My distribution blower rarely turns on anymore, if at all. And the stove never stop running. So its not like my room reaches temp and the dist. fan turns off and eventually the stove burns out......my stove continuously runs non-stop. I'm in room temp mode. Any ideas? Is this normal? From what I can remember of the last 2 seasons the stove will light....once it gets hot enough dist fan turns on.....warms room to desired temp....then dist fan turns off and stove slowly shuts down the fire until the nest time it needs to heat up. Thanks in advance for your help!
