The only reason to get the license is for the Contractor license.

2017-09-05 19:35:59 UTC  

I'm probably going to go with option 2. Just wanted to see if you had any relevant advice one way or the other.

2017-09-05 19:38:26 UTC  

I don't think they're blowing smoke up my ass. Construction is booming here, and they need guys who can show up sober to be management.

2017-09-05 19:46:32 UTC  

Yes it is similar here once you have over certain amount of men on a job you need to have any Master on the job.

I'm not sure if this is electrical but...we moved into a new house and the plug for the dryer is one of the older, 3-pronged ones. I switched out the cable on our dryer to fit. Now the dryer isn't drying like it used to, as in we have to run it on multiple cycles. Could this be due to the new, ungrounded cable or is it just a coincidence?

2017-09-05 21:48:58 UTC  

When you switched the four-wire cord and put the 3-wire cord you may have miss landed one of the wires. The three prong cord will attach to the ground screw which is green and the other two terminals will go on the black and red respective terminals in the dryer you were possibly running your dryer off 110 volt instead of 220. I don't know if I making any sense it's been a long day

2017-09-05 21:50:45 UTC  

Also when you go from a 4-wire to a 3-wire cord like that you will have to put a small wire jumper between the white terminal and the green screw inside the dryer the ground and the neutral go to the same place in the panel so you have to fake the dryer out into thinking it has both. So just make sure the new cord is landed on the red and black Terminals and the ground wire goes to the green screw but you put a small jumper between the Green screw and the terminal where the white wire landed in the dryer originally

2017-09-05 21:54:03 UTC  

Thanks so much. I'll have to pull it out and look at it as I read this.

2017-09-05 21:54:31 UTC  

Make sure you unplug that that 220-volt hurts

2017-09-05 21:55:05 UTC  

You either put one of the hot legs on the wrong terminal or by not putting the jumper in between the ground and the neutral the controls are not getting the neutral they need to operate as a 110-volt entity

2017-09-05 21:55:53 UTC  

I'm headed home if you have any trouble just post something and one of us will get back to you here in a few good luck

2017-09-05 22:05:25 UTC  

Thanks. What's a jumper, just a regular old wire or something specific?

2017-09-05 22:08:46 UTC  

No it's just a small piece of insulated wire you don't want it to be too small a piece of number 12 gauge wire or a piece of number 10 would be great you want to make sure it's insulated and it simply goes between those two points you jump one terminal to the other you want to make sure that the wires tightened Down Under the screw sufficiently if you have more than one wire under the screw

2017-09-05 22:09:20 UTC  

Here's what it looks like now, before doing anything.

2017-09-05 22:11:19 UTC  

I also just noticed what looks like a burned area on the black.

2017-09-05 22:11:43 UTC  

Okay I'm sorry I was thinking you were going from a 3 wire to a 4-wire cord or 4-wire to 3-wire cord. You were switching one 3-wire cord to a different 3-wire cord is that correct?

2017-09-05 22:12:12 UTC  

No, I had a 4 on there, and changed to a 3.

2017-09-05 22:13:51 UTC  

Okay the cord you have on is connected properly I did see a burn matk on one of the terminals. It's possible that you shorted out one half of your two pole breaker when you did that go to the dryer breaker in the panel turn it off and turn it back on one half of that breaker may have tripped internally when you turn it off and turn it back on it resets it do that and then run the dryer see if it gets hot if it doesn't you may have to test voltage. You can test for the 220v at the dryer receptacle and if you don't have it through the problem could lie in the breaker try resetting it first

2017-09-05 22:14:46 UTC  

What's happening is the dryer is trying to dry on half of the voltage which tells me that one half of the breaker is not operating

2017-09-05 22:15:54 UTC

2017-09-05 22:16:18 UTC  

They're connected

2017-09-05 22:17:59 UTC  

Yes that is called a 2 pole breaker it has two Hots. One half of that breaker could have went out if you touched any of the terminals together turn it off and then turn it right back on. If you have a way to test the voltage at the outlet try to test the two like slots and see if you have 220 Volt across them

2017-09-05 22:18:44 UTC  

I saw a burn mark on one of the wire terminals so I'm thinking maybe you might have bumped the wires together

2017-09-05 22:21:04 UTC  

Ok, so now it's just a matter of running it and seeing if it works better? Did I mess up the cable by bumping them?

2017-09-05 22:21:20 UTC  

I have no equipment to test it.

2017-09-05 22:22:03 UTC  

I understand okay when you accidentally touch them together you may have damaged one half of that breaker so it's only getting 110 volts instead of 220 volts. When you turned it off and turned it back on you may have reset it internally. Turn the dryer on and run it and see if it gets hot like it normally should if it does not then you were going to have to find a voltage tester and test the breaker and see if it needs to be replaced

2017-09-05 22:23:14 UTC  

To test the breaker you would take the panel off turn the breaker on and put the two test leads where the two wires on the breaker are located and see if it gives you 210 or 220 volts approximately. If not the breaker would have to be replaced. Is there anything else in your house that is not working properly is there any areas in your house that do not have power other than the dryer acting up? It's possible that you could have damaged more than one breaker. If you're not having trouble with anything else than just concentrate on the dryer

2017-09-05 22:24:33 UTC  

No problems elsewhere. For what it's worth, the prior owner was an old electrician and I think he did some work on the place, running g electric out to the barn and workshop.

2017-09-05 22:24:50 UTC  

I'll run a load and report back.

2017-09-05 22:25:51 UTC  

Okay great if it's still acting up you're going to have to find a voltage tester a Tester Lite rated at 240-volt woodwork you can probably get one for about 10 bucks. If you have to replace that breaker it is either a GE or an ite style plug-in breaker you can get it for about $9 at Home Depot and I can talk u through changing it if you need to

2017-09-05 22:26:19 UTC  

Somewhere on the panel or the panel cover it will tell you if it's a GE or an ite or Westinghouse Etc

2017-09-05 22:30:57 UTC  

Great, thanks again.

2017-09-05 22:32:16 UTC  

One last thing if you do have to have a tester if you get one from Lowe's or Home Depot their policy is to take back anything in the original package by it bring it home use it put it back in the package and return it

2017-09-05 23:05:46 UTC  

Cool. And I just remembered something that happened when I installed the cable. I, stupidly, plugged it in before connecting it just to make sure it would go in. The other, now live, end touched the metallic exhaust hose and there was a spark. I'm guessing that may have tripped the breaker. Hopefully I didn't do any further damage.

2017-09-05 23:52:37 UTC  

Hope not. 220volt is baad news. Be careful

2017-09-06 16:41:23 UTC  

@Deleted User That seemed to do the trick. Thanks!

2017-09-06 17:53:10 UTC  

No problem man anytime that's what we're here for. And for the record I do work on some appliances so if you have trouble with other things just give me a holler maybe I can help

2017-09-06 18:10:16 UTC  

Hey guys, just got my membership approved yesterday. I work as a specialist for my local dept of water and sewer. Mostly pumps and motors, but I also do some controls work and occasionally work on generators. I deal with anything from 12v up to 480v. I'll be glad to help or contribute any way I can, just give me a shout.

Great walk through @Deleted User
