Mini split repair
We have a 13 SEER , non inverter , 12,000 BTU mini split in our living room . We DIY installed it , maybe , 5 years ago .
It had been " struggling " / hard starting recently . Yesterday PM it stopped cooling . The compressor would not start . This morning , my Wife helped me work on it . First thing , I put the hoses & gauges on the low pressure service port . Turned it on & verified the compressor was not working & verified it was not out of R-410a refrigerant . We next removed the top sheet metal cover of the condenser / outside unit . This revealed the electrical . Located a 45 mfd capacitor . Removed it & attempted to test the capacitor with my ohm meter . Inconclusive . Got online & went to the Johnstone Supply website & verified they had the capacitor in stock . For a little less than $ 13 , I decided to drive over there & purchase a new capacitor . I had a Dr. appointment right after lunch , so , by the time I ate lunch , did not have time to install the capacitor . When I got home from my appointment , I installed the capacitor and turned the mini split on . It seemed like it might have been cooling , some . Left it running while my Wife and I went to Walmart to pick up a box fan . Upon our return , the temperature of the living room had come down , some . I lost some refrigerant this morning . Leaky blue low pressure / suction side hose . I plan to use a different blue hose and check pressures again , in the morning ( around 106F this afternoon and too hot for this old , fat man to mess with it in the afternoon ) . May have to top off the R-410a refrigerant . I have a jug of R-410a in the utility room . Then we will see what we will see . God bless Wyr |
