We moved into a house 4 months ago. It has a pellet stove that is 6 years old. We are troubleshooting some minor issues, but one in particular we cannot figure out and I cannot reach tech support. It's an Englander stove that is hooked up to a thermostat. Per the manual, the stove should not shut off when the set temperature is reached, it should maintain a low burn until it goes up again. Ours turns completely off every time then starts back up again when the temperature goes down. Any ideas as to what's going on? Any information would be appreciated.
