I bought a Danby kegerator and started using it about 6 months ago. This is my first kegerator but honestly I really don’t think the regulator has ever worked. Tonight I put my refilled co2 tank on the kegerator and for some reason the regulator spikes up to full pressure and then the regulator releases the pressure when it gets high. It almost seems like some kind of safety setting. I really just want my regulator to be 5-10psi so I can pour beer but it’s not working. Any advice??
