e. Failed electric elements. f. Sail switch is fluttering.

1.) Restriction in exhaust.

2.) Switch not adjusted properly.

9.Extractors (washers) not functioning properly.

10.Failed microprocessor controller, temperature calibration is inaccurate.

11.Failed microprocessor temperature sensor, calibration is inaccurate.

12.Failed lint chamber hi-heat switch (thermostat), opens at incorrect temperature.

13.Microprocessor temperature sensor is covered with lint.

NOTE: Lint accumulation on the sensor bracket can act as an insulator which will affect the accuracy of the automatic drying cycle.

Q.At completion of “AUTO” drying and cooling cycle, load is coming out over dried.

1.Percent of dryness (dryness level) of cycle selected is too high.

2.A and B factors not set correctly or “B” factor has to be adjusted for adverse location conditions.

R.At completion of “AUTO” drying and cooling cycle, load is coming out still damp.

1.Percent of dryness (dryness level) of cycle selected is too low.

2.A and B factors not set correctly or “B” factor has to be adjusted for adverse location conditions.

S.Main burners are burning with a yellow flame for gas models only.

1.Poor air and gas mixture (too much gas or not enough air) at burner.

a.Not enough make up air.

b.Restriction in exhaust.

c.Gas pressure too high.

d.Blower and fan (3 phase models only) rotating in the wrong direction.

e.Burner orifice size (D.M.S.) too large for application (i.e. high elevation).

T.Condensation on main door glass.

1.Too long, undersized or improperly installed duct work.

2.Back draft damper is sticking in partially closed position.

U.Scraping noise at basket (tumbler) area.

1.Check for obstruction caught in basket (tumbler) or wrapper area.

2.Basket (tumbler) is out of proper alignment.

a.Check both vertical alignment and lateral alignment.

b.Check gap between front panel and basket (tumbler), bearing set screws may have come loose, and basket (tumbler) walked forward or back.

V.Excessive noise or vibration.

1.Dryer is not level properly.
