Default convergence of Omega's residuals problem

Hello everyone

I am using (SST-K omega transitional and energy) models to simulate the heat transfer and air flow across a heat exchanger. I have set the Residuals for all = (10e-6), when I run the simulation all the residuals decreased and it's look good but when Omega residual reach (2e-5) it starts to go up and down (just for omega residual the others are ok) and in some simulations it never converged.
I hope someone help me to solve this problem .

thank you
