hi,
I replied to a similar post, but in addition, get rid of the thermistor if possible.
Please check the rating of the CMC and differential inductor and if possible, use a lower resistance inductors.
By the way, please check your primary clamp connection.D2 should be connected to the anode of D3. Please refer to AN49 for further tips.
