I have a Bryant Heat Pump, model# FC4CNF048. Earlier this year in the summer around August did replace the thermostat and contactor due to lightning strike to house. A/C worked fine during rest of summer, but recently switched to heat for the winter. Programmed thermostat recently for 4 diff temp setting throughout the day. This worked well for several days, then I noticed the fan continuously ran. Reduced temp on thermostat, shut system off at thermostat, disconnected green wire at thermostat, pulled thermostat off and fan contiued to run. Only way to stop fan was to flip the circuit breaker in the main house panel. Any suggestions.

Are you talking about the indoor fan or the outdoor fan?

The indoor fan. This is the blower that circulates the air throughout the house.
