As Martin said 5107 is probably the one.
I have no recollection of a 1507 fault code for any Citi Multi machinery.
I think there is a 1607 ,which if memory serves me correctly is very rare and is a configuration issue.

Just a thought check SW3 - 8 on the outdoor board it's the refrigerant selection switch.
On an R22 model it should be OFF
I wonder is the unit looking for something that's not there.
Has somebody changed a board recently??

I cant help on this one :confused:
YMF-B was R22
During the next generation of City Multi YMF-C they changed over to R407c so early models were R22 & later models were R407c.
I dont have any notes in my YMF-B or YMF-C manuals about any 1507 fault.
