25 6. Heat Condition (n-ce and n-australian Models) WARNING Machine Troubleshooting To reduce the risk of electric shock, fire, explosion, serious injury or death: Disconnect electric power to the tumble dryer before servicing. Close gas shut-off valve to gas tumble dryer before servicing. Close steam valve to steam tumble dryer before servicing. Never start the tumble dryer with any guards/panels removed. Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the tumble dryer is properly grounded. W002R1 Ignition Control Module Function There are four components to the ignition system: the module, the spark igniter, the high voltage cable and ground wire. When 24 VAC is applied between the TH and GND terminals on the module, the module will send the high voltage signal to the igniter and 24 VAC to the gas valve coils. Gas will hit the sparking igniter and flame will be established. The igniter being engulfed in flame will create a millivolt electric signal that is sent back to the module by the high voltage cable; this is what them module sees as flame recognition. If the millivolt signal is not at the module in ten seconds, the module will go into safety lockout. The voltage will be cut from the igniter and gas valve coils and will not be restored until voltage is cycled at the module. Intermittent Heat Test Procedure On ignition control modules with date codes higher than 08t2, perform the following test. Start the tumble dryer and run for 10 minutes (verify that the tumble dryer is heating properly). After the 10 minute cycle, re-start the tumble dryer and once again verify the unit is heating. Repeat this procedure 3 times. If the tumble dryer passes this test, the ignition control module is operating properly and SHOULD T be changed. Refer to Troubleshooting Manual for additional service procedures Copyright, Alliance Laundry Systems LLC DO T COPY or TRANSMIT 23

26 Machine Troubleshooting 6. Heat Condition Is the Ignition Control Module s red light on? Refer to Paragraph 7. Does the igniter spark? Is there 24 volts AC between the TH and GND terminals on the module? Refer to Paragraph 7 for heat circuit troubleshooting. Replace igniter and high voltage lead. Retest unit. If unit still does not spark, replace module. Does the igniter spark but no flame is produced? Is there 24 volts AC at the gas valve coils when igniter is sparking? Check wiring between gas valve and module. If wiring is good, replace module. Verify that gas is supplied to the machine. If gas and voltage are present, replace gas valve or coils. Does the flame turn off after igniter stops sparking? Is the igniter positioned properly in the flame, and does the flame look good? Is there continuity between GND terminal on module and machine? Replace module. Adjust position of igniter and retest. Verify machine is properly grounded. Replace igniter and high voltage lead. Retest unit. If it still does not sense flame, replace module.
