Does anyone experience furnace does not start fire while its fan starts? When I set to 90F of the furnace of my 2006 Grandby, the fan turns on and then off after 30 sec. or so on 80% of times. The most probable cause is its micro switch does not blow away by the fan. Does anyone experience? If so, how do you fix? Replace the fan? Apply lubrication to the micro switch? How do you expose the micro switch?
