Air conitioner turns on by itself

I worked extensively on GE Zoneline AZ Air Conditioners and Heat Pumps while a Maintenance Superintendent at a Senior Citizen's Apartment Complex. Not knowing what type of smell to which you are referring, I can assure you that other than "burnt electrical" smells, the only smell that could possibly be produced would be that from within the INDOOR SPACE. Perhaps something has made its way into the INDOOR AIR FILTER? Perhaps that INDOOR AIR FILTER needs to be cleaned. To clean the INDOOR AIR FILTER, simply lift both of the filters from the front cover, take to your clean bath tub. Run EXTREMELY HOT WATER from the back of the filter to the front of the filter. Then, fill your bathtub 1/4 way with EXTREMELY HOT WATER. Add 1 cup of Hydrogen Peroxide and 1 cup of Real Lemon Juice. Set both filters in this solution for 30 minutes; then rinse with clear water. Set filters up to dry for at least 2 hours in the sun or an air breeze. Replace filters into the GE Zoneline.

Also, not knowing how OLD your GE Zoneline system is, the COILS may need to be cleaned. To do this, simply turn OFF your GE Zoneline unit and remove the front COVER of the unit. Next, mix in a spray bottle 4 packets of LEMON flavored KOOL-AID (without SUGAR) and water. Shake well. Spray the INDOOR COILS of your GE Zoneline unit with the entire contents of this mixture. Let set for at least 10 minutes. Then turn your GE Zoneline to the COOL position. The citric acid in the lemon kool-aid will be forced through the coils to continue to remove any dirt, dust, debris and effectively CLEAN those coils. This will also provide you a LEMONLY odor within your room. Simple and cheap.

Enjoy your GE Zoneline unit.

Has the auto timer been accidently turned on? Does the machine have a delayed start option? Check the remote or the controller on the machine itself. You may have to reset them.

sounds like a mainboard problem

Hmm!! seems a little bit silly but did you ring the installer?.

If it was done yesterday they have a duty to support the installation be it major or minor

And it should be free

those are the specs. It is possible that the transformer is out.

theres a heat relay and also the wire used for heat.either could be bad.

One might think so, YES the compressor is running till it gets hot and tripps on hi-temperature, and after it cools down awhile, the switch willcautomatically reset itself and back- & forth......Thank-you-very much!

scrap the unit for alumimun and copper and buy a forty lol

well this is a very subjective question. How mechanically adept are you. If you know where to find the replacement OEM part, then its a mater of taking the control panel apart and replacing the wires one at a time from the old thermostat to the new one. It will have a sensor probe that will need to be routed and attached to the coil somewhere. The same place as the old one. make sure the bulb (if it has one) is not damaged. This may go without saying, but make sure the power is off first.
