Went to a Mitsubishi Electric Hight wall split today Model - MSH-18NV. Now i couldnt gain access to the condensing unit but i suspect the unit short on refrigerant.
What was happening i would run the unit on cooling setpoint 16 room temp 25 and the unit would start cooling albeit not well. Then after 10secs the Reversing valve would click and unit would run heating for about 10secs then compressor would shut off.
Now my question is, is this normal? Is the unit defrosting the indoor coil due to below specfied coil temp?
Im not to familar with these units and id like a bit of a heads up before i go back. I think its a gas issue but just making sure. Also if anyone has a service manual that would be great as well.
Thanx
