St Croix Blinking heat level 5 light

Hello
Anyone see this? What does it mean?

New control panel installed on 11-09-2015
Digital Control Panel for St. Croix York Insert- 80P30523B-R

New Auger turns with line cord but does not turn after stove is turned on.
When Stove turns on and both exhaust and convection blowers come on. Auger never turns before erroring out with # 5 light Blinking.

See Video - St Croix Heat Level 5 Blinking
St Croix York Insert Blinking Heat level 5 light

Tried jumping out high limit snap disc and vacuum switch and # 5 light still blinks
See wire diagram on stove in pic below.

 

I have no idea what the #5 light means, AFAIK, only #2,#3, will blink. On mine, the blowers turn off when the vacuum switch is satisfied, and the startup sequence begins. If the vacuum fails after a certain time, the #2 light blinks.

 

This guy has the same problem!
St Croix Auburn Blinking #5 and steady #3 - Tapatalk
I'm in need of some help. I bought a St. Croix Auburn about 2 weeks ago and it has been running great. I'm burning Oak pellets. Today I woke up and the stove had shut off and the #5 LED was blinking. I unplugged the stove and then plugged it back in and re-lit. The stove immediately turned off the blower and the #3 LED is constantly on and the #5 light is blinking. I can't find in the owner's manual what this combination of lights indicates. I did just clean the stove 2 days ago and it ran fine up until this morning.

I just tried letting the stove cool and re lighting it. Now the #1 LED is solid, and the #5 is blinking. The stove's blower kicked on after about 5 minutes but the #5 light still flashes, the power light is off, and it is not feeding pellets.

However no info in the owner's manual for 5 light blinking
From the manual -- http://www.ncsg.org/wcmedia/documen...Digital_Control_Board_Service_Manual-2009.pdf
LED light 2 flashing - The number 2 LED light on the Heat advance bar will flash if the control board senses a loss of vacuum. The stove shuts down and the Number 2 LED light starts flashing approximately 60 seconds after a loss of vacuum has been sensed. (Fig 11)

LED light 3 flashing - The number 3 LED light on the Heat advance bar will flash if the control board senses a loss of Proof of Fire. The stove shuts down and the Number 3 LED light starts flashing after the stove cools down and the fans shut off. Approximately 30 minutes. (Fig 12)

LED light 2 and 3 flashing at the same time – This will indicate that the High Limit Switch has tripped and shut the unit down. Reset the High Limit Switch before diagnosing the unit. (Fig 13)

The auger motor is not turning when stove is first turned on.
The manual does say this so could be a bad control board.
First turn the stove on and see if it feeds pellets during the start-up cycle.
ATTENTION: The auger will only run for 2 minutes after the control board is turned on and then shuts off to complete the ignition cycle. Be sure to check it during the initial 2 minutes.
If it doesn’t feed pellets, check the following:
Check to see if the Auger Motor is running but the auger is not turning. This may indicate either a loose setscrew on the auger shaft or a stripped out gearbox.
If the Auger Motor tries to start and immediately stops usually means a foreign object is stuck in the auger system or the Auger is jammed on pellets. First take a quick look up the drop chute area in the front of the stove to make sure it’s not jammed there. Dislodge the pellets if a jam is found. Page 33 If nothing is found in the drop chute area, empty the hopper and visually inspect the opening to the auger. If nothing is found, the auger will have to be pulled from the hopper to see if the obstruction is farther up in the tube.

If the Auger Motor does not appear to be running or trying to run, it may be a problem with the power to the motor. Check for intermittent Line voltage on the Yellow wire plugged into the auger Motor. Voltage should be cycling ON and OFF when the Auger light on the control board blinks. If there isn’t any voltage at the Auger, carefully check for voltage on the pin-out on the control board. If no Intermittent voltage is present on the control board, the control board is bad and needs to be replaced.
