Help! A/C only works when below 100°
Hopefully someone can help me diagnose…
Cooking here in Lone Pine CA at 105° this afternoon.
I know the cycles / behavior of this Dometic Brisk 2 Air conditioning unit (15k btu), so I think can articulate what it should / not be doing.
It starts normal operation but I hear the compressor drop out after about 5 minutes.
I hear the relay in the module send what I presume is a command to cycle the compressor a few minutes later but nothing happens and it just blows warm air until I shut it off for 15-20 min. Then we can repeat the cycle. Once temps drop below 100° it seems to consistently operate normally (compressor stays engaged), but not totally confident on that yet. Currently the compressor engaging sounds like a much softer start than I remember over the years of operation. I am leaning a capacitor on the edge of failure but would appreciate any other input to verify. I typically maintain a 22° return / supply differential and unit appears to be clean well maintained otherwise. This has been an intermittent issue for a number of months now…
Thanks
Jeff
