Got a small williams through the wall unit with hot gas defrost. Evaporator has frozen up and is thawing out over the weekend.
What is a suitable defrost termination temperature for such a contraption?
3C seems a bit cool to me to ensure all the ice has melted but i'm more used to electric defrost.

Cheers Jon

15degrees then you know that any ice on the coil is defrosted

the location of the sensor is another important factor.

The probe is at the end of the coil. I think i'll put a new probe on it just to be sure anyway.
