City Multi 7113
Hey guys,
Had someone ring me about this code today 7113, loose connection on main board. Anyone come across this problem before. Its not a new install its been there for a few years. Was thinking maybe the recent bad weather may be the culprit.

Re: City Multi 7113
An enginner call me today with a 7113 fault on a YHM-A system.
After getting him to check a few things he found no voltage from the noise filter board to the Mnet board.
So outdoor unit not generating the 30v dc contol voltage for the system.
Engineer ran out of time & left site.
I am supecting power supply problem has caused dammage to the noise filter board but untill the engineer returns to site I wont be able to confirm.

Re: City Multi 7113
We've had a few M-Net boards and inverter boards failing due to snow getting into the electrics.
I believe there is a 'snow shield' of some sort to prohibit this from happening. Failing that, armaflex sheet will suffice.
