Hansen Frost Master Controller
New to the forum giving this a try.
One of our controllers, times for the P.O. step. But skips through the rest of its steps right after ending back in refrigerating mode.
Is this happening to anyone else? Does anyone know why it does this?

Re: Hansen Frost Master Controller
Which model controller do you have?
Have you checked the settings and any external control switches?
Instruction manual if required...

Re: Hansen Frost Master Controller
I have ,yes. I've also replaced al the solenoids and the controller itself, but the problem remains. We have to manually defrost it and it'll take 2 or 3 tries before it actually stays in Hotgas and goes through the rest of its steps normally.
We don't use any external control switches.
