I bought a used m55 knowing that I needed to replace blower for overheats. Installed stove planning on running on low until blower comes. Installed turned on stove. Set to manual. The temperature indicator has a red light at 5 and 1. The stove fans kick on etc...no pellets drop. After 5 minutes or so the 4 starts blinking. The heat sensor didn't seemed tripped nor has it been running. This is all from cold start. Any ideas?
