Dryers installation: the cord is the install.
No dryer ships with a power cord — new, open box or surplus — because the cord depends on the outlet in your wall. Nine of ten dryers that "don't work" on day one are a cord wired to the wrong terminals, a ground strap left on or taken off wrong, or one leg of the 240V outlet dead. The connection is a ten-minute job for a person who has done it and a service call for one who has not; both are fine, and the manual's wiring page is the authority.
First use: what is normal
A new machine can do things on its first run that look like a fault and are not. Here is what the makers say is normal, what to do first, and where the line is.
Normal the first time
- An oily, burning or new-plastic smell for the first few loads. It fades with use.
- A short squeak at start-up that goes away in seconds.
- On a gas dryer, a click and a buzz when the valve opens and a low roar from the flame.
- On a heat-pump dryer, a hum from time to time.
Do this first
- 1Run it empty for 20 minutes to clear the new smell, with the door or a window open afterward.
- 2A heat-pump dryer holds coolant: let it rest for 2 hours before the first use, and empty its water container after each load unless it has a drain.
Where the line is. A burning smell that stays, a thumping sound, or a squeak that starts once it heats up is not normal: stop using it and text us.
What is typically not in the box
Surplus inventory — open box, cancelled order, overstock, minor scratch & dent — is priced for exactly this: a unit can arrive without the small items that ship with a sealed machine. Have these on hand before install day.
The power cord — a 30-amp 3-wire (NEMA 10-30) or 4-wire (NEMA 14-30) dryer cord KIT. Buy the kit: it comes with the strain relief and new terminal-block screws, so a missing or stripped screw on the block is not a stop.
The vent kit — 4-inch rigid or semi-rigid metal duct, two clamps, the wall hood if there is none.
A gas dryer's flexible connector and shutoff valve, where the house has none.
The lint screen on an open-box unit, occasionally — check it is in the slot.
The printed manual — download it by model number.
Power, water, gas, venting, space
What the room has to have before the appliance comes through the door. The manual gives the exact figures for your model; these are the shapes to check.
A dedicated 240V, 30-amp circuit with its own receptacle: a 4-prong NEMA 14-30R in any home wired or remodeled since 1996, or an older 3-prong NEMA 10-30R where that existing circuit remains. The cord must match the outlet, and the dryer's terminal block is wired to match the cord.
A gas dryer plugs into a grounded 120V outlet; the heat is gas. A 1/2-inch gas line with a shutoff valve in the same room, connected with a new listed flexible connector by a licensed installer.
Rigid or semi-rigid metal duct, 4 inches, as short and straight as the room allows — most makers cap the run at about 35 feet of equivalent length, with every 90° elbow counting about 5 feet. No foil or vinyl, no screws into the duct. A ventless (condensing or heat-pump) dryer needs none.
A dryer needs the manual's clearance at the back for the duct's bend, and a closet needs its ventilation openings; a dryer starved for air runs long and hot.
Level on four feet. A stacked pair needs the maker's stacking kit, which is a separate part.
The install, step by step
An overview of the manufacturer's own sequence, so you know what a good install looks like whether you watch one or do one. The manual's page for your model is the authority on every figure.
- 1
Match the cord to the outlet
Count the slots on the wall outlet: three slots is a 10-30 (3-wire cord), four is a 14-30 (4-wire cord). Buy that cord kit. Never change the plug on a cord to fit, and never replace a 4-prong outlet with a 3-prong.
- 2
Open the terminal block cover
On the back, lower corner, behind a small plate. Three screws on the block: the middle is neutral (N), the outer two are the hot legs (L1, L2). A green screw or the frame nearby is the ground point.
- 3
Wire a 4-wire cord (14-30)
Red and black to the two outer terminals, white to the middle neutral, and the green wire to the green ground screw on the frame. REMOVE the bonding strap that ties the neutral terminal to the frame (or move it per the manual) — with a 4-wire cord the neutral and the ground must be separate.
- 4
Wire a 3-wire cord (10-30)
Outer wires to the two outer terminals, the middle wire to the neutral terminal, and the bonding strap stays in place, connecting the neutral terminal to the dryer's frame — that strap is what grounds the cabinet on a 3-wire circuit. Fit the strain relief where the cord enters.
- 5
Close it up, set the vent, level
Cover back on, duct clamped to the dryer and to the wall, no sags, then level the four feet. Push the dryer in without crushing the duct.
- 6
Run a timed-dry cycle
Plug in and run Timed Dry for ten minutes with the door closed. Heat inside, air at the wall hood outside, and no new smell is a finished install. A gas dryer: the installer leak-checks the connector with the dryer running.

Mistakes that look like a broken machine
Most first-week calls are one of these. Each is an install item, not a fault — and each is the reason we ask for every function to be tested before the installer leaves.
The cord wires on the wrong terminals — a hot leg on the neutral post trips the breaker or leaves the dryer dead with the drum turning.
A 4-wire cord with the bonding strap left ON — the cabinet is tied to the neutral, which the code forbids; a 3-wire cord with the strap taken OFF — the cabinet is not grounded at all.
A terminal screw missing or a wire not under the screw — the dryer runs with no heat, or heats on one cycle and not the next. The cord kit's new screws fix this.
One leg of the 240V outlet dead — the drum turns, nothing heats. Reset the breaker fully off and on; a dead leg at the outlet is an electrician's call.
A crushed or foil vent — the dryer runs long, the airflow code lights, clothes come out damp.
When a licensed installer is the standard
We recommend professional installation for every appliance we sell. On a dryer these are the parts of the job that the code, the permit or the manufacturer's warranty place with a licensed trade.
A new 240V receptacle, a 3-prong-to-4-prong conversion or any breaker-panel work is a licensed electrician's job under the National Electrical Code.
A gas dryer's connection, shutoff and leak check is a licensed gas fitter's or plumber's job under the fuel-gas code.
A vent run through a wall, a roof or a long chase, or a booster fan, is an installer's job — the duct rules are inspected code items.
Asked at the counter
Why doesn't the dryer come with a cord?
Because the cord depends on your outlet — 3-prong or 4-prong — and the manufacturer cannot know which. No dryer, new or surplus, ships with one; it is sold as a kit beside the dryer.
My outlet has three slots. Can I use a 4-wire cord?
No — the cord must match the outlet. A 3-slot outlet takes a 3-wire cord with the bonding strap left in place. If you would rather have the newer 4-wire setup, an electrician replaces the receptacle and the circuit's wiring, not just the plug.
The terminal screws were missing on my unit. Now what?
Buy the cord KIT rather than the bare cord — it includes new terminal screws and the strain relief. Screws and small hardware are among the items a surplus unit can arrive without, and the kit covers it.
The drum turns but there's no heat.
One leg of the 240V supply is missing: a tripped breaker, a wire off a terminal, or a dead leg at the outlet. Check the cord's three connections under the cover first, then the breaker, then call an electrician for the outlet.
Can I run the vent with the flexible foil duct?
Not inside the wall, and most makers say not at all — foil and vinyl kink, trap lint and are a fire path. Use rigid or semi-rigid metal; the dryer-vent guide has the length and elbow rules.
What your receipt says about installation
Installation & testing
Apex Sales does not perform installation, and we strongly recommend professional installation. Moving or installing an appliance without the proper steps — transported upright and secured, every connection checked, and the unit leveled — can loosen parts or cause problems, and improper installation can void the manufacturer warranty. Have a licensed plumber, electrician, or appliance installer test every function of the unit before they leave, so any issue can be reported right away. Damage caused by improper installation is not covered.
Condition & warranty
All units are surplus inventory (open box, cancelled order, customer return, overstock, or minor scratch & dent). Every unit includes the manufacturer's full factory warranty. Please inspect thoroughly in person before purchasing — cosmetic imperfections or missing accessories are possible.
These pages are a general reference for the appliances we sell. They do not replace the manufacturer's installation instructions, the local building, electrical, plumbing, gas and mechanical codes, or the judgment of a licensed installer. Apex Sales does not perform installations and is not responsible for installation performed by the customer or by a third party. Damage caused by improper installation, transport or connection is not covered by the manufacturer's warranty or by Apex Sales.
When it's not a DIY moment
Everything on these pages is safe to look at with the machine unplugged or the gas shut off. These three are not a look — secure the appliance and call.
Gas smell
Close the appliance's shutoff valve if you can reach it safely, open a window, leave the room, and call the gas utility from outside. No switches, no flames.
Burnt smell, a melted plug, arcing
Shut the breaker off, not just the appliance. A scorched cord, plug or outlet means an electrician looks before anything is plugged back in.
Water that will not stop
Close the supply valve at the appliance first (washer, dishwasher, fridge line, water heater cold inlet), then unplug. Mop before you diagnose.
Text us the model number and what it's doing — we'll point you at the next step.
A fix, a part, or a warranty call — the plate's model and serial plus one line about the symptom is all it takes to tell which.
These pages are educational. Every appliance is a little different — follow the manufacturer's manual and local code, and leave gas, water heater and 240V work to a licensed installer.
