Coleman Roof A/C Not Putting Out Cold Air
The front roof A/C on our 1996 38Z quit putting out cold air this afternoon. The rear roof A/C , thank goodness, works great, and is keeping the rig comfortable.
The front A/C blower fan works fine. The filters are clean; in the Texas summer heat I clean them every week without fail. In fact, I cleaned the A/C filters this morning. I can hear the front A/C compressor start and continue running. So it's not a case of a bad start or run capacitor. The front A/C blower fan runs and puts out airflow as strong as ever; there is no ice blockage. The front A/C compressor is definitely running, because I can hear it start and run. No strange electrical smells or unusual noises. No popped circuit breakers, or "shedding" by the Intellitec ECC. The front A/C unit sounds the same as it always has.
I turned off both roof A/C units, in case anything needed to be re-set. I then started the rear A/C, and it's putting out cold air as I type this. But the front A/C is not putting out cold air, even though the compressor is definitely running.
Any suggestions before I climb up on the roof?
