Customer said blower was not circulating air through the house, but OFM and compressor were running. They had turned off the system. Turned on the system as soon as I got here and everything came on and was working. Found no wiring issues. Turned system off and on a few times to try and recreate the problem. Each time the system came on and worked without fail. Intermittent issue causing the blower to not work. Left quote for repair. Customer deciding between repair and replacement.
