My D55152 has served my well for maybe 8 years. I recently started a new framing project. OK so far. Then, last week, it started very "feebly"; slow motor for 5 seconds then full power. The next day, the motor would not start at all. Nothing, nada, nary a squeak. Oil is on the lower third of the dip stick but is clear. Tanks are empty. Temperature is circa 45 degrees in the shop. I understand the oil may be too thick and the compressor may have to labor but the motor should at least try... The compressor is always plugged directly into a 20A circuit with no extension cord. I plan to remove the block that attaches to the top tank where the pump output is connected. There's a line from this block to the switch and also a small, brass fitting with a tiny hole. Something there may be the issue. Perhaps if those items are disconnected, the motor will get power. If not, I fear the motor is toast... :-(((
