check your themostat fan mode switch to see if it in on or auto. It should be in auto. If this does not stop indoor fan motor, (it may take up to 2 minutes for the fan to stop, preprogrammed shutoff in the thermostat and fan control cards may make you think the fan has not stopped ) If this does not stop the fan the fan control board in your air handler has a green wire shorting to 24 volt signal in the theromostat wire or the contact on the blower control card is stuck and will need replaced.
Hello, if the outside unit is not running check tje power supply to make sure you are getting 240 volts, also make sure the contactor coil is receiving 24 volts, if you are not getting 24 volts at the contactor then it may be a bad thermostat, control board or the thermostat wiring is loose or perhaps cut somwhere. If you have 24 volts at the contactor and does not energize than replace the contactor coil.
If you changed the unit but didn't change the thermostat it is possible that the thermostat that you have will not work with that unit. I see that the unit you installed is a heat pump, you may have a straight cool T-Stat. If you put the T-Stat in the "Auto" "Heat" mode the outdoor fan and the compressor should be workng as well as the blower fan. If it turns out that the outdoor fan and compressor are not running you will want to buy a Thernostat that is compatable with heatpumps should be 2 heat/ 1 cool
That does not sound normal at all, I have a Goodman Heatpump and the Fan on the Evaporator (outside unit) should run as soon as it starts up! The only delay you should be seeing is when the unit starts, the fan in the AHU starts 5 seconds after and runs for about 1.5 minutes after shutdown.
the motor could just be locked in place from sitting...take a stick or something and try to see if it spins be sure of rotation! you can also give it a little nudge while it is on and it will take off! if this happens then you have a bad start compacitor but no there are no fuses that only protect the motor!
First,Turn on the heat cycle (Not Emergency)and see if the outside unit come on,If not,and you don't have low voltage outside,Go to the inside unit and test the transformer,If you have low voltage from the transformer but not outside,It is the low voltage wires,If you don't have low voltage from the transformer,It's the transformer.If you have low voltage outside when in heat mode,but the unit won't come on,It's the contactor.Let me know if you need more help.
