SOURCE: arcoair central heat /air conditioning unit

The blower motor kicks on when there has been a 24 volt control failure.

This usually means that a limit switch has tripped.

Most likely that would be a high temp limit switch or a rollout switch.

First, make sure the filters are clean. and the evap coil is clean. If eaither are dirty/clogged, it will partially block airflow, causing the furnace to overheat, causing the high temp limit to trip.

A rollout switch typically trips for three reasons.
1 flame rollout into the burner compartment due to poor airflow.
2 overheating af teh metal plate the rollout is mounted to, due to dirty, old, rusted components.
3 a bad limit switch.

If your unit has an LED light, count the flashes and it will hepl popint out the problem.
(locate the wiring diagram/flash code list, and correspond the flash count, with the code.)

First, check filters.

SOURCE: Central Air Compressor Runs Constantly

Sounds like the contactor is stuck in the outside unit. Turn off the breaker or safety switch, remove the cover, and tap on the body of the contactor with a hammer handle or similar tool. If a click is heard you may have dislodged it and it may work for either a short time or indefinitely. (yeah ,I know that's kinda vague) Test it. If that doesn't clear it up, disconnect the thermostat wires just to make sure and re-test. If the compressor starts without the thermostat connected, you will need to replace the contactor. If you feel real handy, you could perhaps remove the cover, seperate the contacts with a screwdriver, dress the contacts with an emery board until smooth and shiny, and try again.

Auto/On set to ON. Fan runs.


Sounds like the thermostat, the way to verify is to unplug indoor unit, remove thermostat, take pic of wiring with phone or label the wires as to the terminals. Carefully twist the yellow,(Y) Red (R) and the green (G) together. Plug the furnace back in, if the unit operates normally, replace the thermostat. I am basing this on the fact that the blower speed is changing. This could also be an anomaly within the circuit board in the furnace section, not likely though as the outside unit (condenser) is not controlled n by the indoor board unless this is a heat pump. hope this helps.

Window unit (110) cools for a few minutes then stops cooling just fan air unit is about 6 0r 7 years old


It sounds like your compresssor is shutting off on an overload. After the overload cools down the compressor comes back on until the overload heats up and shuts the compressor off again.The fan keeps running as it is not on the same circuit as your compressor.

Hey, i have a MSZ-GA80VA and the head unit starts for a few minutes and then stops with the left light blinking. i also noticed that the outside unit does not kick in. Daniel


Is there some error code.? Without knowing error code, chances for yor your problem is:
If indoor working properly, there is communication problem between indoor and out door. Check for power in out door after 3 minutes of a/c switched on. If no power problem with your PCB. Replace it.

We have a msz-ga80va split cycle, indoor unit runs for about 5 minutes without cooling then cuts out, outside unit doesn't kick in at all


Just had the same thing happen to us with the same model (right on Xmas day).
Checked the circuit breaker is on in the fuse box. Power is on to the external unit. Filters are clean.
Internal unit activates... both indicator lights on. After 5 minutes blowing air it stops and the right indicator light goes out and the left indicator light blinks constantly.
The troubleshooting guide inside the internal unit (under the outer cover you open to clean the filters) suggests that 14 blinks is an abnormality with the external unit and refer to service manual.
Think we'll be calling a technician.

Red light blinking with audible alarm. Compressor


That is the compressor starting relay trying to start the cooling cycle and the overload protector kicking off. You can try installing a new start device for about $50.00 but you are most likely looking at a compressor replacement which runs about $400.00

Sorry for the bad news

Carrier hi wall split unit on light flashes 4 times ???


as i am a mechanic in sydney australia, i can honestly say that the chance of you getting help via carrier is very very slim... the reason it is doing that is that it has a legitimate problem unfortunately i have a carrier 42g250h which is flashing 4 times aswell... i have been waiting now 10 working days for carrier to call me to tell me what the problem is... if you can afford to do it, throw the damn thing out and buy a new one, i hate to say it but even an LG will work better than these heaps of ****
