Ryank Posted July 16, 2011 Share Posted July 16, 2011 I've got a CH 6H613 with a non-working A/C, the compressor does not want to run when the A/C is turned on. It does appear to have a refrigerant charge. There is a switch on top of the receiver/dryer that has a single wire and double wire plug on it. I pulled the double wire plug off and put a jumper wire across the plug at the wire loom, then the compressor ran and appeared to put out cooler air. So any thoughts on why the compressor won't stay engaged? Bad switch somewhere? I've heard some people talk about a binary switch that sometimes causes issues.Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/19791-93-ch613-ac-not-working/ Share on other sites More sharing options...

This precludes the compressor running and not circulating oil to lubricate itself.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
