[Closed] Replacing the fan motor of an oven

Anyone know their ovens?
The fan on ours (a CDA) was making a horrible groaning so got a generic motor unit to replace it. A bit awkward with the bolts but basically a simple job, two connections to the motor. Switch it on and nada - nothing happening in the lower oven (with the fan), although top one switches on OK. Any ideas on what I might have done wrong here? The motor looks like this:

Does the motor spin if you switch it on when it's not fitted to the fan? (wires connected, obvs)

Will try that - although I connected it without the protective grill and nothing happened, so the fan is not getting caught on anything.

The fan may be thermostat controlled try winding the heat up to full for a couple of minutes

Check the fan is free to rotate? A slightly longer spindle might not be obvious, but might have the fan blades jammed against the oven's body.

Measure (carefully) for voltage on the motor's contacts with a multimeter?

How much of the generic part's specs have you checked against the motor that come out? Any chance you've replaced a 12v motor with a mains powered one?

There is a small circuit board on most ovens that controls the fan, they are around £35, they quite common failure points for fans.
Check for voltage at the fan terminals, if voltage there, then you have a duff fan.
