Yes, but the thermal switch should really be opening before the fuse blows. I also measure the resistance of the heating element thinking maybe it was too low, but it was spot on. I checked the fan on the motor thinking maybe it was just slipping on the shaft and not turning, but it’s solid. Everything is perfectly clean now and I put my hand by the exhaust and it is blowing nicely. The thermistor shouldn’t really matter to this, maybe it’s not working and it would mask the problem if it was working, but with no obstruction on the vent, proper heating element, and fan blowing air, the fuse shouldn’t be blowing. It’s quite frustrating as this is not that complicated.
