ST Croix Pellet Stove Troubleshooting [7 Easy Solutions]

This troubleshooting guide contains the ST Croix pellet stove’s seven significant problems and solutions. Let’s start: 

1. Keeps Shutting Off

ST Croix pellet stove is an excellent heat source in your home, but it creates irritation when it frequently keeps shutting off. Your pellet stove keeps shutting off for the following reasons:

  • Stove’s faulty wiring
  • Dirty or defective combustion blower
  • Insufficient fuel in the hopper
  • Poor air adjustment
  • Infrequent pellet feeding
  • Stove draft fan’s low position

Solution:

When the pellet stove can’t function well, it shuts off abruptly. Fix the issue by following the ways below:

  • Inspect the home’s circuit breakers and voltage reading and replace the faulty wiring
  • Properly clean the pellet stove unit, including the combustion blower
  • Ensure the hopper has sufficient fuel
  • Ensure high air adjustment and adequate pellet feeding
  • Misaligned fan position causes weak flame. Thus inspect it and reposition it in the exact location.

2. Auger Not Working

ST Croix pellet stove auger not working problem indicates that it fails to turn on and stop feeding pellets. The following factors are responsible for this problem.

  • Pressure switch failure
  • Motor failure
  • Jammed auger due to improper pellet size

Solution:

Whatever your auger problem is, the best thing you can do is unplug your stove and test its auger motor by opening its compartment. You could also prevent the motor’s future lock-up by lubricating the components and adequately cleaning them. The other solutions are:

3. Won’t Turn On

Another major pellet stove problem that users frequently encounter is it won’t turn on. The factors that lead to this issue are the following:

  • Lack of power supply to the stove
  • Power surge
  • Tipped manual reset high limit switch
  • Controller board’s main fuse malfunction
  • Combustion blower issue
  • Ash builds up in the vent pipe

Solution:

Avoid leaving your pellet stove in the plugged situation for a long time, such as all winter or summer. Hitting the pellet stove for a long time causes a power surge in it, and you may even not be aware of it, thus avoiding it. The other solutions are the following:

  • Ensure adequate power supply
  • Replace the defective limit switch and main fuse
  • Contact a technician to inspect the combustion blower issues and fix it
  • Properly clean the vent pipe and vacuum tubing’s ash build-up

4. Won’t Light 

Another major problem with the ST Croix pellet stove is stopping lighting. The reasons behind this issue are:

  • Bad igniter
  • Moist pellet
  • Poor airflow

Solution:

You can prevent your stoves won’t light issues by following the solutions below: 

  • Use dry pellets
  • Replace the faulty igniter
  • Ensure proper airflow by checking the combustion blower and control board

5. Error Codes

Appearing error codes on the ST Croix pellet stove’s control board indicates something wrong with the stove. Pellet stove’s most common error codes are the following:

  • “E-1” – Vacuum loss
  • “E-2” – Light failure
  • “E-3″ – Over firing or stove is shutting down/”E-3”  means stove shutting down or over firing
  • “E-4” – Exhaust temperature dropping

However, your pellet stove could display the above error codes for the following reasons. The causes are:

  • Resisted combustion airflow causes vacuum loss. It also happens when the insufficient exhaust flow can’t hold the flue blockage.
  • If the stove fails to reach the minimum temperature within half an hour from the starting time, the furnace automatically turns off. And it displays the error code E-2
  • When the pellet stove reaches the temperature’s high limit, the furnace shuts down. This happens because the stove’s feed rate is higher than the convection blower.
  • Empty hopper feed causes dropping in exhaust temperature.

Solution:

If your pellet stove display shows “E 0,” it means it operates smoothly. Any other code on display implies an error in your stove, and you need the solutions for it. The general solutions to fix all these error codes are the following:

  • Ensure non-resisted combustion airflow and sufficient exhaust flow
  • Contact a technician to solve the temperature issue and ensure that your stove reaches the exact operating temperature properly.
  • Ensure that the stove’s convection blower rate is greater than the feed rate
  • Inspect the hopper feed and fill it if it’s empty

6. Keep Backing Up

If your ST Croix pellet stove improperly combusts pellets, your stove’s pellets will keep backing up. This issue can take place to the following factors:

  • Inadequate airflow or lack of oxygen
  • Low-quality pellets
  • Too quick pellet feeding rate
  • Shells stuck in the middle of the hopper and combustion chamber
  • Shots leaving massive ashes on the stove

Solution:

If your pellet stove keeps backing up, you could follow the ways below to prevent this issue. The solutions are the following:

  • Ensure sufficient airflow or oxygen to the furnace for burning pellets
  • Use high-quality pellets
  • Before starting each fire, properly clean the stove’s burn pot and ashtray 
  • Use exact size pellets to prevent its stuck in the chute
  • Properly clean the hopper or auger dirt, and ash builds up.

7. Not Feeding at Startup

Your stove may stop feeding at startup for the following reasons, even if its power is on. The reasons are: 

  • Faulty high-limit sensors
  • The pressure switch fails to close the circuit
  • Auger jam

Solution:

The fixing ways of the above problems are the following: 

  • Replace the defective high-limit sensor
  • Ensure the pressure switch is appropriately closing the circuit
  • Use the right size pellet

  1. 20 year old St.Croix Afton will feed manually but not automatically. Feed light comes on but auger doesn’t turn on auto. Select feed of 1, 2, 3, ect. means the feed light stays on longer for each as expected. Is a replacement control board available for this older stove? Am I SOL?

    • Hi Bill

      Check the hopper whether it is empty or not. If empty, fill it and wait for a few minutes so that the unit augers the pellets onto the burn pot. Also, check the venting that may be blocked. As a result, the power switch senses airflow lacking and shuts off the motors. So, try cleaning the venting.
      If it doesn’t work, take help from a technician.
      Well, you can try online for your control board or contact St.Croix support center.

      Thanks
