Check to see if you didn't do something like I did and cut the control cable while doing yard work.

Physically check that first. May save you some time :)
You can switch the EL and AZ cables to see if AZ works again. That's a quick test to see if the pot isn't the problem.
The start of that thread also has some great suggestions. https://x.com/NU1U_ant/status/1828046249481666742

I repaired recently the EL side of the control box. It was working through external control from the CSN SAT controller but it would not work manually. Now the AZ is frozen and won't work manually or through external control. I'm going to check out the roof top connection tomorrow but I'm anticipating the worst like a bad internal rotor pot.
Can any one give me some voltages to check from the controller and what to look for externally at the rotor itself. Perhaps all this is available somewhere online so a pointer to that would be most appreciated.

Unfortunately I believe it's the rotor. Inspection of cables topside and at the shack and reversing the AZ and EL lines at the controller yielded the same result. The AZ rotor is dead. At age 75 I'm afraid I could be looking back soon at the good years of enjoying this hobby as I'm not sue I have it in me anymore to get up and down from the roof, tear apart arrays, break down rotors, fix whatever the problem is and then put everything back. Sad but time to face facts I'm afraid.
