Is it really the motor, Part 3?

Thanks again JP! I sure wish I had 1% of your knowledge about these things! Actually he never did mention any bearings. But he did have the tub clear off when he hit the start switch and got that awful noise. He demo'd it a couple times to me and gave me the thing about the 2 windings in the motor and the inner one being discolored, etc. After he had left, I did wonder if something could have been caught in that little fan, because this happened to me not long ago with my fridge. My cats managed to cuff stuff up in there and I got this horrid clatter noise. Figured that one out for myself! But I did not SEE anything in the dryer fan and was actually surprised (as was he) that the innards of the dryer were so clean, because at my house, there is cat hair in EVERYTHING. I have many cats and their bedding makes up most of my laundry. I do recall him explaining what you just said about getting the noise at startup, and then the whole thing cuts out to cool off, and it keeps doing that... but that's not it. It was drying the clothes fine.

Anyway, I got the other dryer from him (sure do miss the old one though, with the light inside and the door that opened DOWN). Already having a problem with THIS ONE! Was just trying to research on the web... it must be the sensor?? The clothes do not get dry when I use the automatic cycle, even though I set it for the 'most dry' setting. (In fact, I have not even tried the timed cycles yet.) This dryer I got is a "perfect match" (he said) to my washer, about 3 to 4 years old, GE Profile Prodigy Mod. DPSR405EA1WW. The little red light goes on when you use the automatic cycles, when the sensor is supposedly working. Just came across something that said maybe the sensor or sensors are just dirty from fabric softener or lint, was going to check to see if I can tell anything just looking in the drum. But probably I should have him put a new sensor in, don't you think, since I just got it and it is "guaranteed" and should work just fine? I think he would be ok with replacing it. Is this a common problem (having the sensor go bad)?? You sure know your stuff! You must be a professional at this, yes??
