I mentioned the replaced parts only to show that the conversion has been done properly.

The temp fluctuates when measured with a thermometer struck in the duct. It takes about 1 minute to go down to 47 and then it goes up to 60 again, outside temperature is about 65. Last year it went easily down to 41 with high outside temperatures.

The compressor stays on. The small green lamp (arrow) in the switch sometimes goes out. If I look at the small window in the receiver/dryer I can see the fluid, no bubbles.
