On this last trip my A/C quit, no fan no compressor. I had previously replaced the ceiling fixture because the original plastic filter holders had broken. Troubleshooting the unit discovered that all was good inside but no A/C. Because I'm getting too old to be making a habit of crawling around on the roof I took pictures and ordered the 3 possible parts. 47uf start cap, 20+10uf run cap and the PTCR. I ordered and replaced these 3 parts and all is well. On the bench the PTCR measure 38ohms in both directions. The 47uf start cap measured 47uf. But the 20 +10 only measure 6uf on the 20 uf section. Could have saved myself some money (the PTCR is expensive at $60) but to me it was worth it to only climb on the roof twice. BTW for some reason my A/C has always been reasonably quiet.
