Need help identifying component

[vinovino]

Need help identifying the component and a possible replacement parts.
The designator says FL14, I think its a kind of filter but I don’t know what kind.
It has 3 pads underneath, the middle pad is connected to ground.
It is around 2mm size.
Please see attached images of pad and the filter itself beside a ruler.

What is this out of?

FL20 also looks cracked.

FL15 looks normal. You can take it off, rig it up and measure it with NanoVNA. It's a coil, two coils with ground in the middle. Unless FL15 pin to ground does not measure as coil, then it is a capacitor, but the marking say L, so I suspect a coil.

All these 3 components should have same exact values. Measure FL15, and use two small coils (or caps if it is a cap) in place of one.

woul be as mentioned  FIlter line  smd      inductive most of the time, but some  do include capacitors  ...

Could FL15 and FL20 (and FL14) be T filters?

Did someone replace FL20 (and FL15) with the wrong part and end up shorting it to ground? Is the centre pin grounded (yes it is, I just reread the OP)??

Attached is another view of the board with the FL14.
FL14 1st and 3rd pin are normally shorted then it became shorted to GND (2nd pin) causing the F2(400mA fuse) became defective.
Connector J3 have a cable with approximately 400mm long that came from the secondary side of the instrument transformer.
Also the voltage that pass thru the F2 fuse is around 28VDC and 23VAC.

do you have access to an lcr meter ?
