1) Lint screen is dirty.
2) Restriction in exhaust ductwork.
2. Fault in burner hi-limit circuit or tripped manual reset hi-limit.
3. Fault in lint chamber sensor bracket or tripped manual reset hi-heat (limit) protector thermostat.
4. Failed DSI module.
5. Failed DSI ignitor/flame-probe assembly.
6. Failed microprocessor controller (computer).
ELECTRIC MODELS ONLY
1. Fault in sail switch circuit...
a. Sail switch is out of adjustment and/or failed.
b. Sail switch is not closing or fluttering...
1) Check blower (squirrel cage fan) motor and rotation direction.
2) Restriction in location exhaust system.
2. Failed oven hi-limit circuit.
3. Tripped lint compartment manual reset (225° F [107° C]) safety thermostat circuit.
4. Failed oven contactor/relay.
5. Failed heat selector switch.
STEAM MODELS ONLY
1. Fault in lint chamber sensor bracket or tripped manual reset hi-heat (limit) protector thermostat.
2. Failed microprocessor controller (computer).

Q. Dryer operates but is taking too long to dry...
1. Exhaust ductwork run is too long or is undersized...back pressure must be no less than 0 and cannot exceed 0.3
in WC (0.74 mb).
2. Restriction in exhaust ductwork...
a. Exhaust back draft damper is sticking partially closed.
b. Restriction in ductwork...check ductwork from dryer ALL the way to the outdoors.
3. Low and/or inconsistent gas pressure (for GAS MODELS ONLY).
4. Insufficient make-up air.
5. Poor air/gas mixture at burner...yellow or poor flame pattern; adjust gas burner air adjustment shutters (for
GAS MODELS ONLY).
6. Lint 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 ductwork (for GAS MODELS ONLY).
9. Failed microprocessor controller (computer)...temperature calibration is inaccurate.
