Mitsubishi Electric Mr Slim Troubleshooting: Fix It Now!
When troubleshooting common issues with Mitsubishi Electric Mr Slim systems, there are a few things to consider. If your Mr Slim is not cooling, it could be due to a dirty evaporator, incorrect sizing, a clogged air filter, low refrigerant levels, or a faulty thermistor. Cleaning the evaporator and ensuring proper airflow can help improve efficiency. On the other hand, if your Mr Slim is not heating, check that the AC is set to heat mode and that the filter is not clogged. Additionally, make sure the circuit breaker for the air conditioning unit is on and not tripped. Excessive overheating in the compressor can also cause the unit to shut off frequently. It is recommended to consult a technician if the circuit breaker continues to trip or if the compressor is experiencing issues.
No Heat
Possible causes and solutions for Mr Slim systems not providing heat:
- Check if the Evaporator is clean. It could be too small, the wrong size, clogged air filter, low refrigerant level, or bad thermistor. Clean the evaporator to ensure that the airflow is smooth and the unit functions efficiently.
- Make sure the AC is set to heat mode and the filter is not clogged. Check your thermostat and see if it’s set accordingly. If not, switch to heat mode and avoid using auto mode.
- Check if the circuit breaker in the meter box for the air conditioning unit is ON. If it has tripped, reset the circuit breaker. If it continues to trip, there might be a power issue that needs to be checked by a technician.
- Excessive overheating in the compressor can cause frequent shutting off in ductless mini-splits. Consider upgrading the compressor unit, especially if it is old and more prone to sudden failure.
Remember to refer to the specific Service Manual for your system and follow the prescribed steps for troubleshooting and repairs.

Why Is My Mitsubishi Electric Mr Slim Not Cooling?
| Why is my Mitsubishi Electric Mr Slim not cooling? |
There can be several common reasons why your Mitsubishi Electric Mr Slim system is not providing cool air. One possibility is that the evaporator is dirty. A dirty evaporator can restrict airflow and hinder the unit’s efficiency. Ensure that the evaporator is clean to guarantee smooth airflow.
Another reason could be that the system is too small or the wrong size. If the system is undersized for the space it is cooling, it may struggle to provide sufficient cooling. Make sure that the system is sized correctly for your specific needs.
A clogged air filter can also impede cooling. A dirty air filter can limit airflow and reduce the system’s ability to cool the air effectively. Regularly clean or replace the air filter to maintain proper airflow.
Low refrigerant levels or a faulty thermistor can also lead to cooling issues. If the refrigerant level is low or if the thermistor is malfunctioning, the system may not be able to produce cold air. It is important to check and address these issues if necessary.
By troubleshooting and identifying these common issues, you can help ensure that your Mitsubishi Electric Mr Slim system is operating at its best and providing optimal cooling performance.
Why Isn’T My Mitsubishi Electric Heat Not Working?
