Have been a lurker here for some time and have received a great deal of good info over the years. I now have a problem that I have not seen listed here in the past, at least I can’t find anything in the forum that relates to this problem.
I have a Quadrafire Castile Insert, had it about 6 years and has been working flawlessly since new. It now will start normally via the thermostat and run normally for hours and then I find the call light on and no fire or unburned pellets in the firebox. If I hit the reset button, it will light and run normally and the same thing will happen, which may take an hour or more. Initially I thought it was not restarting during the day or night until yesterday when I was in the room while it was running. It seemed to be doing fine and then just stopped feeding pellets, and eventually the fire would go out. The auger made no noise oike it was jammed or anything. While this happened everything else seemed to work fine, both fans were running and flame was dancing correctly which told me I didn’t have a flue blockage like I have had in the past.
I tried to use the reset button when I realized what was happening, but apparently it won’t work until the fire pot temp reduced and the red light went out, then the reset button worked fine and it relit without a problem. During this time the call light was always on as the thermostat was calling for heat. Snap discs seem to check OK and vacuum hose is clear, in the beginning of the season I did a major cleaning , removed auger, both fans etc and everything seemed fine and it has worked flawlessly until about a week or so when this started. I didn’t check the snap disc when this happened, which I will do next time but the way it starts and runs so good at first leads me to believe they are OK. Plus I will have to be present in order to check it, because once it cools for 10 minutes or so it will relight with the reset switch.
I read a lot about the control box’s going bad but I don’t want to start throwing parts at it, especially expensive ones. I still have the original grey colored box, I understand the new ones are clear. It seems to me that something is getting hot and / or shorting out for a period of time. Any suggestions would be greatly appreciated, we are starting to get into single digits and I need it now.
Sorry to ramble on just wanted to offer as much information as possible.
Thanks in advance,
