Question about GE Zoneline AZ38H12DAD Split System Air Conditioner

3 Answers

Short cycling My GE Zoneline cycles for approximately 10-15 seconds every 10 minutes or so, even when the unit power switch is in the stop position. No heat is generated , the fan just goes on and off. This is very disturbing in the evening hours. Temp outside is approx. 30, inside temp 60-65. Can I adjust this with the limit switches under the main cover?

Re: Short cycling

The most common cause is the fan relay on the main circuit board. However, if the outside temperature is 30degF and the inside is 60-65degF then the cause could be the insulation is ruined or missing on the backside of the unit's firewall. This can cause the unit's internal thermocouple wire to read below 45degF which is the freeze sentinal temp level. Anything below this temp level will cause the unit to come on for a few minutes to warm up the air and bring it to 46degF or higher to protect internal plumbing from freezing.
The best way to check for this is to manually set the unit to one of the heat modes and the thermostat up just until the heater comes on. Let it run until the unit turns itself off. Then set the mode switch back to Off and see if the unit still cycles on and off as before.
If it does then the main circuit board should be replaced unless you are comfortable de-soldering and re-soldering another fan relay in place.

Re: Short cycling

If the unit switch is in the stop position and still operating may be there is something wrong with your control. Try to unplug the unit to reset the control error and operate it for testing. But if the symptoms persist please call a qualified technician.

Why is there a ***** smell?

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.

Ge zoneline az55ho7d when i tunr on it comes on fine, but after 10 minutes the fan in back side stop running and front fan keep running so throw only air no cold air. so what is wrong . is it motor for the...

Could be lack of service. The unit depends on a clean evaporator and condenser coil. The "other" motor you hear is the compressor starting or stopping probably due to either a high pressure or low pressure switch, or thermal cut-out.

Air conitioner turns on by itself

The GE Zoneline units have small DIP switches inside the unit where you can turn various functions on or off. The units have a feature called Heat Sentinel that turns the A/C on at a certain room temperature, even when the unit is turned off. It also has a Freeze Sentinel that turns the heat on automatically, even when the unit is turned off. You can turn off the heat and freeze Sentinel features with the DIP switches in the unit. There are other features you may want to turn off. Read the owner's manual and it will tell you where the switches are and which ones turn off the features. Hope this helps.

Problem with GE Zoneline 5200 model

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!
