I've had a massive issue with water in my airlines here in east Tennessee. After shopping a bit I decided that a refer dryer would be the best solution for me.....and then I seen the prices. On a fluke last week I got on ebay and found an add for a "damaged" IR D18n that was flashing a PF1 code and would not engage the compressor, and it had fall damage. After plugging the PTC sensor up (someone at the factory failed to, no possible for it to come loose from the fall) the thing is working like a champ. Just wanted to share this if anyone happens across another.
The black and white connector would be the one that caused all the fuss.
