORESCENT AND LED BOTH

4. Fan1 and Lt 1, does it always work on the 4th try or is it random - you imply it is always the 4th try it works?
Random. At one point it worked every time for 10 - 15 switches, then missed 6 times, then worked. It's very odd and random. The other light is also intermittent. Nothing changed in the home so to draw understand the causation is tough.

5. re: randomly turns on and off - what is approximate timing cycle, how long off and how long on? Or did it just happen once or twice in a half hour?
in about 35 min it happened twice. The homeowner yells for me to come over "come here, see...see, I'm not crazy" and I saw it happen. Then 20 min later we were talking and it did it again. Also a fan on the other side of the home slowed down and I ran a voltage check on it, saw nothing.
 
How many circuits are you dealing with that causes all these problems? If it all on the same circuit that could help narrow it down a bit.

Trun off breakers until the kitchen light in question goes off and then see if this is the circuit feeding the other problems.

If it's only one circuit you can trace the circuit until you find the problem.
 
I think the answer is obvious.

Clearly, you are both crazy! :lol::lol:

When a new problem arises, my first question is, "what recently changed?" She said this started after the kitchen remodel. I would ask for details of what that remodel entailed. Were new outlets added to serve the countertops? Were new overhead or under cabinet lights installed? Was a new island (with its receptacle) installed? Are the fans new?

Can you get a copy of the electrical permit? It might give you a better answer to the "what recently changed" question.

 
The buzzing might be the doorbell transformer. Did someone cut the line from the transformer to the doorbell, or did they actually cut the power to the doorbell transformer?

Edit: Now I see where the kitchen was redone. I agree with the above 100%.

You think there was a permit. The owner would have called the original EC. I am sure there is something in the attic or buried in the wall.

It would be nice to know if the job was permitted. But a kitchen remodel normally doesn't call for a set of electrical drawing. If you are lucky a permit may state the number of fixtures and receptacles installed. Around herre on a kitchen remodel you wouldn't even get that information from a permit. You may furnish that information on the permit application but it won't be on the permit issued.
