P. Dryer stops during a cycle, microprocessor controller (computer) buzzer (tone) sounds for a
few seconds, and then microprocessor controller (computer) L.E.D. (light emitting diode)
returns to “FILL”...
1. Loose connection somewhere in the main power circuit to the microprocessor controller (computer).
Q. Microprocessor controller (computer) L.E.D. display reads “SEFL”...
1. Rotational sensor circuit failure...fault somewhere in the tumbler (basket) rotation or circuit ...
a. Tumbler (basket) is not rotating ...
1) Broken tumbler (basket) drive chains.
2) Failure in drive motor circuit...refer to Section B, Section C, and Section D on page 63.
b. Faulty rotation sensor.
c. Broken wire or connection between rotation sensor and microprocessor controller (computer).
d. Magnet missing or gap too large.
R. Microprocessor controller (computer) L.E.D. 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
microprocessor controller (computer ) is manually reset by pressing the “CLEAR/STOP” key.
S. No heat (for Steam Models ONLY)...both microprocessor controller (computer) L.E.D. heat
indicator dot and the “HEAT” relay output L.E.D. are on...
1. Fault in 225º F (107º C) hi-heat (limit) switch circuit or thermostat.
2. No (external) compressed air to steam damper...80 PSI (5.51 bars) required.
3. Failed steam damper 24 VAC pneumatic solenoid valve.
4. Failed steam damper pistons.
5. Steam damper stuck closed.
T. Dryer operates but is taking too long to dry...
1. Exhaust duct work run is too long or is undersized...back pressure cannot exceed 0.3 inches water column
(W.C.) - 0.74 mb.
2. Restriction in duct work...check duct from the dryer ALL the way to the outdoors.
