My whirlpool AWZ510E washer dryer - the dryer doesn't seem to be working - it goes through the cycle but the clothes are still as wet as before. I am using the same cycle as I always have which used to work.

There are 3 reasons for a dryer not doing the job yet running through the motions. 1st, the heat is not being produced and only cool room temp air is circulating. this can be a burned-out electric element or an over-heat sensor, or in0line safety fuse. ( if gas, can be ignitor or gas valve coils).. It could be that the washer is not ringing (spinning) dry the clothes verywell and there is too much moisture stiil in clothes which would double the dry time from 50-60 minutes to 2 hours. 3rd, could be clogged vent line and the hot moist air cannot leave the dryer so the clothes get hot by the moisture stays.

Most likely the venting is restricted or fully clogged. We clean dryer vents professionally and have seen it over 10,000 times. Call a local dryer vent cleaning specialist if you can't do it your self.
