My AC keeps burning transformers in the past 6-9 months. I had a

was burned out everytime. The transformer is 220V input for the 24V
output.

Are you SURE its a 220 v input transformer? All such transformers I
have seen have been 110 v input. Applying 220 to a 110 transformer
would burn it out in short order.
