Why is there spark but no flame in my Alliance Laundry Systems Dryer?
If your Alliance Laundry Systems Dryer shows a spark but no flame, verify that the gas is on and that there is 24 VAC at the gas valve. If 24 VAC is present at the gas valve, the control might be faulty. Check the voltage between the gas valve terminal MV and GND on the control.
What to do if the Alliance Laundry Systems Dryer valve is on but there is no spark during TFI?
If the valve is on but there is no spark during TFI (Trial for Ignition) in your Alliance Laundry Systems Dryer, consider these potential causes and solutions: * A shorted electrode may be the problem. Ensure the spark gap is correctly set between 0.094 and 0.156 inches. * A faulty high voltage cable or a poor connection can prevent spark. Check the high voltage cable. * A control failure can also cause this issue.
How to fix Alliance Laundry Systems Dryer when flame is okay during TFI, but there is no flame sense after TFI?
If your Alliance Laundry Systems Dryer has a flame during the TFI (Trial for Ignition) but loses flame sense afterward, check the electrode position and cleanliness, inspect the high voltage wire, and ensure there's a good ground at the burner. Also, check the flame current.
What to do if my Alliance Laundry Systems Dryer control is in lockout mode?
If the control in your Alliance Laundry Systems Dryer is in lockout mode (70458701 Control Only), a manual reset is needed. Reset it by pushing the red lockout button or using the front end control.
Why does my Alliance Laundry Systems Dryer thermostat turn on, but there is no spark or valve activation?
If the thermostat in your Alliance Laundry Systems Dryer is on, but there is no spark or valve activation, it might be a bad control. Check the red LED for steady on or flashing codes. Also, check if the cable connects to the control and electrode, and if there is voltage present at the gas valve.
How to fix reset failure on Alliance Laundry Systems Dryer?
If you are experiencing a reset failure on your Alliance Laundry Systems Dryer, it could be due to: * The reset switch being pressed for too long: Try resetting again. * A shorted reset switch: Replace the switch.
