My whirlpool duet electric dryer needs several

Initial reaction is yes, probably.

Second guess would be the switch.

The switch tells the dryer what to do, and if the heating element is good, it will do it.

Test the switch quickly first, and if it checks out, look at the element.

Venting issues cause 99.9% of long dry times (and also cause water in dryer).

Clean venting, or replace if it's plastic or aluminum foil.

if its hot,the element is probably ok,seeing how old it is ,and im assuming its worked well for you,the first thing i would do is un plug it pull it out from its spot and clean it ,check vent for lint buildup,remove back of dryer,fan and dryer lint holder areas get built up with lint paper and whater ,was left in your pockets,make sure the are clean,element then can also be tested with continuity setting on volt meter,most of the time you can see the damage in the element without a meter,if you have never taken a dryer apart before,i reccomend finding a friend with some mechanical skills to help,be carefull ,always unplug it first,hope this helps,aloha from maui todd0708
