J.No display condition or display reads “Low Voltage Fault”.* (Refer to page 54)

1.Check for line voltage (120, 208, 240, etc.) in the rear of the dryer at the distribution block. If no voltage is present, the problem may be a faulty or tripped breaker. If voltage is present, check for line voltage (120, 208, 240, etc.) at FIA (refer to illustration on page 54) to neutral. If no voltage is present, check for blown fuse or loose connection.

2.If voltage is present, check for voltage (24 VAC) on the motor contactor T3. If no voltage is present, check for a loose connection. If connection is fine, replace the transformer. If voltage is present, check for 24 VAC at the J17 connector on the pink wire pin 3 to ground. If no voltage is present, check for a loose connection.

3.If voltage is present, check for 24 VAC on the microprocessor J8 connector pin 1 pink wire to ground. If no voltage is present, check for a loose connection. If voltage is present, check the 1/2-Amp fuse on the computer board marked “F1.” If fuse is not blown, then the problem is a faulty microprocessor.

K.The display reads “Open Sensor Activated Fire Extinguishing (S.A.F.E.) System Probe Fault”. (Refer to page 55)

1.Check for a loose connection or shorted wire at the microprocessor at the J3 connector pin 7 red wire to the J10 connector pin 1.

2.Check for a loose connection or short in the wire at the microprocessor J3 connector pin 8 black wire.

3.Check for a loose connection at the 2-pin connector P10.

4.S.A.F.E. system probe may be shorted and needs to be replaced.

L.The display reads “Cycle Paused, Main Door Open”. (Refer to page 56)

1.Make sure main door is closed.

2.Make sure main door has good contact with the main door switch.

3.Check for a loose connection at the microprocessor J8 connector pins 5 and 6 orange/silver wires.

4.Check for a loose connection at the connector pins 1 and 3.

5.Check for a loose connection at the main door switch.

6.When the door switch button is in the closed position, check for continuity. If no continuity, replace the door switch.

M.The display reads “Cycle Paused, Lint Access Open”. (Refer to page 56)

1.Make sure lint drawer is closed.

2.Check for a loose connection at the microprocessor J8 connector pins 3 and 4 orange/silver wires.

3.Check for a loose connection at the J18 connector pins 1 and 4 orange/silver wires.

4.When the lint drawer switch is pressed in, check for continuity. If no continuity, replace the lint drawer switch.
