Same-Day Dryer Repair in Denver Metro area

Start with Whirlpool’s own heat test: pick a heated timed cycle, run the empty dryer for 5 minutes and feel inside. If it is cold, rule out the settings first, because Air Only or Air Fluff tumbles without heat by design. Then go to the panel. An electric dryer runs on a 240 volt, 30 amp circuit fed through two breakers: one runs the motor that turns the drum, the other the heating element. If only one has tripped, the drum turns and the dryer stays cold. GE adds that a dryer can run on 120 volts and still not heat, and that a loose or burned connection where the cord meets the back of the dryer causes the same symptom.

If the power is right, the fault is a part in the heating circuit. The CPSC describes the protection layers in a typical electric dryer: a cycling (operating) thermostat in the exhaust air that switches the heat on and off, a high limit thermostat that cuts the heat if the heater box runs too hot, and a one shot thermal fuse and thermal cut-off that must be replaced once they open.

• Heating element: the coil that heats the air. If it is broken, or gets 240 volts and still does not heat, it is replaced.
• Thermal fuse: usually on the blower housing. It trips when the exhaust gets too hot, typically because the vent is clogged or the outside damper is stuck closed, and it does not reset. On many electric dryers a blown fuse stops the whole dryer.
• Cycling thermostat: keeps the drum air at roughly 150°F on Normal. When it fails, the dryer may not heat at all or may run too hot.
• A blown fuse is a symptom. If the vent that caused it stays blocked, the new fuse can trip again, so the airflow should be checked along with the part.

If the motor hums but the drum does not turn, GE points first to the drive belt, the most common reason a dryer will not spin. Try turning the empty drum by hand: with an intact belt it resists, with a broken or slipped belt it moves freely. A heavy load of wet towels or jeans can also make a belt slip. If the lights are on, nothing hums and the drum is still, the motor itself is the more likely cause.

Noise usually tells you which part is wearing. Before booking, look along the front and rear edges of the drum: Whirlpool notes that coins, pins and screws caught in that seam cause scraping.

• Squealing or squeaking: Whirlpool says the belt and pulleys wear with age; a worn idler pulley, which keeps tension on the belt, is a common source. Do not oil it, because lubricant attracts lint.
• Thumping: a frayed or damaged belt (GE), or drum support rollers with flat spots. After a dryer sits unused, Whirlpool says a light thump that fades as it runs is normal; a thump that stays can point to worn rollers.
• Scraping or metal on metal: worn drum glides or a worn felt seal at the front of the drum.
• GE suggests replacing the rollers and their axles, glides and bearings together, since a worn set makes the motor and belt work harder.

These are the first things to look at, and none of them needs tools. Unplug the dryer before you move it.

• Clean the lint screen before or after every load. If dryer sheets leave a film on it, Whirlpool says to wash it with warm water and a soft brush and let it dry.
• Pull the dryer out and look at the hose behind it: no kinks, no crushed sections, no plastic or foil. Clear lint from the hose and the wall connection.
• Go outside while the dryer runs. The vent flap should open and you should feel strong airflow. Clear lint, nests or debris, and after a Denver snowstorm check that snow is not covering the flap, as NFPA advises.
• Look for warning signs Whirlpool lists: loads warm but damp after a full cycle, a hot and humid laundry room, lint around the door seal.
• Have the duct cleaned at least once a year (NFPA), or sooner if drying takes longer than it used to.
