Question about Haier HWR06XC9 Air Conditioner
I turn the unit on, but only the compressor comes on, the fan doesn't. After a few minutes the unit turns the compressor off and back on again. But the fan is still not spinning.
Either the fan motor
the fan control relay
or the fan control relay switching transistor
the unit is re starting because the gas is not getting cooled
If competent check for voltage at the fan and work you way back

SOURCE: ++HAIER 3125. Fan shuts off.
hi! there it seems that your control circuit board is activating default set up or abnormal set up after recieving on control circuit board when you shut off the unit, there's a short circuit behind on holding relay when deactivation process is done, the holding relay should be cutting your entire source connection on compressor terminal when you shut off the unit, in this case try to isolate checking supply voltage behind relay and the supply source terminal of your relay, .try to check on this to your manual circuit diagram to lessen the complication of trouble shooting just focus on relay circiut,replace relay if defective.this is a hard job and should be done by qualified a/c technician. have a nice day regard and thank's a lot

This is called short cycling. It sounds like the compressor is getting hot and opening a bi-metal overload, which shuts the compressor off. The compressor cools, because it is not running and the bi-metal contacts close allowing the compressor to start again. This will repeat itself and is usually due to low refrigerant, which usually means there is a leak in the normally sealed refrigerant lines. The refrigerant cools the compressor windings and if it is low it cannot do that, hence the shutting off of teh compressor, cooling down process and restarting of your compressor. Short cycling will ultimately ruin the compressor.
If this has helped you please give me a rating worthy of my diagnosis.
