I have an older samsung mini-split (AQ18A0RCF). It works fine summer and winter but, on cold days, it creates a good amount of ice over the coil.
I already confirmed that the Defrost mode is working but its not enough to melt everything between 2 defrost cycle.
I checked the contractor map ... nobody listed in my area (North shore of Montreal)
Do you have an idea of how I could change the interval between defrost cycle ?
Is it possible to force the defrost mode manually (to melt ice when required)?
Thanks for your help
