That module should put out a steady 12V DC or more to run the compressor. With the compressor unhooked, it should read close to that, and 8–9V DC with nothing coming through on AC means the module is failing. The 638396 has been superseded by the 640291, but it's now discontinued too (638396/640291 power module). It only fits DE0061/DE0041 models with serials above 14328524.
