You may have a problem with the board or the motor, as there is a separate speeds for heating and cooling. I would call a competent, NATE certified technician to daignose this properly.

To me it sounds like you need a fan limit switch to sense temperature increase and turn your fan on. At least you know that everything else is working. With out a schematic I can not tell you what type of limit this would be but I would look for a sensor either mounted right above the coils or beside them.
Have you looked on the inside of cover plate for heating and blower compartments.Often times they will put a wiring diagram there. Wished I could be of more help. Thank you

Energy Knight heat pump refuses to blow!


Does this problem happen when the temperature is below 30 degrees? When it gets about that cold outside, the air outside is too cold for the heat pump to "steal" heat from. On the thermostat you'll find a switch labeled aux or emergency heat. Turning this switch on will operate a traditional coil heater inside the system, providing you with heat. The only downfall to this is that it uses more energy to heat this way. Try turning the fan switch from "auto" to "on". If the fan comes on, then we can rule that out. If the aux heat switch is NOT on, set the thermostat such that the system will try to heat. If the outside unit is running, the problem is either it being too cold like I said earlier, or there's a problem with the heat pump's mechanical system that needs to be serviced by a professional. If the outside unit doesn't run but it should be, check it's breakers at the panel, the breaker inside the electrical box that feeds it, and look to see if there's a reset button on the unit itself. Finally, check the air handler (part of the system inside with the fan in it) to see if there's any circuit breakers or fuses on this unit. Make sure they're not tripped/blown. If none of this helps, you definitely want to get a pro to work on your system.

Goodman a/c works, heater will work fine then fan will stop


you have a circuit board acting up. Try keeping the fan in the "On" position. It will keep the blower on all the time but it may work. There is a built-in delay not allowing the unit to come on after you reset it with the thermostat, wait three minutes or so to see if it comes back on. I still suspect a bad circuit board.
