4b) To check “Interlock 2” (Heater Doors), verify that there is a 110 VAC signal on TB-41, on the Main Electrical Panel, when PLC (Programmable Logic Controller) output #4 is on.

NOTE: The heater door interlock switches are double-pole double-throw (DPDT). These switches affect different circuits.

If there is 110 VAC at the panel go to paragraph #5b below.

If there is not a signal, check circuit back to the burner door switches. Refer to the AD-464 Solenoid Junction Box Wiring Diagram for connection information.

5b) A quick way to check the load and unload door switches is to close the unload door (2-Door models) and toggle the load door’s “wobble arm,” and monitor INPUT #6 of the PLC (Programmable Logic Controller). Likewise, for 2-door models, close the load door and toggle the Unload door’s “wobble arm,” also monitor INPUT #7 of the PLC.

NOTE: The rotary arm switches mentioned are double-pole double-throw (DPDT), where the PLC (Programmable Logic Controller) signal and “door” switch effect different circuits.

If input #6 L.E.D. (light emitting diode) of the (Programmable Logic Controller) goes on and off, the signal is “good.” Go to Section #5 on page 69 and page 70.

If input #6 L.E.D. of the PLC doesn’t react, then perform the following

Power down the dryer.

Close the Load and Unload doors.

Check for continuity between TB1-70 and TB1-7 on the Main Electrical Panel Refer to the AD-464 Main Panel Wiring Diagram.

If no continuity, refer to the AD-464 Tumbler Junction Box Wiring diagram for detail information for door switch wiring.

6b) To check interlock 3 (PRS1 and PRS2), Gas pressure Hi/Lo switch:

Power down the dryer.

Check for continuity between TB1-18 and TB1-19.

If no continuity, refer to the AD-464 Solenoid Junction Box wiring diagram for detail information for PRS1 and PRS2 wiring.
