Question about Mitsubishi Mr. Slim MXZ30TN Air Conditioner
Check the following:
Make sure the filter and the evaporator coil are clean. Also check condenser coil in the outside unit is clean.
When unit is turned on there should be (on the led display, inside unit) one green light on for the blower and another one for the compressor, both lights should be ON untill the unit reaches the preset temp. If the light for the compressor (usually the light on the right side) does not stay ON, check the outside unit.
On the outside unit, check that when turned on, both the fan and the compressor kick in and stay running. If the fan motor stops, the compressor overheats and the thermal proteccion shuts it down to prevent damage. Also, if the R22 gas is low, the low pressure switch prevents the compressor from running.
