I think my control box is not working to run the auger. Does anyone know how to troubleshoot the control box? The stove dumped a very large amount of pellets completely over flowing the burn box. Now the auger will not run. The ignitor is working fine. Thermostat is working fine. But the auger will not feed pellets. Checked the vacuum switch and that is working. I noticed a flashing blue light that flashes 4 times when it is turned on. Is this an error code? The box is a little pricey so I was looking for troubleshooting advice. Thank you
