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 of 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 Propperly?

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.

Are 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 are should be the causes:

  • The outdoor unit and indoor unit heat exchangers are dirty.
  • The air filter is dirty.
  • 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 in order to shelter from sunshine.
  • Reduce heat source.
  • AC cooling capacity reduces (normal).
  • Check leakage and rightly recharge the refrigerant.

Are You Feeling 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.
