My 2000 Quadra Fire Castile, has developed a problem the convection (lower) blower. The stove starts and runs fine. The fan comes on after a few minutes like it's supposed too. If I select high fan speed, the fan will start to increase and then the unit goes into a resetting loop. It sounds as if the fan stops for a split second and then restarts only to quickly repeat. There is a relay on the board that is clicking at each reset. If I switch back to low I have to lower the thermostat for a second, stopping the call for heat and then turn it up and the stove will work fine again.
