Hey man, my Hitachi Room Air Conditioner RAS-72CHA3 has stopped blowing cool air, was comoletely fine this morning, we got home about an hour ago and its been blowing warm air with all settings on as

Slightly knock on the reversing valve, without breaking anything.

When its turn off, not unplugged, press at the same time ''Function Button" and the ''AUTO Swing" button on your Remote Controller.

If you can access the pcb inside, check the mini glass fuse

This model was produced approx 6-8 years ago a common problem is the compressor capacitor 50uf. I must of changed 50 of them by now.

dear sir

please reset you air conditioner by it,s remote to heat mode and check thermostat setting maybe it has been turn off after remove air conditioner,s electric supply plug from electric source . i hope after reset it will be able to work again.

hope answer the question
thank you
please vote!

yes, but I would try a "hard-start" kit before replacing the compressor itself

Hi; are You trying to cool or heat Your house. Also do You have a heat pump...need more info.

Check the breaker in the panel and the fuses in the disconnect at the outside unit. If that doesn't do it. call a heating and air technician instead of an electrician.

You can try universalremote.com but it cost me 15USD for digital delivery. Its better than being cold and I have spent hours on the net to no avail.
