I believe you mean compressor
vice condenser... the condenser is actually the coil through which the cooling water
passes to condense the gaseous freon back to liquid state.
Anyway, check the compressor
unit itself - there may be a red reset button you could press. If not, try to determine if the control panel
/ thermostat is calling for cool / sending its voltage to the relay that turns the compressor on. Perhaps read the voltage at the main compressor leads in order to see if one of the limit switches has interrupted the circuit (high or low pressure cutout).
You should be able to find the wiring
diagrams on the cruisair
site. Good luck!
