Hello
This video shows the flashing lights on a 7 year old Travis Avalon Arbor Pellet Stove.
See video
If # 4 Heat output light is flashing:
Owners manual says!
Heater Ran Out of Pellets
• Heater Did Not Start-Up Correctly
• Power Outage
• Restrictor Not Set Properly
• Burnpot Clogged
• Air Leak
• Heavy Ash Build-Up
In this case none of the above is true
Service manual says!
Fault and # 4 (MED) Light Flash = System Snap Disk Fault (pellets run
out & stove goes cold)
Diagnostic Codes (Qualified Service Personnel Only) - Continued
System Snap Disk Fault
Page 4
Fault light and #4 heat indicator blinking.
This fault code is caused by a heat sensitive switch that tells the control
board if the appliance is hot or cold. During operation if the unit runs
out of pellets or looses its fire this switch will communicate to the control
board that the stove is getting cold. The control board will shut off the
auger functions and initiate a twenty minute combustion fan safety cool
down. Another condition that will trigger this fault code is a failed start.
When the appliance is started the control board initiates a 30 minute
timer, if the appliance is cold at the end of this 30 minute start up timer
the control board will indicate a #4 fault and initiate a 20 minute
combustion fan cool down.
Likely cause are:
Unit ran out of pellets.
• Fire went out during operation.
• Unit was cold at the end of a start cycle (fire did not light).
• Faulty snap disk. -- Bingo ! ! !
Therefore I replaced the system disc
Also put in 2 new Hi Limit switches
Has anyone seen this failure?
