Basement a/c
I am getting a 4 light flash from the green LED on control panel. 4 light flash code says DOB running. I have NO idea what DOB running is. Example: ODB= OutDoor Blower. IDB=InDoor Blower. HELP, please. Manuals have no mention of DOB

- It was many years ago when I went to tech school and I haven't played with it much. If they think the power may be interrupted from time to time the put that relay in to stop the compressor from coming on after a short power interruption, because of head pressure. I think it would be about a 5 min timer and would only come on if the compressor was running when the power went off.
- Seems you found one of those undocumented codes ...
Using Google this is all I found and it points to short cycling of the compressor. Once off, it tried to cycle back on too fast.
Short Cycle
Using the model number you might find more using Google.
