Hi and welcome.

Assuming that you have indeed swapped units like for like, then the most obvious thing to check is that you've terminated your wires correctly. The transformer/timer unit has two lives going in - a permanent one and then a switched one (usually taken from a light or a pull cord), the neutral and earth. This is so that the fan can continue to run on the timer AFTER the light/pull/whatever has been turned off.

There's then +/- 12v out to the fan. Just take your time with a meter to identify which is which. If you've managed to accidentally connect the fan to 230V then it will in all likelihood be very dead.

As above, the only real way here is to test with a meter to see what voltages you have
