No power to unit, specific wire identified... help?!
I have a frigidair HE front loading washer and dryer pair.
In the past, I had an issue with the dryer drum (no heat) randomly staying on unless unplugged before it completely lost power and refused to light up. I ended up unable to figure out the problem and called in an appliance repair person. Too much money later, and I was told it was simply a loose connection he fixed and no more issues.
I am once again in this position. A few months ago it was running (no heat) without stopping... and I had to physically unplug it and slam the door of all things, to restore it working properly. (I slammed the door out of anger, and low and behold... fine. I feel like I jiggled something back into place.)
I have power to my outlet. I have power in the 3 prong power cable. Confirmed with a little voltage sensor that simply blinks and beeps continiously if there is power, and one beep and solid light if there is not power. The outlet is functional and plugged in.
I opened up the top of the unit. While plugged in it seems one of my wires is bad. I can't figure out why because all the connections seem good.
This photo shows the "inside" where my 3 prong dryer cable attaches. These cables come from behind the 3 power connections. I hope it will help identify the issue.
There are 3 wires. Black, Red, and 2 white that sprout from the same hole. One white swings back and attaches to nothing, and I'm not the best "electrician" but I assume this a is ground wire of some kind. The other white wire runs along towards the front of the unit and then splits into two, one running to the control panel, one running into a spot by the drum.
The red and black wires have power. But the white wire that runs to the control panel and drum, has no power along it's entire length. No power at source, no power anywhere along the line.
I don't think a ground wire would run and be connected to the control panels, but I will be quite embarassed if that is the case and why there is no power.
I can't find damage. I can't find issues. I am hoping someone has dealt with this problem or can tell me where I should look for a disconnect or what the exact issue is.
I went ahead and installed a new dryer power cord and it has resolved the issue.
I guess part of the cord was shot, because I uninstalled and reinstalled the old one and still had issues, it wasn't until I put the new on in place that everything seemed to work again.
You may still have a problem with the wiring if this is a 3 wire hookup.
Here is the wiring diagram for this unit.
Here is the install sheet
In a 3 wire hook up the Neutral (white) and the earth ground are the same wire.
So if the machine frame is not connected and a live wire (black or red) should short to the frame the frame becomes live. Touch it and a ground and you will get a shock.
This does not apply to a 4 wire hook up as Neutral and earth ground (green) are separate. so the green goes to the frame and the Neutral is not connected to the frame.
I would check that it is wired correctly.
Considering it was only serviced once by a professional for a loose connection. And after that had the error codes run once, by me in the past, before cleaning stuck buttons... it's pretty safe to say it's in factory (correct) wired condition with one owner.
I just wanted to be sure it was OK as you had said one wire was attached to nothing and I really could not see much looking at the diagram.
