My kenmore dryer take a long time to dry.But the filter is clean.

The CHECK VENT duct blockage sensing system detects and alerts you to blockages in the duct work that reduce exhaust flow from the dryer. This light does not indicate any problems with your dryer. If this light blinks, it indicates that your home's exhaust system/duct work has a serious restriction

Every time the dryer is turned on, the CHECK FILTER LIGHT WILL BLINK, as a reminder to make sure the filter is clean. Always make sure the lint filter is clean before starting a new load; a clogged lint filter will increase drying times.

The Kenmore Elite dryer has a sensor that detects poor exhaust venting, and when it does, a light flashes on the control panel. This warning light does not include a mechanism to stop gas flow, but if it is allowed to flash for an extended period, poor venting may cause the dryer to overheat. As a result, a fuse might blow and disable the gas valve or ignitor. You can prevent this by diagnosing the reason for the flashing indicator light as soon as possible.

In many cases, LINT has built up somewhere in the exhaust pipes.

Check under the lint filter. Pull it out,look inside the slot it fits in, and clear all lint from this area.

Is it possible you have used the WRONG VENT MATERIAL?
Check your vent to make sure it is 4 inch rigid or semi-rigid metal ducting. If your venting is plastic or flexible foil, replace it before using the dryer.

Check your vent hood outside. You may have a restricted or damaged vent hood. It must be clean and free of lint buildup. Check the damper and make sure it opens fully and easily and is free of lint.

I know you said you have no elbows, but I have posted the pipe run lengths with and without elbows. Keep in mind this is with 4 inch rigid or semi rigid metal ducting.

Measure the length of your exhaust system and count the elbows. Use the chart below to see if your duct is too long. If it is too long, have the duct routed to another location that is within the venting guidelines.

0~90 degree elbows=65 ft of 4 inch rigid metal duct.
1~90 degree elbow=55 ft of 4 inch rigid metal duct.
2~90 degree elbows=47 ft """"""""
3~90 degree elbows=36 ft """"""""
4~90 degree elbows=28 ft """"""""

You should always use duct tape or metal tape on all joints, NEVER USE SCREWS, as screws capture lint inside the pipe.

One more note. Lots of people overlook the fact that fabric softeners can build up on the lint filter over time. This buildup can restrict the airflow through the filter reducing dryer efficiency and lengthening drying times. After removing lint, if the filter looks dark or dirty when held up to the light, follow these steps to clean:

Use hot soapy water and a stiff brush to clean
the filter.
Make sure the filter is completely dry before
reinstalling it and using the dryer.
NEVER operate the dryer with a wet lint filter.

if the dryer seems to be running fine check the vent line and the duct that the lint filter slides into,most likely if it takes to long to dry clothes lint is blocking the air movement somewhere,when was the last time you cleaned out the dryer and vent line,you should clean the dryer once a year so you don't have a fire and your clothes will dry on time,if the vent line is long remove it from the back of the dryer and blow it out with a leaf blower,remove the lint filter duct and clean it and vac out the cabinet where the motor is.

you need to clean out the vent line and the dryer.unplug the dryer,pull out the filter,remove the bottom panel and then remove the duct that the lint filter slides into and clean it out,vac out the inside of the dryer,if you have a shop vac you can blow all the lint from the back and then vac it up,make sure you blow off the motor,alot of lint gets built up around and inside it,pull out the dryer and pull off the vent line,if it's a long run i use a leaf blower to blow out the vent line,first go outside and make sure the vent is clear so when you blow out the vent line nothing is blocking the lint from coming out.this will take care of your problem,do this once a year and your dryer will last longer,you'll need less parts changed out over the years because the dryer won't over heat,you'll save on electricity,your clothes willl dry on time and most of all you won't have any fires

Vent Frequently there's an obstruction in the vent duct from the dryer to the outside of the house. For the dryer to heat properly, the duct must be clean and clear of lint or any other substance. Heating element Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace it.hope this help you out sincerely D.Jones

when was the last time you cleaned out the dryer?there's a thermal fuse located on the top of the blower wheel housing that pops if the dryer overheats from a clogged vent line or for whatever reason the air isn't moving.unplug the dryer,if the filter is on top then the thermal fuse is in the back of dryer next to the duct that the lint filter slides into,if the filter is inside then the thermal fuse is in the front of dryer to the right of the duct that the filter slides into.unplug the dryer,with a meter read out the thermal fuse,whatever part you are reading out you have to remove at least one of the wires so you don't get a false reading.next if the vent line is a long run from the back of dryer to the outside vent i use a leaf blower to blow out the vent line,make sure the outside vent is clear before you blow out the line,any cages or screens remove them,next you need to clean out the duct that the lint filter slides into,if filter is on top don't forget to remove the two phillips screws in front of the filter on the top panel and vac out the inside of dryer where the motor is,you should do this once a year so you don't pop anymore parts,you won't have a fire and your clothes will dry on time and save electricity.let me know how you make out

you need to clean out the dryer.unplug the dryer.remove the vent line and blow it out with a leaf blower if it's a long run.make sure the outside vent is clear.next clean out the duct that the lint filter slides into and vac out the inside of dryer where the motor is.do this once a year and your clothes will dry on time,no fires and you'll change less parts if the dryer isn't running hot from blocked ducts.let me know how you make out

HI, Check the following to address this issue further.

Note: Normal drying time for a dryer is about 45 minutes (some may take up to an hour).

1. Venting
Make sure the dryer vent hose, as well as the rest of the vent duct, is not clogged.(clear the lint trap as well)

Unless regular maintenance is performed, chances are there is a lot of lint accumulated inside the dryer. This might affect the drying time and could be a fire hazard. Make sure to have your dryer cleaned regularly. Because this might involve taking most of the dryer apart, it is recommended to have a qualified appliance repairman perform this task.

2. Thermostat
There are a couple of cycling thermostats inside the dryer. If one of them breaks down, it might affect the dryer's performance. Replace the defective thermostat. These thermostats are located in the dryer vent duct and sometimes mounted on the blower assembly as well.

if dryer is filled with lint or vent line is blocked the clothes will not dry correctly,shop vac is great for this it sucks and blows,vac out what you can see and then blow out the lint from back and on motor,clean out the lint duct,where ever you pull out your lint filter either on top or inside dryer you have to clean out the duct.now go outside and check the flapper,if it isn't blowing open or hardly opening i use a leaf blower and take off the vent line from the back of dryer and blow it out,good luck

If still heating, clean out vent and check for kinks. Also, REMOVE PLUG FIRST!! Remove back and remove four screw holding filter duct assembly at bottom left. Pull duct toward rear and reach into bottom of duct and remove lint. Also, wash out filter screen.
