Kenmore series 90 dryer, does not get hot enough.
Heating element is on for one min, and off for two minutes, does that sound right ?
Electronic sensor for dampness does not read to ground, even thou cloths are damp from washer. Suggestions??

Diagnostic Guide Link
I found service tech diagnostic guides (PDF format) during an online search. This includes instructions on putting the dryer into test mode in order to check switches, etc. Here are the links:
