American Dryer Corp ADG-464 manual

•If no voltage is measured;

•Start a drying cycle, and monitor the voltages on TB1-23 and 9.

•If a voltage is present during drying start-up, the switch is functioning.

•If a voltage is not present while the dryer is started, check:

•Air Switch Adjustment.

•Switch.

•Circuitry (AD-464 Main Wiring Diagram and AD-464 Solenoid Junction Box Wiring Diagram). 3b) To check the electrical actuating of the pilot gas valve.

•Shut the main gas valve to the dryer.

•Open the disconnect block on TB1-63, for circuit testing. With control voltage “ON”, apply a 100 VAC line to TB1-63. THE PILOT GAS VALVE SOLENOID SHOULD ACTIVATE.

•If the solenoid does not cycle check circuitry; ADG-464 Main Wiring Diagram, and ADG-464 Solenoid Junction Box Wiring Diagram.

•Check gas valve solenoid.

•Retest.

•With the main gas valve OPEN, close disconnect block on TB1-63 and Measure for 110 VAC on TB1-63 and TB1-9 on the Main Electrical Panel during a drying cycle start-up.

•If a 110 VAC is present during start-up, burner pilot output circuit is OK.

•If a 110 VAC is not present;

•Check circuitry; refer to ADG-464 Main Panel Wiring Diagram and ADG-464 Solenoid Junction Box Wiring Diagram).

•Refer to Section VI, Part D, Gas Burner and Ignition System on page 37 thru page 45. 4b) To check the electrical actuation of the Ignition Transformer;

•Shut the main gas valve to the dryer.

•Open the disconnect block on TB1-65, for circuit testing with control voltage “ON”, apply a 110 VAC line to TB1-65 “output” ARCHING SHOULD OCCUR AT THE SPARK IGNITER IN THE BURNER ASSEMBLY.

•If there is arcing, close disconnect on TB1-65.
