I have a Hearthstone LP gas-fired direct vent heater (Sterling-Ht 8532 - with the remote) and blower (95-57320). The heater works fine however the blower never turns on. The blower has a variable speed switch on the left and an on-off-t'stat switch on the right of the heater. No combination of things I have tried (with the heater on or off) has worked. I am the second owner of the heater (was installed in the house when we bought it) and I have never seen the blower work. I removed the blower from the unit but I'm not sure what to troubleshoot. It looks like from the power line there is a connection from the variable speed switch and another connection to a place on the heater. Is anyone familiar with how the blowers function and what could be wrong (haven't seen any fuses anywhere...). I'm very new to this so any advice would be helpful. Thanks!
