I have 2 Breckwell Big-E stoves, one of them is shutting down with a blinking #3 light, after ~15minutes. I have temporarily jumped the POF snap disk, and the over heat sensor, and the vac sensor, none of which made any difference. I also swapped control boards with my other known good stove, and got the same results. Both blowers are working, and the Auger is working right up til the shutdown sequence. I've done a full cleaning, but with all the sensors jumped, I wouldn't think that would matter. I have no idea what to try next, any suggestions?
