TrickleStar® DryerSaver®

I think I'll stick with the tried and true method of feeling my clothes to see if they're dry. They can lay on my bed for awhile if they're almost dry. $150 buys a lot of my time now that I'm retired.

The dryer my parents bought 53 years ago had a sensor.

BTW, it also had a lint filter in the door. The newer ones I know about have it on the top. Why the change?

Probably cheaper to manufacture.

Mine has it at the front; not in the door but in the vicinity:

I'm sorry it's taken me a day to reply. I had to consult with my Lint Filter Director.

Are they the same brands? Sometimes designers see some advantage in one design or another, and sometimes they just want to be different to say they have an advantage.

Both my mother's dryer and mine have the filter in the top, right rear.

My mother's was a Whirlpool and mine is a Sears Kenmore made by Whirlpool.

My mother bought hers in 1957. It was pink, and I think the lint filter was 5 or 6" wide and 12 or 14" long. No dryness sensor.

Mine was bought by the previous owner, in 1979, it is white, and I think the lint filter was 5 or 6" wide, just like my mother's but twice as long. I just keep pulling and pulling and more comes out. Maybe that makes it bigger than one in the door. It's curved. The filter door looks the same as hers.

The kind of clothes has a big effect on how much lint there is.

I sure hope I can remember how to reassemble the dryer, which has been apart for maybe 2 years.

Three dryers in three houses in 56 years. All had a sensor and the filter is in front of the drum. Neither of the places you mentioned. Different engineers, different ideas.

Can't imagine may dryers out there without a sensor in the past 20 years or so.

They always have a simple model, either for poor people or to make buyers feel special when they spring for the fancier model. I'm not sure which category has more customers.

Also for landlords, and for laundry rooms in low cost apartment buildings.
