Whirlpool WED4950HW0 Takes a long time to dry

[thirteenrs7]

Dryer took a long time to dry a load. Tech replaced thermostat and heater coil under warranty. Worked once. Still takes a long time to dry. 

Checked the vents for lint, as well. 

Any ideas? 

 

Thanks

Like how long is it taking? Were the element and thermostat actually bad? What thermostat was replaced? The high limit/thermal safety or the main cycling thermostat on the blower housing? 

There are a number of things that can cause a long dry complaint but the most common is typically a venting issue (airflow restriction). How long is the vent and what material? Solid duct, flex? Lots of elbows?  Is the venting crimped or smashed off behind the dryer? Is the termination hood on the outside of the residence opening up all the way and clear of lint blockage?

Can you run a load with the vent unhooked from the rear the dryer? If it dries ok with the vent unhooked then the venting is the issue. Also, check the duct chute from inside the dryer. Pull the fitter out and if you can see a build up of lint on the other side of the holes (from inside the dryer where the filter normally is) then that could be clogged up. If it still had a vent restriction and was run again, it could have worked once then stopped heating due to a blown safety limit or could be cycling on the high limit stat. 

You could also have an electrical issue with the receptacle or power or a different issue with the dryer.  Have you tried a timed dry cycle vs an auto cycle? Does one work and one doesn't? Venting is the #1 suspect but if the venting is all clear and good then you'll need another service call on the dryer. Could be a number of different things
