Hi my invoice # is 301182. I and rebuilding an Ashley 5500 XL Stove for a friend and I replaced combustion blower, distribution blower, igniter, feed motor, vacuum switch, and front door gasket.
The stove seems to run fine but it doesn’t always ignite. Ignition is very random. Sometimes it does and sometimes it times out. I changed pellets to fresh pellets, but it still happens. I’m wondering if you can tell me why the startups are so random. Doesn’t seem to be any reason for this problem wondering if you can give me some ideas as to why this is happening. Thanks, Lloyd.
Thanks for contacting us Lloyd, happy to assist. ignition is created when the intake air becomes super-heated as it passes over the igniter element. Any air loss or air blockage can create issues with consistent and proper ignition. Let’s start with the basics.
Air Loss:
– Inspect the Firebox Door Gasket and Glass Gasket – Tight Seals (With the stove off, use a dollar bill and place half in/half out. Shut the door and pull on the bill. Should be heavy resistance. Check in multiple areas of the door.)
– Inspect the Ash Pan Door Gasket if applicable
– I’m sure you placed in a new combustion blower gasket when it was replaced, just make sure it looks correct – both motor to housing, and housing to stove gasket seal.
– Burnpot Placement – Ensure the burnpot is seated down properly
Air Blockage:
– Check Burnpot Holes to ensure they are all open
– Check the air intake to make sure it is free and clear from all obstructions
– Check the exhaust to make sure it is free and clear
– Check the exhaust housing/passageway to make sure we don’t have built up ash
Lastly we can check the ohms of the igniter and voltage of the combustion fan during start-up. Being brand-new it would be rare, but we can certainly check them to be sure. Combustion blower should be near line voltage during start-up (105-120V). For the igniter in the 5500XL, the ohms should be in range of approx. 54 to 63.
