This unit quit cooling. I opened it up and found a broken fan blade. I am in the process of removing the blade but I cant get it off. Is there a trick to get the special nut off the blade (also called propeller)? Does anyone have a service manual on this unit? Thanks in advance...gwb

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.
Check the back coil from the inside and see if they are plugged up, where the fan blades throws the water and air on the back coils ( If this is plugged solid and can,t get rid of heat, the Iamps wll climb and tripp out the overloads, and will restart later on when it cools down and continue to trip this cycles till the overloads burnout! Thank You very much!
Hi Laurelrobin, When the unit is on "low fan", it is fan only, and is recirculating room air. If the damper is open, it can also bring in outside air. If the space is not occupied for extended periods, it's OK to turn the unit "OFF", as long as you have a newer unit with Heat Sentinel, and the Heat Sentinel is turned on. Heat Sentinel will not let the room temp get above 85F, as long as the unit is OFF. Also, in most cases it's best to keep the damper closed. You can check your owner's manual for more info on the Heat Sentinel and other auxiliary functions. I also have an article on the temperature limiting functions of the GE Zoneline.
Feel free to contact me at greg.mcnary(at)airdistributors.com if you need further info.
Heat pumps have saftey circuits that prevent liquid flooding of the compressor. Inadequate airflow across the evaporator in cooling can trip this circuit. Have your package unit serviced with particular attention to cleaning the evaporator coil and be sure your filters are clean and changed frequently in the summer months. Hope this helps GL!
