Goodman electric heater is blowing cool air, it was blowing hot air the model number is A2408 thanks

UTL model number posted. Need exact model number for an exact answer.

Goodman units have relays in some and heat sequencers in others. Take an electric meter and sound out the circuits to see what the failed part is. Also make sure all circuit breakers are turned on to make sure the unit is getting full power. Careful during testing electric can be dangerous.

Depending on how many heat strips you have there are that many fuses that can go bad inside the heating area, also the same amount strips can purn out. So my first thing to do would be to check the continuity of the heat strips If you don't get any resistance with an ohm meter is is either fuses of coils.

Also you have 240 volt breakers for your heating and it will be different that what might be in you regualr breaker box, check them.
