First, you must know that a common clothes dryer is really a water pump. It pumps water outside by
heat convection. Just because its hot doesn't mean its drying clothes efficiently.
The tip here concerns the filter. If you think your filter is clean, look again. You may have cleaned
all lint from it but it probably is still ineffective and energy draining.
Do this. Place your filter under a trickle of water in the sink, after lint removal as you usually do.
The water, most likely, will not go through the filter. What happens is that water promotes scale and clogs
the filter. (well you've got water being dried by heat which leaves scale.) This scale (or stopped up filter)
can cause a great deal of extra running time, and a dryer uses a lot of energy. (Electricity)
Scrub the filter with a bristle brush and dishwashing liquid and then run water on the filter again.
You can see how much more the water runs freely through the dryer filter.
Dry the filter, and reinstall. It's so nice to save a great deal of electricity!
You can see how the wet air is not moving the water out of your clothes very efficiently and it also
can cause the dryer to overheat too much so that the thermal switch (or fuse) blows thus causing a
expensive service call. (Most won't even tell you about the scale clogged filter anyway) Because most
don't know it either.
Enjoy your savings!!!!
