2. Rotational sensor circuit failure...fault somewhere in the tumbler (basket) rotation or circuit...
a. Tumbler (basket)
is not rotating...
1) Broken tumbler (basket) drive V-belt(s).
2) Failure in drive motor circuit...refer to Section B, Section C, and Section D on page 42 and
page 43.
b. Faulty rotation sensor.
c. Broken wire or connection between rotation sensor and microprocessor controller (computer).
S. Microprocessor controller (computer) L.E.D. (light emitting diode) display reads "Hot"...
1. Possible overheating condition...microprocessor controller (computer) has sensed a temperature which
has exceeded 220º F (104º C).
"Hot" display will not clear until temperature sensed has dropped to 220º F (104º C) or lower and the micro
processor controller (computer) is manually reset by pressing the "CLEAR/STOP" key.
T. Gas heating unit is not operating (no heat)...no spark at burner area when the dryers is first
started, and both the heat indicator dot and the "HEAT" relay output L.E.D. (light emitting diode)
are on...
