Fan does not come on when heat starts. Most of the time, now, the heater comes on (at thermostat - heat -), coils get hot, no fan. to the point I am selecting fan on thermostat to disperse heat from coils. From what I've learned.
1. Thermostat starts heater and low fan - (Mine: coils heat - NO fan)
Am I right to suspect the Sequencer or what would be 1st step?
