My unit turns off by itsself

Recently my a/c shuts off after being on for about 7 hours. We like it really cold, so we use it on high at the lowest temp. It shuts off and the power button blinks and we can't turn it back on. Yesterday we drained it and it started right back up again....... is this the problem? We've never had to drain it like this before...... maybe once in awhile but not everyday.

Re: My unit turns off by itsself

Probably is the problem. These units have a float switch in them and won't run if they fill up to protect your floor. What you can do is connect a tubing to the drain pan and either drain it out side or into a larger container. Hope this helps 2rns4u <*{{{>(

Never shuts off

You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset.

I have a Sharp AF-S80FX A.C. unit. Whether on cool or fan the unit keeps tripping the breaker on the plug with an E1 message. The filter has been removed and cleaned, but it really wasn't dirty.

It doesn't turn on at all

Check to see if there is power getting to the air conditioner. If it is a 110-volt unit, plug a lamp or other device into the same outlet the air conditioner is plugged into. If there's no power, check the fuses or circuit breakers. If there's still no power, you will need to contact a qualified electrician to restore power to the outlet.

If there is power to the appliance but it is still completely dead there may be a problem in one or more of the following areas:

I have a 2006 Gulfstream Cavalier 8'x 32' Fema Travel Trailer with a Dometic Duo Therm AC unit which I have recently replaced the fan motor on. Had the dealership bench test motor prior to lea

There is ice forming on the evaporator coils. This is either from a low freon charge or a leak in the seals or windows and doors. Could also be that the drains are not working and water is building up and freezing

AC compressor cuts off and on every minute or so.

The voltage thing is a normal for high ampere appliance and well within its design. However coming on for a short time and cutting off indicates a compressor running out of spec. Too high or low pressure. On a very humid period of several hours a unit too small for the cooling need can freeze over on the inside coil. Shutoff the unit for several hours to allow thawing. If in the 7 years of use the unit hasn't been dismounted and serviced there could be dirt and debris clogging the inside or outside coils. These finned coils are are aluminium and easily bent. If enough surface area is restricted by damage a repair may not be possible.

I have a shenbao mennelium aircon its gets cool after i turn the unit on but after 10-15 min it stops blowing cold air i have to shut the unit off and then back on to get cold air and also the compressor...

Check the fan,to make sure it is really turning fast on the high mode with ac on,not just fan.It sounds like the fan is slowing down,and not cooling the condenser,therefore cause the head pressure to rise,and producing warm air.The fan motor would have to be replaced to fix the problem if this is the case.

Hot water is too hot. Setting is at lowest setting. Just above vacation.

Sounds like the temp sensor might be bad or getting ready to go bad. there really is no way that I can test it online for you . But I am prestty certain it going bad.. there is one thing you can try though. .. trun it up to high and leave it there for a bit a minute or so then turn it down and see if it shuts off. then wait 24 hours and see what happens .. Wish it was easy for you but its all I can do really Let me know Jon

My first guess is a dirty outdoor coil would give same symptoms you are having, high head pressure caused by the lack of air flow thru the coil, preventing proper heat rejection.

Hi and welcome to FixYa, I am Kelly,
This certainly sounds like a low system coolant level issue. Have someone check the system pressures. Low side should usually be 65 to 70 unit running. High side will vary with outside temps any where from 135 - 170. If you do not have good low side pressures it will affect the high side pressures also. This is really the only way your going to sort this one out.

Look around the evaporator and the condenser for any signs of OIL or dark spots caused by oil. That is usually an indication of a system coolant leak.

Thanks for choosing FixYa,

Kenmore AC compressor on and off while outside unit fan running

If the out door fan keeps running and the compressor cycles off that would be the overload in the compressor.
What keeps the windings cool is the refrigerant back to the compressor.
For the overload to cycle it would have to be either not enough cooling back to the compressor or high amp draw, which could be the metering device (txv or orifice) or low on charge, or other things would be a bad capacitor, sometimes a bad start relay not staying open, when compressor gets up to speed or anything causing the compressor to draw high amps.
To check the refrigerant, he needs to check the superheat at the compressor it should be appoximately 12° to15°, and next time the compressor goes off if you shut the power off and feel the top of the compressor and if it's hot 130° or higher it's probably refrigerant.
