Anyone with an ICM controler on there sleeve bearing furnace... Looking for some input. How slow does your fan go when it's about to kick off? I tried my ICM hooked upto blower speed 1 and also tried blower speed 2. Got similar results works great!! Just don't want to cook the motor. I like it hooked to blower 2 better for the simple fact its quieter at crusing temp with the odd surge to bring the plenum to the set temp. (Has little wider band for cfm output) I have the ICM currently on max cutoff for sleeve and max hard start to ensure adequate lubrication. The system seems to be working as expected. I'm not to consurned with the voltage... more so with the speed of the shaft to get proper oil. When the plenum temps drop to around 100f it is SLOW! But I'm not used the it.
