Common Problems You May Have

The MHI Air Conditioner won’t turn on

  • Check the circuit breaker at your meter box
  • Check the isolator switch at your outdoor condenser
  • Check to see if your remote-control unit has power.
  • Take note of any error codes on the control unit.
  • Check if your home’s electricity is working.

The air conditioner is on but doesn’t seem to be heating or cooling the room

  • There might be a problem with the filter (filters should be clean every 3-6 months).
  • Is there any light from your zone controller?
  • Check power supply 

There is a strange odour coming from the unit

It can be a sign of foreign contaminants, like moulds or pests, that build up over time. Physically remove the pollutants. Ensure your flexible ducting is not damage this is how rodents may have got in to nest. If flexible ducting is damaged ensure the damaged piece is replaced. Because the smell will still be present if you repair the damaged piece.

I’m experiencing leaking water from the indoor unit

  • It is not a regular occurrence but the drain can get block from time to time. Check to see if the drainpipe is free from obstructions because the indoor unit regularly produces water and must be able to drain away.
  • The drain can also be disturbed from the original installation. Ensure there are no valleys in the drain pipe and it has a fall to exit your roof space.
  • If water is still leaking on your ceiling. Your drain may be broke or have come loose from the fan coil. So if this is the case call a service technician to repair

If Problems Persist Talk To A Specialist

These troubleshooting tips should get you through most of your operating concerns. If the issue is still there, however, it might be a sign of something more serious. It’s best to call in the services of an air conditioning specialist. Because if the problem is left unattended it may cause further damage to your Mitsubishi ducted air conditioning system. Or more importantly your home

Air conditioning units need to operate in a particular way. If something is blocked or damaged this will not happen. It may also make the machine a hazard within your home. So my recommendation would be if unsure have it serviced by an HVAC air conditioning technician.
