American Dryer Corp ADG-464 manual HI-TEMP Fault Message

b)POSSIBLE SOLUTIONS

1b) Visually check that the fan (Blower) rotate in the direction of its arrow.

•If rotation is incorrect:

•Check rotation of the main fan blower ...

If the motor direction is wrong, swap phase 1 and phase 2 of the incoming power in the main electrical enclosure.

•Retest

2b) Check the lint chamber air pressure switch. Check the lint chamber pressure switch with control voltage “OFF”. Open disconnects on TB1-20 and TB1-21, and check resistance across the outputs of these two (2) connectors. (Refer to ADG-464 Main Panel Wiring Diagram). This will verify that the switch is open when the dryer is “OFF”. Check the lint chamber switch during a “DRYING CYCLE” close the disconnects on TB1-20 and TB1-21, and measure 110 VAC between TB1-9 and TB1-21 during a “DRYING CYCLE.”

•If 110 VAC is measured the switch is functioning OK.

•If 110 VAC “IS NOT” present;

•Check switch’s pressure adjustment (refer to AD-464 Ladder Diagram for reference)

•Check that switch cover is in place and screws are snug.

•Check that lint screen is clean.

•Check that wiring; refer to following wiring diagrams:

•AD-464 Base Junction Box Wiring Diagram

•AD-464 Main Panel Wiring Diagram
