Dryer not functioning properly
We recently moved out a non-working dryer an replaced it with a friend's. I had to change the pigtail on it (four prong to a three prong).

Now the dryer isn't well... Drying. We are having to run it twice to dry the clothes.

I have checked the vent, all clear. We have also vacuumed out the area you can reach through the lint trap. No change.

So... What do I check next?

Is the heating element working? With the power OFF, you can disconnect it, and check it with an ohmmeter. I would also check the voltage, to make sure that you don't have a drop someplace. The first thing that I would probably check though, particularly since you have encountered the same problem with two dryers, is whether the problem is with the dryer or the washing machine; if the washing machine is not spinning the water out as it should, the dryer has to work twice as hard. Sometimes you won't pick up on this at first pass, but laundry that is wetter than you remember it when you remove it from the washing machine or water remaining in the bottom of the tub can provide telltale signs.

I'm pretty sure it's not the coil, I have had that problem before.
It worked perfectly and then after moving it it's not. I was curious mostly if it was me changing the plug.

I'm guessing it does heat? So if it heats you probably hooked the supply cord up correctly. Its kinda hard to hook it wrong if you remember that the middle prong of the cord always goes on the middle lug of the dryer terminal block. Now, not that it will matter on the drying part but did you reattach the ground strap that was original on the dryer terminal block?
How long is the vent run?

The vent run is less than six inches from dryer to hole, and it's an exterior wall so it goes directly outdoors.

I was just told the dryer seems to be not running as long of a cycle than it did before.

What was wrong with the old dryer?

Do you have 240 volts between both hot legs on the recepticle?

If you have a kitchen thermometer, stick it in the dryer vent and check the temperature. You can tell pretty quickly if it's heating properly by that method. You are wanting it to cycle between 125 and 160F.

Just out of curiosity... how long of a run is your dryer vent tubing?

Three prong will be two hots and a ground.

Four will have two hots, neutral and ground.

Red/Black is hot. White is neutral. Ground is green. Get a meter and stab the two prongs on the outlet. Should have 240V. Each should be 120 to the ground prong.

Same with the cord. Should have 240v Between the hots and 120v each to ground.

Its possible you wired it 120V. It will give you function, but elements will only work at 1/4 of the rated heat. Clothes will take much longer to dry. (basically just tumble drying at that point)
