Having problems with your Air Conditioners ?

I have the Mitsubishi split unit system with 24BTU for my bedroom, the problems starts after the compressor has started and the cold air has been blown through the indoor unit, this pleasure lasts for about 2 mins and then a strange sound from the outdoor unit , sounds like the power is getting low or some what, then it shuts itself down. A technician checked and said the compressor needs replacement..its 12 month old and works 6 hours a day!!!


Answers :

Ok, it can be two things.

  1. The outside unit needs to be washed with a water hose to rinse any dirt and debris that can cause a restriction in airflow over the outdoor coils. If they are allowed to get dirty, they can cause the compressor to overheat and shut down on thermal lockout.
  2. \015\012
  3. The unit has a small refrigerant leak and the unit doesn't have sufficient refrigerant for the system to run thus causing the compressor to shut down on thermal lockout. The problem with this one is that generally the inside coil will freeze up and you will notice that.
\015\012Compressors generally won't come on at all if they are bad. You can have a compressor go bad and still be running, but it won't cool at all. A bad install can cause a compressor to fail as well. Generally if the compressor fails within the first 10 years, you can bet it's because it was a poor install. This means that a proper vacuum wasn't pulled on the unit before initial start-up. Hope this helps.

It suppose to slows down and keep blowing at a slower speed so as to save money by having air blow across coils. It does not slow down now and compressor stays on for long time.

My unit's compressor will intermittantly stop working. The thermostat seems to keep the intake unit working but since it can't get the temperature down it never shuts off. We have been removing the batteries and letting the thermostat reset for 20 minutes. (thermostat Honeywell RTH23110B). After the reset the compressor will work again but will fault within a day.

The outside compressor and fan will not shut off. I have turned the thermostat system to Off and even to heat, but it will not stop. I went on a trip, increased the room temp to 80 on the thermostat and left. When we returned 2 1/2 days later, the coils were frozen and no air was comiing through the vents, even with the blower motor working. So I turned the unit to furnace and melted the ice on the coils, but had to pull the fuses on the outside box to get the compressor to shut off. Is there a

We have a 16 yr old basic 4 ton Carrier unit. Coolant was a little low when started it up this spring. Had it recharged but now believe there is a slow leak in the coil. Is this usually repairable? Could the compressor get damaged if it runs to low on coolant? And can the coolant leak fumes be harmful when inside the house? Thanks


If it has a small leak, it might be a pain to find but it is possible and yes it can damage the compressor. Also it can be harmful as it will displace oxygen. It's not combustible though. ... Air Conditioners
