What to Do When One of Your Ductless Mini Split Units Isn’t Running
Mitsubishi ductless mini split heat pumps not only offer you energy savings, but give you an efficient way of enjoying year round comfort in your home. A ductless system is less bulky and dusty than traditional systems and still provides you with effective air temperature control. But what happens when things aren’t working? When you’re dealing with more than one air handler, like a multi-zone system, it’s possible for one of the units to stop functioning. The following are some troubleshooting solutions so that you can get your system back to work:
Check Batteries in Remote
First things first: make sure the batteries in the remote are still good. This is an easy step to overlook with a ductless mini split, and it’s best to start with the simplest possibility. You can use the buttons on the front of the unit to test whether the issue is with the unit or the remote. If you are able to power on the system from the unit and not the remote, try changing out the batteries and then give it another try.
Double Check Temperature Settings
It may be possible that the temperature for the air handler is incorrect or that the mode has been switched. Make adjustments on the remote or the unit to desired settings and the ductless unit should come back on if the issue is resolved.
Power Cycle the System
We’ve all heard it before, "Try turning it off and on again." You'd be surprised how often this small trick can work. Make sure the unit is off for three minutes and then try to power everything back on.
Check Air Filter
For some units the air filter must be cleaned once a month. Check the air filter to see if this is causing the issue. If you clean the filter and it still does not power on, move on to the next step.
Check For Tripped Breaker
If the display on the unit is blank, the unit may have lost its power due to a tripped circuit. Go to the circuit breaker panel to check for this issue. If you find that it has tripped and needs to be reset, reset the breaker and try to power on the unit again. If you power the unit back on and the breaker trips again, there may be issues with the wiring and requires the work of a professional to resolve.
Contact HVAC Technicians for Repairs
In the case that you have tried all of the above steps and the problem still persists, you’ve done everything you can to troubleshoot the air handler. Schedule an appointment with our highly trained technicians to evaluate the issue, diagnose the problem and attempt to repair the system. More often than not, the work will be minor, requiring small fixes to motors and wiring. In extreme cases, the unit may have to be replaced. Call our technicians to have a professional evaluation to determine a solution. Air Conditioning
