I am a HVAC install mechanic that hasn't worked in the field in a few years and I'm in aposition where I have to repair a couple units. I never was a service tech, hopefully someone can help. The units are simple straight A/C with no thermostat. On the first one, the red wire to the capacitor in the outdoor unit keeps frying off. I replace it, but in a couple days it just fries off again. Obviously drawing too much current. What could the problem be?
On the second unit, the compressor turns on for about 5-10 seconds then cuts right back off again. The unit only has a suction port so I cn only read the low pressure side but the gauge is in the retard when I put it on. What are the options with that one?
Thanks for any help I can get.
