1999 alfa ideal heat pump heats to temp but fan doesn't shut off is there a relay issue

SOURCE: heat pump is not kicking in no heat at 42 degree outdoor temp

check the wirings.the coils and also the heating element.also check the heating temprature.
also check the power outlet.
connect some where else.
and try to restart it again after five minites.after you unplug the device from the electric outlet.

the thermostat sub base has a place to connect a wire usually white to energize the heat strips when you push the stat way hotter than the house temp. that is why the strips come on in normal heat. it also has a terminal that is only energized in emergency heat and it also should have a wire connected to it so that terminal can supply power to the strips when the stat is switched into emerg heat . you can identify the terminal from the wiring diagram and if need be jumper w2 wire over to the aux terminal and it will work. they both go back into the airhandler and power the same strips. w2..................................................................................................w2 in airhandler to strips or w2...jumper to aux......................................................................................................................w2 in airhandler to strips.

First, with the unit not running, check to make sure the fan spins freely. Next check the capacitor. You can do that with a multimeter or look at it and if it looks swollen then it is most likely bad. Replace it with one of the same rating. If the capacitor is good then use an ohmmeter to check the fan motor windings. Also check the condition of your contactor and make sure the ciruit breakers are closed and the fuses are good. The breakers should be off before you check the capacitor, fan motor, and contactor.

The fan needs to be cleaned and lubbed. If this cannot be done then replace the fan.
