2) Failure in drive motor circuit.
b. Faulty rotation sensor.
c. Broken wire or connection between rotation sensor and microprocessor controller (computer) display
board.
d. Failure in rotational sensor circuit, magnet missing, or gap too large.
e. Basket (tumbler) rotation below 12 RPMS.
P. Microprocessor controller (computer) reads “Exhaust High Temp Fault”...
1. Possible overheating condition...microprocessor controller (computer) display board has sensed a temperature,
which has exceeded 225º F (107º C).
Exhaust High Temp Fault will display until the stop key has been passed. A cycle cannot be started until the
temperature is below 220º F (104º C).
Q. Dryer operates but is taking too long to dry...
1. Exhaust ductwork run is too long or is undersized...back pressure cannot exceed 0.3 inches (0.74 mb)
water column (W.C.).
2. Restriction in ductwork...check duct from the dryer ALL the way to the outdoors.
3. Low or inconsistent gas pressure (for gas models only).
4. Insufficient make-up air.
5. Poor air and gas mixture at burner - yellow or poor flame pattern...adjust gas burner air adjustment shutters
(for gas models only).
6. Lint drawer or screen is not being cleaned on a regular basis or often enough.
7. Extractors (washers) are not performing properly.
8. Sail switch is fluttering...restriction in exhaust (for gas models only).
9. Failed microprocessor controller (computer)...temperature calibration is inaccurate.
10. Failed microprocessor temperature sensor...calibration is inaccurate.
11. Failed burner hi-limit (for gas models only).
12. Failed 225º F (107º C) manual reset hi-limit (thermostat).
13. Steam damper system is not functioning properly (for steam models only)...
a. Steam damper sticking closed.
b. Leak in pneumatic system.
