Temperature Activated Blowers

We have the factory blower kit on our Lopi Liberty. It doesn't come on until the stove has been at temperature in the normal operating range for a while. It seems to be a function of both temperature and time, not sure, and I really haven't taken any close observations. The thermostatic fan controller is integral with the fan assembly, so it's mounted to the bottom rear of the box. The fan continues to run after a fire has completed its burn cycle, presumably until the stove temperature comes down to some point where there's not a lot of heat left to move around. Makes sense to me. Actually, the fan on a gas-fired furnace does pretty much the same thing, it's just a somewhat quicker sequence in that case. Sounds to me like your fan is operating perfectly normally. Rick

That's pretty much how mine works.

I've noticed mine will kick on quicker with less ash in the stove. Presumably it acts as an insulator reducing heat transfer to the front bottom of the stove where the blower/temp sensor is mounted.

On my used Olympic insert, I replace the older fan with one with the temp control. I could not get the sensor to properly sit on the bottom of the stove due to the hole size. At first it work pretty good, around the temps you mentioned. But it started giving me problems, by not coming on until the stove was really hot (600+) and then would click off once the fan would come on, then back on etc.

So I by passed the sensor and removed it. Now I wait until the stove reaches a good temp (400 or so) and then turn it on. Sure it stays on after the stove has cooled overnight (buring crappy wood so no long burns this winter) but at least I do not have the on/off issues anymore.

Our Hampton blower turns on and off right around those temps also.
They use a "clicks-on" bi-metal disc in the Hampton as the thermostat. Very crude, but simple and effective.
Let's hope it's also...Long Lasting

On my old Russo, I mounted a computer muffin fan into an 8" elbow. Mounted that & ran the cord to a timer. Set the timer to shut off about 5 AM. Works great & can't be any cheaper.

I have the same stove as shop-dog, same experience.
