My brother has owned a Winslow PS40 for several years. The stove is kept very clean and in excellent working order, burning about 4 tons per year with little or no problems. Last week he had to replace the auger motor. The change went well, but it seems the stove is running way too hot. The side doors are too hot to touch. This doesn't seem right as one of the doors houses the control panel. The feed light turns on every 2 or 3 seconds. He typically runs the stove on number 4 during the coldest periods. Anyone have any thoughts?
