20 Most Recent Mitsubishi MSH09TW Air Conditioner - Page 3 Questions & Answers

Hi there,

Please check all the followings -

1. Ensure the air conditioner is installed properly. Window units should have front slightly higher than the rear of the air conditioner. A 1-inch difference between the front and the rear is sufficient for proper draining. This allows the water to roll out the back of the unit. If the front is lower than the back, then water can drip into your home.
2. Prevent a warm airflow from settling around the air conditioner. If your air conditioner is in a position where there is a flow of warm air, condensation occurs. The condensation can cause a buildup of water that may drip inside of your house.
3.Unblock the air conditioner's drain hole. The back of an air conditioner has a hole or groove that allows water to escape and drain off. If it clogs, the water cannot flow and may back up and drip inside your home.
4.Check for icing. If your cooling coil is icing up, the melting ice may drain into your house. If you can access and check your air conditioner's cooling coil and find ice forming, contact a service professional.

Good Luck!!

Sounds as though you have a bad motor. Once the motor heats up the winding swell causing the motor to constrict itself. Once this happens a thermal overload switch kicks in shutting the motor down to prevent fire. Hope this helps you Philip. Good luck on your repairs

Small fuse located in control panel blown most likely. Check it.It is hidden from view. Control must be removed to get to it. That is all.

The evaporator unit has a remote board in it that communicates to the remote every second. The interference your neighbor is coming from that and probably not the pump. A new remote board may just cause the same interference so I doubt the dealer will replace it. You can always ask. Try contacting Mitsubishi at www.mrslim.com. they have a contact page on their website that is very handy. They also have a technical manual under Library for your unit. Good Luck.

Sometimes after you replace the batteries in the remote, there is a communication disruption between the remote and the wall hung evaporator. With fresh batteries installed, take a paper clip and press in on the "reset" hole located on the remote. Yes you will have to reset the clock but it may help your situation. Then you will need to turn off both the inside unit as well as the outside unit. You must first turn back on the outside unit then the inside unit. If it continues as you have described, it could be a relay on the Main PC board and the board will need to be replaced. If all other functions and modes work, you will probably not have to replace the Receiver PC Board.

An EO error indicates an electronic error caused by either a control board problem or a problem with supply voltage to the heater. A single EO code is not cause for concern, but for repeated EO codes

Mitsubishi... | Answered on Dec 29, 2020

Check the code to see what that one means.

The codes are on the inside of the indoor unit cover. See this link to find them.

It's likely being overworked and therefore growing mildew on the fins. Clean the filter and rinse the coil with mild soap/water mix. Wipe down the unit with a damp rag.

14 flashes is a fault code. You need to determine which light is flashing and look at an online Mitsubishi fault code analysis chart for your model. The light(s) that flash determine the fault. Power, defrost, timer light flash all mean something different.

It is, more than likely, that it is not coming from your unit. Is someone burning candles? If they are, please stop burning them and use a candle warmer instead. The burning flame of most of the candles today, produce a lot of very unhealthy pollution in the soot that they produce, not to mention the health aspects to you. Scented candles are the worst. The unit usually gets blamed for picking this up and redistributing the particles back into the air.
