The dryer still runs, still heats, and still finishes — it just takes two cycles to dry what used to take one. “Takes too long” is the dryer complaint where the dryer itself is most often innocent. A dryer needs two things: heat and air moving through the drum. Slow drying almost always means one of them is short. Here are the five causes, in the order we check them, with the numbers from the manufacturers’ own instructions.
1. The lint screen is clogged — even when it looks clean
Everyone pulls the lint off. Fewer people know that detergent and fabric softener residue builds an invisible film on the screen mesh. Whirlpool-built dryer manuals say this buildup can cause longer drying times or make the dryer stop before the load is dry, and that the screen is probably clogged if lint falls off it while it is still in the dryer. The manual’s answer is to scrub the screen with a nylon brush, hot water and liquid detergent every six months, or sooner if it clogs. Fabric softener sheets should be used once, never reused. The same manual says lint inside the dryer cabinet should be removed every two years or more often, by a qualified person.
2. The vent run is too long, too bent, or crushed
This is the big one. Manufacturers publish a maximum vent length, and it is shorter than most people think. For one Whirlpool-built 29-inch dryer, the installation instructions allow a 4-inch rigid metal run of 64 feet with no turns and a box or louvered hood — and every 90-degree elbow costs roughly ten feet, down to 27 feet with four elbows. An angled hood cuts the allowance further: 58 feet straight, 21 feet with four elbows. The same instructions say a longer run will shorten the life of the dryer and increase drying times and energy use.
Plastic and foil vent are not allowed at all, and a flexible metal transition behind the dryer has to be fully extended and supported, not crushed against the wall. The manual also recommends cleaning lint out of the entire vent system at least every two years. One more line worth knowing: the manufacturer states that service calls caused by improper venting are not covered by the warranty, and are paid by the customer regardless of who installed the dryer. Many newer dryers measure this restriction themselves — see the LG d80/d90/d95 codes and the Whirlpool AF code.
3. The room is too cold or too tight
Colorado garages get cold. The troubleshooting chart in the same manuals lists a dryer located in a room below 45°F as a cause of long drying times; the dryer needs a room above that to work properly. A dryer in a closet needs ventilation openings at the top and bottom of the closet door, a minimum of one inch of airspace in front and, for most installations, about five inches behind. A tight laundry closet with a solid door starves the dryer of the air it has to pull through the drum.
4. The dryer is only getting half its heat
An electric dryer runs on two household fuses or breakers. If one trips, the drum can keep turning while the heat is gone or weak — the manuals call this out directly. One failed coil on a two-coil element, a gas burner that keeps dropping out, or a cycling thermostat that opens too early all produce warm-but-slow loads rather than no heat at all. If the dryer is not heating at all, see dryer not heating; if it will not run, dryer won’t start.
5. The problem started at the washer — or the settings
A washer that is not spinning out properly sends the dryer a load that is far wetter than it should be, and the dryer gets blamed. If the laundry is dripping when it comes out of the washer, start with washer won’t spin. On the dryer side, the manuals list the obvious ones too: an Air Only cycle selected by mistake, or a load too large and heavy to tumble freely.
Why we don’t recommend guessing parts
A new heating element will not fix a 70-foot vent, and a vent cleaning will not fix a tripped breaker. On a slow-drying call we measure airflow and heat before anything gets replaced, quote the actual repair, and the diagnostic fee is credited toward it. If the problem is the vent, we will tell you so — and whether it is a cleaning or a re-route.
Repair or replace?
Slow drying is rarely a reason to replace a dryer. Lint and venting problems cost little to fix, and elements, thermostats, igniters and gas valves are routine parts on any dryer under ten years old.

FAQ
Why does my dryer take two cycles to dry a load?
Almost always it is short on air or short on heat. The usual order is a lint screen coated with softener residue, a vent run that is too long or crushed, a room that is too cold or tight, a partial heat failure, or a load that came out of the washer too wet.
How long can a dryer vent be?
It depends on the model, so check your installation instructions. For one Whirlpool-built 29-inch dryer, the limit is 64 feet of 4-inch rigid metal with no turns and a box hood, dropping to 27 feet with four 90-degree elbows. Longer runs mean longer drying times.
Can a cold garage make my dryer slow?
Yes. Whirlpool-built dryer manuals list a room below 45 degrees F as a cause of long drying times, which matters in Colorado winters. A closet with a solid door does the same by starving the dryer of air.
My electric dryer tumbles but barely heats. What is it?
Check the breaker panel first: an electric dryer uses two breakers, and if one trips the drum can keep turning with little or no heat. If both are fine, the element, a thermostat or the controls need testing.
