1.Failed microprocessor controller (computer).

G.Microprocessor controller (computer) will not accept any keyboard entries, i.e., display reads “FILL” and when keyboard entries are selected, the display continues to read “FILL.”

1.Failed keyboard label (touchpad) assembly.

2.Failed microprocessor controller (computer).

H.Microprocessor controller (computer) will only accept certain keyboard entries.

1.Failed keyboard (touchpad) assembly.

I.Microprocessor controller (computer) locks up and display reads erroneous messages or only partial seg- ments.

1.Transient power voltage (spikes) disconnect power to dryer, wait one (1) minute and reestablish power to dryer, if problem is still evident.

a.Failed microprocessor controller (computer).

b.Failed keyboard label (touchpad) assembly.

J.Dryer stops during a cycle, microprocessor controller (computer) buzzer (tone) sounds for 5 seconds, and then the L.E.D. display reads “dSFL,” for approximately 30 seconds, and then returns to “FILL.”

1.Loose connection somewhere between the microprocessor controller (computer) and the microproces- sor temperature sensor.

2.Loose “dSFL” 1/8 amp fuse on the microprocessor controller (computer).

K.Dryer stops during a cycle, microprocessor controller (computer) buzzer (tone) sounds for 5-seconds, and then the L.E.D. display returns to “FILL.”

1.Loose connection somewhere in the main power circuit to the microprocessor controller (computer).

2.Failed arc suppressor (A.S.) board (reversing models only).

L.Microprocessor controller (computer) L.E.D. display reads “Hot.”

1.Possible overheating condition, microprocessor controller (computer) has sensed a temperature which has exceeded 220º F.

“Hot” display will not clear until temperature sensed has dropped to 220º F or lower and the microprocessor controller is manually reset by pressing the “CLEAR/STOP” key.

M. Heating unit is not operating (no heat), no voltage at heating unit (i.e. gas model DSI module, electric oven contactor) when dryer is first started and both the heat indicator dot and the “HEAT” output are on.

a.Sail switch is out of adjustment or has failed.

b.Sail switch damper is not closing or is fluttering. 1.) Lint screen is dirty.

2.) Restriction in exhaust.

3.) No exhaust air flow. a.)) Failed fan
