Broken POA Valve?
I've been reassembling my A/C evaporator, expansion valve and POA and figured I'd adjust the POA for 134a. I wanted to get a bearing on where it was set at first so I set it up to test.
I hooked up the low side gauge to the POA and ran compressed air through the expansion valve into the condenser to build up pressure. I was expecting it to build up to 30" or so, but instead I almost immediately heard a big pop from the POA valve. Now it won't hold any pressure and blows right through (showing 12-15" on the gauge). The system worked reasonably well before I took it apart. I'm assuming that the POA is toast now? Is there any way to repair it? If I need to replace it, has anyone used one of these OEM-looking POA eliminator kits that make the compressor cycle? https://www.originalair.com/15-52-ac...iminator-valve
