    Our gas dryer died... was given an almost new washer and dryer from a dear friend.  Could not replace ours on our own at this time.  This was the best way for us to go.  After raising 7 children there are only the two of us.  We will be careful on the use of electric dryer.  We know the difference..grateful for the new dryer.  Just answering...Thanks for your help.  We were almost there.  You finished the job for us.  We had TOO much help......

You will typically need a 40 amp 220V circuit for this ( check with local building inspectors).  You will need to run some hefty wire probably #8 three wire  (again check) and install the type of plug receptacle that is on the  dryer cord.

Inside the breaker box you will need a dual breaker 220V breaker rated at 40 amps.  The wire coming into the breaker box will need to be clamped in place with appropriately sized wire cable clamp where the enter the box through a knockout- available at any hardware store.


Now the big question-  why are you switching to electrical?  Gas is pretty much half as expensive as electricy  and will dry the clothes faster (usually gas dryers generate more heat than electrical ones).   Just wondering..

    Good luck with your new dryer.  I mentioned #8 3wire ;  I believe that #8 3 wire *plus ground* would be appropriate and you would attach the bare ground wire to the grounding lug in the dryer  recepticle on the wall.  The ground wire in the breaker box gets attached to the grounding barr (which may or may not be connected to the neutral bar- depending if this breaker box is a main or a subpanel.


    Enjoy your empty nest!  :)

Trips circuit breaker.

Depends on whether electric or gas dryer. Electric dryer is a fault in the dryer or serious electrical issue on the circuit. Gas dryer means too much overall load on the circuit from all items on it or high demand when the dryer drum motor first starts. If the latter and IF the wire gauge supports it, a simple upgrade to a higher amperage breaker may fix the problem. 20 amp breakers require a minimum 12 gauge wire on all parts of the circuit to which the breaker is connected. 12 gauge wire is about 2 mm or 13/16 inch in diameter.

I’m happy to help further over the phone at

I have a new Husky Model C801H air compressor 230 Amp, how do hook up the wiring

I'm assuming you mean it's 230 volts, not 230 amps. (big difference here)..and I think it's actually 240 volts. (minor detail)

This is really a job best left to a qualified electrician, as you're going to need to have a 30-amp outlet installed (compare to an electric clothes dryer outlet, or a welder outlet).

The cord supplied with the compressor should be a 4-wire cord,consisting of 1 black, 1 white, 1 red and 1 green wire.

The green wire is the ground and it absolutely *must* be hooked up to guard against an electrocution hazard. Of the other 3 wires, the black is 1 or the 2 hot leads (the red is the other hot lead). The white wire is the neutral.

You will need a *TWO-POLE* 30-amp circuit breaker of the type that's made for your specific make & model of electrical panel. This breaker will have two separate, independent bussbar connections on the underside and 2 separate screw lugs to attach your Black & Red wires to (individually, not to the same lug). These are unique as to brand and model, so you will need the right one. If this is going in your home garage and you're lucky enough that your breaker box is there in the garage where the compressor is going, then it's going to be much easier. (much less expensive) Still I am going to stop here as I cannot recommend anyone working inside their electrical distribution panel unless they are a qualified electrician. Please hire an electrician to hook this up for you. Please do not attempt to hook it up yourself.

I believe you dryer is not hooked up correctly electrically.
You will need to unplug it from the wall without touching it.
You may need to use a wooden broom handle or some other insulating items to accomplish this.
Remember, electricity cannot flow through dry rubber, paper, cardboard, or wood.
If you cannot move the dryer away from the plug so you can reach it, you will need to shut off the dryer at the breaker box or fuse box before you start to unhook it.
The breaker box or fuse box should be marked on the paper on the back of the door as to which 2 circuit breakers or fuses are for the dryer, but most are not.
You should get someone smart to fix this before you have a fire or someone killed .
Be blessed.

Hoover 0910dryer not heating. element replaced not long ago

Hi, the possible causes are: Possible Causes: The wall receptacle, power cord (plug) and electrical supply must be in good condition and wired correctly for the dryer to heat.
  • Supply Issue - Loose or missing connection on supply wire from circuit breaker.
  • Plug Issue - Loose or missing connection in the wall. Defective, worn or damaged wall plug.
  • Cord Issue - Loose, missing or incorrect connection of the power cord to the dryer terminals.
If gas dryer and does not heat, Gas Dryer heats with a gas burner, make sure the gas supply line valve is open.
Also, for electric dryer,
Electric dryers require two 30 amp breakers or fuses in the house electrical box to run and heat. If one breaker is tripped or one fuse is blown, the motor, the timer and lights can work but the dryer will not heat.

Dryer runs good noheat

Electric or gas? Electric maybe the the dual beaker didn't pop both sides. On Electric 220 v, 115 to the motor and controls 115 to the heating elements. Check the house breaker box see if breaker is tripped. On gas could be many things. Starter, thermal coupler, clogged pilot, ect.

Wiring an electric dryer

If you are referring to the breaker / fuse box to the dryer recepticle, you would use 10-3 NM w/ ground. (that is 4 conductor wire: 2 "hot", one neutral, and one ground.) If you are referring to the dryer to the recepticle, use a pre-made dryer cord, either a 3 wire or 4 wire, depending on which recepticle your home has.

Just hooked up outlet. Dryer tumbles, wont heat. Have I wired the outlet wrong?

Hi, Did you put red and black wire to the outer posts? White wire ti center and green to ground screw on cabinet? Dry will run on 120V but needs 240V for heat. Make sure there is 240V to the outlet as well.
Hope this helps. If so, please feel free to rate my answer so that I know how I am doing.
