American Dryer Corp ADS-464 II manual If NO, refer to paragraph #1 above

Page 49

If RTD (Resistive Temperature Device) probe is defective, replace the probe.

NOTE: If ALL systems check out fine, call the ADC Service Department at (508) 678-9000.

2.No Control Power (“Blue” Light Off)

a.PROBABLE CAUSES;

1)Line voltage from main fuse disconnected.

2)Main disconnect on the dryer is turned off.

3)OL11 (overload #11) tripped.

4)Fuse #1 is blown.

b.POSSIBLE SOLUTIONS;

1)Verify main line voltage to dryer

If line voltage is present go to paragraph #2 below.

If line voltage is not present check fuse disconnected and retest.

2)Attempt to turn the dryer main power handle to the “ON” position

If the switch does not engage, verify that sprinkler power is “ON” (“red” light on main door).

If “NO,” refer to paragraph #1 above.

3)Open main enclosure and verify that OL11 has not tripped

If “YES,” check circuit, restart and test.

If “NO,” go to section #3 on page 46.

Verify that fuse #1 has not blown, check that the “RED” L.E.D. (light emitting diode) indicator is off.

If “ON” (fuse block L.E.D. “ON”), check circuit, replace fuse and test.
