Our Redhawk 24B did this a few weeks ago. The fan ran but no cold air, compressor didn't seem to be working. Set up an appointment to take it in on 10/7. In the mean time I decided to check the breaker. After finding the right breaker I switched it to the off position. Waited a few minutes then switched the breaker back to the on position. Made sure it was on. Moved the thermostat switch to AC. The AC came on and the compressor was working. Apparently the breaker had initially tripped but not enough for me to visually see that it had tripped. As of this writing, the issue has not re-occured.
