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.
