If your Trane Chiller's compressor fails, check if the motor winding is in an open circuit or if the phase current is excessive.
What causes a too short running period of compressor in Trane Chiller?
If your Trane Chiller experiences a too short running period of compressor, the control circuit might be intermittently connected. Check for poor contact of the contactor or loose wiring connections.
What to do if Trane Chiller has no refrigeration or heating signal?
If your Trane Chiller has no refrigeration or heating signal, check if the temperature switch is damaged or if the control wiring is disconnected or improperly connected.
What to do if starting voltage is inadequate (single phase type) in Trane Koolman R410A?
If the starting voltage is inadequate (single phase type) in your Trane Chiller, check for poor starting of the capacitor or poor starting of the relay.
What to do if Trane Koolman R410A Chiller has inadequate air cooling capacity?
If your Trane Chiller has inadequate air cooling capacity, it could be due to several reasons. First, there may be insufficient coolant, indicated by low superheat and supercooling degrees, so you should supply coolant. A blocked dry filter, indicated by a temperature change from the coolant pipe to the dryer room, should be changed. Improper regulation of the expansion valve requires you to regulate the expansion valve again. A blocked expansion valve, indicated by high superheat degree and high water temperature, needs repair or replacement. Also, too low water flow of the evaporator requires you to check the filter screen and regulate water flow. Non-condensed gas in the system requires system vacuumization and refilling with coolant. Lastly, a leak in the compressor valve with high suc...
