  If the Alliance Laundry Systems Dryer shows a valve on but no spark during TFI (Trial For Ignition), several issues could be at play. First, examine the electrode for any shorts. Second, ensure the spark gap is correctly set between 0.094 and 0.156 inches. Next, inspect the high voltage cable for any faults or poor connections. Finally, check for a control failure.

  If your Alliance Laundry Systems Dryer exhibits a spark but no flame, start by verifying that the gas supply is turned on. Next, check for 24 VAC at the gas valve. If both are present, check the voltage between the gas valve terminal MV and GND on the control to rule out a bad control.

  If the Alliance Laundry Systems Dryer has flame okay during TFI, but no flame sense after TFI, you should check the electrode position and ensure it's clean. Also, inspect the high voltage wire. Another potential cause is a poor ground at the burner, or a poor flame, so check the flame current.
