7-3-3. Only compressor unit does not run.
A. Check setting temperature.
B. Check compressor and electrical parts.
If the unit is turned off during cooling, DO NOT restart it immediately, as this 
can damage it. Wait at least 3 minutes or so before starting it again.
The compressor does not start up immediately even when the MODE selector 
switch is set to COOL or HEAT (It starts operating in about 3 minutes).
This is because rough 3-minute timer is built into the heat pump model in order
to protect the compressor. When operation is started up or restarted, the fan 
operation begins immediately but the compressor starts operating after about
3-minute lag.
