A customer very recently had a small fire outside her home. This fire swept past her a/c condensing units and melted a section of the t-stat wire going to two of the five units. Luckily there was enough slack in both runs allowing me to cut out the damaged part and reconnect it. One of the effected units work, the other doesn't. I didn't have time to really look into this as I wasn't even there for this task and I had to go elsewhere. I did take the access panel off the unit and saw no voltage at the contactor's coil terminals (With the digital t-stat set to cool). In all my years I never had to troubleshoot such a circuit, nor have I had to replace many t-stats, like two in my whole career, so where to start trouble shooting?
I'm going back there tomorrow which leads me to another question: The pipe insulation on the suction line has some visible heat damage and the customer wants me to replace the blemished sections. What's the typical size suction line for a 30 amp residential unit?
