SECTION VI BCD-1 TYPE MODULE A. INTRODUCTION The Direct Spark Ignition (DSI) system operates at 24 VAC and is a discrete component based gas ignition control (DSI module) system, which utilizes a line frequency spark as an ignition source. Safe proof of flame is accomplished through flame rectification. The DSI module has a diagnostic light emitting diode (L.E.D.) indicating light, which simplifies troubleshooting in the event of a fault. Other Features...
The module also provides for safe proof of ignition. If a flame is not sensed by the flame-probe electrode (of the ignitor/flame-probe assembly) within a specified time frame, the module will de-energize the gas valve and the ignitor/flame-probe assembly, and go into the LOCKOUT mode. If a flame is established (sensed) but then lost (flame out due to possible air turbulence), the Direct Spark Ignition (DSI) module will wait 30-seconds then restart the ignition sequence.
IMPORTANT: THE GAP SETTING ON THE IGNITOR/FLAME-PROBE ASSEMBLY IS CRITICAL. d. The Direct Spark Ignition (DSI) 24 VAC gas valve(s) used are of the redundant type, which means the gas valve is actually two (2) gas valves in one (1); one (1) in series with the other. This is a safety feature, which provides protection against gas flow in the event of a failure of one (1) of the valves to seat properly.

D. TROUBLESHOOTING The troubleshooting information provided in this manual is intended for use only by qualified service technician. Observe ALL safety precautions displayed on the equipment or specified in the installation/operator’s manual included with the dryer. IMPORTANT: UNDER NO CIRCUMSTANCES SHOULD ANY SAFETY OR HEAT CIRCUIT DEVICE EVER BE DISABLED.
DSI IGNITOR GAP FEELER GAUGE (1/8”) MULTIMETER/VOLTMETER For checking the gap between ignitor assembly ground rod and spark electrode. Available from ADC - Part No. 305410 For measuring voltage and/or amperage 1. Direct Spark Ignition (DSI) Troubleshooting Terms (Definitions) a. LOCKOUT Mode - DSI module “GREEN” light emitting diode (L.E.D.) indicator light blinks continuously. This indicates there is a system fault and most likely the fault is that the DSI module was not able to ignite the gas. b.
2) Direct Spark Ignition (DSI) module light emitting diode (L.E.D.) indicator lights “GREEN” for up to approximately 1.5-seconds (prepurge). This indicates that ALL the controls (including ALL the safety circuits) are functioning and power is being supplied to the DSI module. a) DSI module L.E.D. indicator lights “GREEN.” This indicates a normal heating cycle. This also indicates that the preliminary diagnostics of the module has confirmed that the DSI module is functional. b) DSI module L.E.D.
1) To effectively use this information or the flowcharts (on page 37, page 38, and page 39), each step must be completed in sequence, performing whatever tests are suggested. After the completion of each test, the guide will direct the service technician to the next logical step in the troubleshooting sequence based on the outcome of the previous check. 2) Components should be replaced only after each step has been completed and replacement is suggested in the flowchart.
d. Troubleshooting Flowchart - Quick Reference... First Visual Check NO SPARK AND SYSTEM DOES NOT WORK Is 24 VAC available at transformer? NO Is 24 VAC present from terminal THS2 to ground? YES NO YES Is power available at primary? NO YES Replace transformer. Are thermostats contacts and limit control contacts closed? Close contacts. Determine why voltage is not present. NO YES Check continuity of wiring to determine why voltage does not exist at THS2.
e. Troubleshooting Flowchart - Quick Reference... Second Visual Check SPARK PRESENT BUT MAIN BURNER DOES NOT COME ON Is main valve wiring securely attached to terminal M.V.3 and ground? NO Is 24 VAC present between terminals M.V.3 and ground? YES NO YES Correct Replace Johnson Control module G760/761 Check for continuity in wiring from M.V.3 to gas valve, and gas valve to GR. Determine why continuity does not exist.
f. Troubleshooting Flowchart - Quick Reference... Third Visual Check MAIN BURNER LIGHTS BUT DOES NOT STAY ON Is flame sensor cable securely attached to terminal 4? NO Does continuity exist from control to flame sensor? YES NO Correct Replace sensor cable. YES Is flame sensor corroded or is ceramic cracked? Correct or replace sensor.
3. Troubleshooting/System Detailed Diagnosis When the dryer calls for heat, 24 VAC from the step down transformer is applied to the “THS” and “GND” (ground) terminals of the Direct Spark Ignition (DSI) module. The DSI module light emitting diode (L.E.D.) indicator will light “GREEN.” The gas valve will be energized, and the spark burst will be evident (on) for approximately 8-seconds at the tip of the electrode/flame-probe assembly. Flame should now be established/ confirmed.
a) Connect water column (W.C.) test gauge (manometer) to the gas valve pressure tap (1/8” N.P.T.). b) Start the dryer...with the burner on, the correct water column reading in inches should be: Natural Gas .................................. 3.5 inches (8.7 mb) water column. Liquid Propane (L.P.) Gas ............ 10.5 inches (27.4 mb) water column. When a gas dryer is first started (during initial time of installation or start-up), it has a tendency not to ignite on the first ignition attempt.
NOTE: To reset the Direct Spark Ignition (DSI) module if it is in the LOCKOUT mode, open and close the main door, then restart the dryer. (a) To check and/or set the 1/8” gap, use a DSI Ignitor gap feeler gauge (refer to the illustration on page 41) or similar type device to determine the gap size. DO NOT USE FEELER GAUGE TO SET GAP, use it only to determine the size of the gap. If an adjustment is necessary, bend the ground rod to achieve the correct gap, then recheck the 1/8” GAP with a feeler gauge.
NOTE: To reset the Direct Spark Ignition (DSI) module if it is in the LOCKOUT mode, open and close the main door, then restart the dryer. 4) DSI Module If there is some sort of operational interference in the DSI system, the DSI module (acting as the “controller” for the system) will go into a LOCKOUT mode (where the light emitting diode [L.E.D.] will BLINK “GREEN” CONTINUOUSLY). a) Operational interference is any adverse condition (whether internal or external) to the system.
a) Primary Side This is the incoming voltage side -120 VAC, 208 VAC, 230/240 VAC - of the transformer. b) Secondary Side This is the step down side - 24 VAC - of the transformer. WARNING: 208 VAC and 230/240 VAC ARE NOT THE SAME. ALL voltage connections should be checked and confirmed according to the wiring diagram provided with the individual dryer. Any damage done to dryer components due to improper voltage connections will automatically VOID THE WARRANTY.
(e) One (1) YELLOW or ORANGE wire supplies the 24 VAC signal for the control and/ or DSI circuit. (Refer to specific wiring diagram with the dryer for connection point.) 7) Direct Spark Ignition (DSI) 24 VAC Redundant Gas Valve There are three (3) DSI 24 VAC Redundant Gas Valves in use (refer to the illustration below and on the next page. The particular redundant gas valve that is used is dependent solely on the size (model) of the dryer.

SECTION VII TROUBLESHOOTING The information provided will help isolate the most probable components associated with the difficulty described. The experienced technician realizes that a loose connection or broken or shorted wire may be at fault where electrical components are concerned, however, not necessarily the suspected component itself. Electrical parts should always be checked for failure before returned to the factory.
IMPORTANT: The Phase 5 coin microprocessor controller (computer) has its own internal heat sensing circuit fuse protection, located on the back side of the controller. If a “dSFL” condition occurs, check to see if this fuse has blown. If it has, DO NOT replace the entire microprocessor controller (computer); replace the fuse and do so with a 1/8-amp (Slo-Blo) fuse only. NOTE: Once the microprocessor controller (computer) detects a problem in the heat circuit, it updates every 30-seconds.
NOTE: If the dryer is started (the light emitting diode [L.E.D.] display indicator dots are on) and there are no outputs (heat and/or motor output L.E.D.s are off) and the “dOOr” input L.E.D. is on, the fault is in the Phase 5 microprocessor controller (computer) itself. If the L.E.D. display indicators are on and the door L.E.D. input and motor/heat output L.E.D.
B. NO HEAT CONDITION (BLOWER IS ON) The following procedure must be performed with the microprocessor controller (computer) display in the normal operating mode, the heat indicator dot on, and the light emitting diode (L.E.D.) output light is on. Voltage is 24 VAC unless otherwise specified.
1. With the heat indicator on check for voltage at J1 connector 9-pin connector pin #8 (orange wire to ground) if 24 volt is present. 2. If no voltage (24 VAC) check for loose connection at 9-pin connector or problem may be faulty microprocessor. 3. Check for voltage (24 VAC) at J11 connector pin #3 orange wire. If no voltage, check for loose connection or bad basket (tumbler) hi-limit. If voltage is present, proceed to next step. 4.
C. NO START CONDITION Follow this test procedure, providing that the microprocessor controller (computer) is functioning where the display is in the normal operating mode and the motor indicator dot is on, and the light emitting diode (L.E.D.) motor output light is on. The voltage you should be reading is 24 VAC unless otherwise specified. 1. Check to see if “dOOr” L.E.D. input light is on. (Located on component side of the computer board.) If it’s off, refer to “dOOr” in the Troubleshooting Section. 2.
D. NO DISPLAY CONDITION NOTE: Regardless of the voltage (120-240 VAC) make sure the voltage selector switch is set to 115 VAC. 1. Check power supply. (Dryer voltage 110v, 208v, 220v) (Circuit breaker box or fuse panel) 2. Check fuse 2 (3/4-amp Slo-Blo) if blown, replace it. 3. Check for voltage at the (J5) 6-pin connector (120 VAC) pin #1 black wire and pin #2 white wire. If no voltage, check for a loose connection. 4. Check for voltage at the microprocessor pin #6 black wire and pin #3 white wire.
E. “dSFL” DISPLAY CONDITION When the display reads “dSFL” this condition indicates a fault in the microprocessor controller (computer) heat circuit. This circuit includes the microprocessor controller (computer), microprocessor temperature sensor (located in lint compartment) and wires to and from these two (2) points. 1. Check the 1/8-amp fuse on the computer board. If no continuity, replace with ADC PN: 136048. If fuse repeatedly burns out go to Step #3. 2.
F. “dOOr” DISPLAY CONDITION When the display reads “dOOr,” this indicates that there is a fault (open circuit) somewhere in the microprocessor controller’s (computer’s) door switch circuit. Include the door switch, microprocessor controller (computer) and the wires to end from these two (2) points. Before following this test procedure, check the component side of the computer to see if light emitting diode (L.E.D.) input light is on. If on and still reads door, replace computer.
