Fan relays

[jimmybob]

I have a bad fan relay. The number on it is BC-1526-AA. I have a new relay but the number on it is BC-7070-A/M. They look identical otherwise. Do you think it is possible to replace this new one with the old one? I have a Heil 80% furnace. The Model number is NUGK075DG07.

The important thing is that the coil voltage is the same on both of them and that the relay is able to handle the amperage of the motor.

This is a fan relay, they are all the same as far as residential goes.
