Oh, the compressor motor's borked or overworked and overheating, or its capacitor failed short (perhaps the motor is shutting off from thermal shutdown...but you get to find out whether that's so. Be safe.) Alternately the temperature sensors have gone touchy on you. Once you gently vacuum it clean, try keeping incandecent bulbs in series with the compressor to get an idea of how loaded that thing is as it runs for those 5 minutes or so; the load might change more than you expect, just pay attention.
Hopefully you won't have to replace the compressor or motor; but it's doable if you're a certified technician with like equipment (so you can handle the refrigerant decently.) Most shops will streamline a bunch of similar jobs together to cut the waste and setup time.
Bigger conditioners are so much more efficient than little ones...syndicate the A/C?

SOURCE: poetable AC compressor licks in for 10 min

It is probably either the high pressure switch or the frost control. The high temp switch usually trips because the condenser coil is dirty which does not allow it to exhaust heat very well. The frost control will trip if the system gets below 39 degrees on the pipes. This is usually do to low refrigerant or dirty filters. Good Luck!

SOURCE: ac BLOWING HOT AIR INSTEAD OF COLD

Check to see if your outside unit is running. If not, check the breaker. If it is running you may have an issue with the reversing valve. It looks like three lines coming out of the top and one on the bottom. Trace the wires back to see that they are tight and secure. Of course, TURN OFF THE POWER first. good luck.

SOURCE: My air conditioner is on but not blowing cold air and buzzes

The compressor is not starting. The buzzing noise you hear is the compressor trying to start and then the thermal overload trips. When it cools it will try to start again. Could be a bad capacitor or the compressor is bad. These two units need to be tested to see which one is bad. A capacitor is inexpensive. If it's the compressor it will be cheaper to buy a new AC.

E5 Outdoor activation of compressor over heatprotection or motor lock

Please clean the condenser coil. And also check out door fan motor rpm. Rpm may be less due to weak capacitor. Replace it.If motor locked you have to replace new motor only.

If helpful, please write.

My tcl split ac works for 5 min, then gives e5 code.


E5 s a communication error between the indoor and outdoor units. It is stated in the service manual that the wiring between the indoor and outdoor has probably separated at one end of the terminal block. Most of the time however, it is usually a failure of either the indoor or outdoor electronic boards. A multimeter and knowledge of how to read "communications voltages is required. The machine will continually assess itself electronically to make sure all components are working properly. If after a given amount of attempts to communicate with the outdoor unit the machine still cant "talk" to the other 1/2 , it will show an E5 error and shut itself down. You could try switching off the power at the isolator or meter box for at LEAST 15 minutes and then turn back on to see if it resets. This sometimes works. Do not, just switch off and switch straight back on again.

Showing error E5


E5 is error code 5.
It means the water is not filling correctly (or the sensors are not noticing the fill correctly). Make sure the water supply is on and hoses are not kinked. If all water supply is ok, then the valve(s) may be bad. They are expensive so best checked and replaced by a technician.

Ac unit runs, inside blower shuts off after 2 mins, compressor continues to run, t-stat still calling for cool


My central AC unit decided to stop on the hottest day of the year. It would start and run normally for a few minutes and then the blower would shut off. After checking the breakers, thermostat and overflow shut off (did not have one) I saw something about a blower motor capacitor. This was easy to get to and replace and my last hope before waiting for someone to come fix it. The capacitor cost $4.04 with tax and had my AC working again. Needless to say I was beyond happy. I hope this can help others with a similar problem.

It blows cold air for 5 min. and the it blows cool air for 15 min. the room warms up . Why does it stops blowing cold air continuasly???? The thermostat was disconectet on purpose so it coul clow cold air...


See if you can reposition the thermister on the facing of the evaporator coils. That could be it or the thermister might be bad. They don't use copper/mercury sensing bulbs these days. They use these cheap thermisters.

There is a lubricant that is added along with the refrigerant when an AC system is charged. The noise you hear might be the compressor starving for oil.

check to make sure that the kids didn't change any other settings. Is the themostat still set for cold not hot? Also check the temp setting. Hope this helps.
