Troubleshooting a problematic Mitsubishi appliance
If the air coming out never gets cold or your system stops working properly, then you may have a problem that needs your home repair skills.
The solution? First, check your thermostat setting. Often, the problem is that you haven't set the temperature properly or someone has accidentally turned the thermostat off. In summer, make sure the unit is turned to "Cool" and set on auto; try the opposite during cold months. If that doesn't solve the problem, then check the fan blades for damage and coils for debris or dust buildup. Low refrigerant can also prevent the unit from cooling or heating properly. That may require finding a leak in the refrigerant system.
Is your Mitsubishi camcorder hesitating for an unreasonable length of time when you try to play back a video? It's a fairly common issue, and there are a few possible fixes. Sometimes, cleaning the heads will get the camcorder working right again. However, the problem may be caused by excessive humidity getting into the case. Some home repair enthusiasts have found that removing the battery for a day or two while leaving the unit open will allow any moisture to dissipate.
Then, there's the TV. There are few things more frustrating than watching a movie and having the color fade from your TV screen. This seems to happen with some rear-projection systems. The colors are controlled by three CRT guns that control blue, red and green color combinations; whichever color along a particular spectrum is fading may need that gun replaced. The issue may also be caused by a bad controller chip if the circuit board is older.
Is your Mitsubishi AC running on and on?
Having cool air is nice when the warm weather sets in, but sometimes, you can have too much of a good thing. If your wall unit is running continually, it may be one of two reasons. Mitsubishi air handlers use sensors to detect room temperature and control the cycles. If the sensor isn't positioned properly next to the coil, it can malfunction and cause your unit to keep running. Try repositioning the sensor. If that fails to solve the problem and the unit is the correct size, you may need to replace the sensor.
Another possible issue may be that your air conditioning unit is simply too small for the room. This will cause it to run constantly as it tries to bring the room up to the proper temperature. You may try placing the unit in a smaller space or moving up to a larger unit if relocating it isn't an option.
