When I arrived at the weigh station the Bard unit was not functioning. The unit would run for a few minutes and shut down when there was a call for cooling from the thermostat. I discovered that the high pressure safety switch was opening after a few minutes and then would reset. The time delay at the unit was functioning normally. The amp draw for the unit was in range for the breaker size. The condenser was packed on the inside behind the outdoor fan blade. The condenser was washed and the unit restarted. The washed coil was allowed to dry and the system was operated for 20mins after it dried to confirm that it would stay in service. The temperatures were checked and were in range. (77-58). The compressor amp draw did predictably drop by two amps after the condenser coil was cleaned. Thank you, Jon
