If you have three compressors you need 3 relays.

The fan function was not changed only the compressor function.

If either fan fails to activate, the compressor will eventually overheat tripping the circuit breaker. Adding the external relays will do nothing to address this issue.

Let’s determine why the fan is not turning.
It could be a faulty capacitor for the fan.
It could be a failed circuit or connector on the circuit board.
It could be a failed fan motor.
It could be a faulty thermostat.

Is it the indoor or outdoor fan that is not working?
Do you have the SCS manual, excellent trouble shooting steps in the manual.
Are you comfortable working with live 120V?
Will your multimeter test capacitors?
