I have a quadrafire mt vernon stove. It sat for a few years not being used cause it wasn't working. After doing some work on it including, changing the thermal couple, replacing snapdisk #1 and 2 and cleaning the system everything is working. However the convection blower is only staying on for 10 seconds and then shutting off. It won't stay off for long, only 10 seconds, then start again. But it's doing this on any setting I put it on. If it's on setting 4 it'll stay on for 15 seconds. But still on and off. Anyone got any idea's?? Thanks
