Is your Trane AC Unit Does Not Start?

These are the causes:

• Power failure.
• The power switch is off.
• The fuse of the power switch may have burned.
• Batteries of remote controllers exhausted or other problems with the controller

These are the solutions:

• Wait for the comeback of power.
• Switch on the power.
• Replication
• Replace the batteries or check the controller

 

Have Air Flow But Not Cooling Properly?

These are the causes:

• The temperature is not set correctly.
• Be in 3 minutes protection of compressor.

Let’s see the solutions:

• Set the temperature properly.
• Wait until the cooling came.

Do your Trane AC Units start or stop frequently?

These will be the causes:

• Refrigerant is too little or too much.
• Air or no concreting gas in the
• refrigerating circuit.
• The compressor is malfunctioning.
• Voltage is too high or too low.
• The system circuit is blocked.

By doing these steps you can solve the problem:

• Check leakage, and rightly recharge the refrigerant.
• Vacuum and recharge refrigerant.
• Maintenance or change compressor.
• Install manostat.
• Find reasons and solutions.

Are You Feeling a Low Cooling Effect in Trane AC?

These should be the causes:

• The outdoor unit and indoor unit heat exchangers are dirty.
• The air filter is dirty.
• The inlet/outlet of indoor/outdoor units is blocked.
• Doors and windows are open Sunlight directly shines.
• Too much heat resource.
• Outdoor temp. is too high.
• Leakage of refrigerant or lack of refrigerant.

Check the steps for solutions:

• Clean the heat exchanger.
• Clean the air filter.
• Eliminate all dirties and make the air smooth.
• Close doors and windows.
• Make curtains to shelter from sunshine.
• Reduce heat source.
• AC cooling capacity reduces (normal).
• Check leakage and rightly recharge the refrigerant.

Are You Feeling a Low Heating Effect?

Causes:

• Outdoor temperature is lower than 7 C
• Doors and windows are not completely
  closed.
• Leakage of refrigerant or lack of refrigerant.

Steps for solutions:

• Use a heating device.
• Close doors and windows.
• Check leakage and rightly recharge the refrigerant.
