Testing a "working" dryer

When picking up a washer & dryer set, several times the people say the washer is toast, but the dryer still works. So how do you test it without unhooking your dryer and moving it out of the way? Here is something you might try. I have several I needed to test, so I built my own "extension" cord. I went to home depot and purchased a single gang box and a 3 prong 220 outlet (like what is in the wall of your utility room). I took a good 3 prong cord I had kept from a dryer I had scrapped, cut the brass fittings from the ends. I split the plastic covering of the cord about a foot to get some pliability, and inserted them through the holes of the gang box. After stripping about an inch of insulation from the end of the cord I inserted the wires into the holds of the outlet and tightened the screws down. After that was done I screwed the outlet onto the gang box and viola, I have my own extension cord. Tried it on one of my dryers I needed to test (unplugged my dryer and plugged in the extension cord without having to move my dryer), and it worked like a charm. Do not have pictures yet but will try to get some uploaded.

Your correct, which is why I use 2 vacuum cords (they are long enough to reach a 2nd circuit). You can't plug 1 into the top outlet and one in the bottom outlet. Usually I don't have a problem finding 2 close circuits. Personally it works well because I have 2 circuits in my garage. If I am elsewhere, I would usually run one to the garage and one inside. Usually they will be separate. It's not perfect because of the problem you described, but it gives me a lot of flexibility.

The house I lived in TN had a bedroom 220 AC I removed, and later needed a 220 out front, so I pulled the wire from that AC plug under the house and out the front, and put an AC plug out there for testing 220v ACs. The porch was up off the ground, so when I was done I'd roll it up, and stick it under the porch out of sight, and turn off the breaker to it at the box. The romex rolled up easily without harming it, just using the same pattern it already had in it since coming off the spool

When I started building my trailer, I bought a 220v welder at harbor freight, and swapped out plugs on the 220v line to fit the welder

Just make sure they work and heat. LOL

Alot of them go to the curb because someone usually didn't bother to keep the ductwork clean and blew the thermostat. Usually a simple check with an ohm meter, and $10 to $15 in parts unless you scrounge one from a donor.

I connected 1 cord to the first 220 leg, then a second cord to the next 220 leg. I plug 1 vacuum cord in a regular 110 socket, plug the other vaccum cord in another 110 socket and have 220 when needed. It also has been valuable if I am away from the house and need 220 for something. If I need to weld something at a friend's home, I just take my home made 220 extension cord. No need to unplug my dryer, install a new breaker and run a 220 outlet, it's completely safe, and it all cost me about 5.00.

Is there any way you can post pics of your method? And what happens if only one of the two ciruit breakers trips? Would that burn up your 220v appliance? Also, wouldn't using a bigger extension cord be better, like one from a floor buffer or burnisher, which uses minimum 12/3 AWG. I serviced vacuums and floor buffers for years, the largest cords I saw on vacuums were 14/3.

Gee, I'm glad we only have 240V AC & 'Three phase' here in NZ...

That is why I like my extension cord made out of a dryer cord. I can leave it plugged in long enough to make sure the dryer heats up properly without having to worry about the cord heating up too much. Plus I can test the dryer just outside the utility room door on the porch, and when the dust blows out of the vent hole it will blow on the porch, not in my utility room.
