Question about Whirlpool Dryers
It is designed to go off and on. On normal heat setting, when the control thermostat reaches 155 degrees it shuts the heater off and the heater stays off until it drops to approx. 125 degrees then turns back on.
If it is taking too long to dry, then it is almost always lint build up in the vent system or the dryer itself.
First test should be to run the dryer with the vent hose off. If drying time becomes normal,then clean or replace the vent system. If no better.......
You gave no model number, but with the standard style, it is not uncommon for the area around the blower wheel to pack up with lint.
To clean it, you will need to remove the lint filter, and the 2 screws under it. With a screw driver, pop up the front of the top lid one side at a time, and rotate up to a vertical position.
Go to the back of the machine, and remove the backing cover.
You will see something like this.
The housing on the left covers the blower wheel and housing.
Remove the screws holding it in place, and pull away and up as far as it will go.
Check that area for excessive lint. It should be obvious. Clean as needed, and check the lint filter. If the lint filter won't clean, replace it with a new one.
There are other limit safety thermostats in that back area, but usually they simply fail, causing a no heat situation.
