freon charge in a Dometic
Hi everyone. Is there anyway to verify low freon charge in a Dometic 15,000btu without installing a line tap and ambient air temperature is to cold to really check output temperature? Compressor load ...

Thank You Doug! I had never known that. I learned something new today.

You take a TEMP compensated AMP draw of the compressor. VERY accurate. There is a Compressor AMP draw stated on the AC model label. THAT amp draw is based on 95 degree ambient temp. So, you subtract 1 AMP for every 10 degrees below 95 degrees. ADD 1 AMP for every 10 degrees above 95. Lets say the Rating is 12.2 amps for the compressor. It is 75 degrees outside. Subtract 2 amps. The Compressor after running a minimum of 15 minutes will draw 10.2 amps. IF lower, by more than 1 amp, you have lost part of the charge. IF 80 degrees subtract 1.5 amp, same test. Doug
